Description

The present invention relates to a device, a program, etc. for sending a message to a user.

2. Description of the Related Art Systems that support safe driving by drivers of moving objects such as automobiles (hereinafter simply referred to as "cars") are being researched every day.

For example, one example of a system for safe driving is a driving safety support system (DSSS) that uses a vehicle information and communication system (VICS (registered trademark)).

DSSS is a system to prevent accidents caused by driver inattention or delayed judgment. For example, if it detects a motorcycle coming from behind a car when turning left, an optical beacon sends information to the car, and a message is played inside the car telling the driver, ``There is a motorcycle, be careful when turning left!'' Alternatively, the driver is given a warning or warning of danger ahead of time, such as ``Temporary stop!''.

Additionally, the safety performance of the vehicle itself has been improved through the use of advanced safety vehicle (ASV) technology, which is a vehicle equipped with a system that uses advanced technology to support the driver's safe driving.

Further, an example of a technique for supporting safe driving is described in Patent Document 1. The technology described in Patent Document 1 uses a radar or the like to monitor the behavior of the own vehicle and other vehicles, and notifies the driver of these facts when the distance between the vehicles is too narrow or when sudden braking occurs. By using such technology, the driver can understand when the vehicle's behavior is not appropriate.

JP2006-085285A JP2006-282111A

By using the various systems and vehicles described above, safe driving of drivers can be supported.

However, in the end, it is humans who use these systems and vehicles. Furthermore, human errors caused by humans cannot be eliminated easily.

For example, even if it does not lead to a serious accident such as a collision, a driver may be in a "near" situation due to poor driving manners.

Drivers may become irritated, impatient, or angry due to factors such as being inconvenienced by other drivers, their own time constraints, and stress from traffic conditions such as traffic jams. Some of them have feelings that are not appropriate.

If a driver temporarily feels this way, he or she will drive rougher, increasing the possibility of an accident occurring. Therefore, appealing to the driver's emotions while driving is essential for safe driving.

In this regard, Patent Document 2 discloses a system that acquires user biological characteristic information such as the mental state of the user while driving and performs hospitable operations to entertain the user based on the acquired user biological characteristic information. Are listed.

However, in the technique described in Patent Document 2, in order to estimate the driver's mental state, it is necessary to prepare equipment such as a dedicated sensor for measuring the driver's physical information.

For example, prepare measurement equipment such as an infrared sensor to determine the driver's complexion, a face camera to measure the driver's facial expression, posture, and pupil diameter, and a pulse sensor to measure the driver's heartbeat. There is a need. In addition, it is necessary to prepare a pressure sensor in the seat, measure the weight distribution on the seat with the pressure sensor, and detect small shifts in weight during driving.

However, such specialized equipment for measuring a user's physical condition is not installed in a typical car. Therefore, in order to realize the technology described in Cited Document 2, it is necessary to additionally install a dedicated measuring device, which increases the cost. Furthermore, it may be difficult to add new measuring equipment to a regular car due to the design of the car.

Therefore, an object of the present invention is to provide a device and a program that can affect the psychological state of the user while driving without adding a dedicated measuring device to measure the user's physical state, etc. do.

(1) Observation means for observing the situation in which a mobile object operated by a user is placed;
Control for sending a message to the user for switching the psychological state that the user would have if the observation result by the observation means satisfies a predetermined condition to another psychological state. means and
A device characterized by comprising:

In this way, it is possible to control the sending of messages based on the observation results of the observation means that observe the situation of the mobile object, so the physical condition of the user can be measured in order to send the messages. There is no need to add special measuring equipment for this purpose. Furthermore, in this way, it becomes possible to influence the user's psychological state during driving by sending a message for switching the psychological state that the user may be in to another psychological state.

To explain more specifically, in the general technology including Cited Document 2, etc., in order to understand the psychological state of the user, which is a prerequisite when entertaining the user, an infrared sensor is used to determine the complexion of the driver. Additionally, dedicated measurement equipment was required, such as a face camera to measure the driver's facial expression, posture, and pupil diameter, and a pulse sensor to measure the driver's heartbeat. However, if the above (1) is done, there is no need for dedicated equipment to observe the user's state, and if there is an observation means for observing the situation in which the mobile object is placed, This is good because it makes it possible to influence the user's psychological state. Here, the observation means may be realized by various sensors for observing the behavior of the moving body, such as an acceleration sensor, a gyro sensor, and an obstacle sensor.

The "mobile object operated by the user" may be a device on which the user rides and travels on a road or the like. For example, it may be a four-wheeled vehicle or a two-wheeled motorcycle, which are commonly used. Further, it is preferable that the content of the message sent to the user differs depending on whether the moving object is a four-wheeled vehicle or a two-wheeled motorcycle.

The user's "operation" may be, for example, changing the direction of the moving object using the handle or adjusting the moving speed using the accelerator and brake.

"Observe the situation in which the moving object is placed" may be defined as observing the situation regarding the behavior of the moving object. For example, if the observation means observes the moving speed of the moving object, the acceleration of the moving object, the steering angle of the moving object, and the operation status of turn signals, accelerator, and brake pedals, the specific behavior of the moving object can be observed. This is good because it allows you to understand the situation.

Furthermore, observing the situation in which the moving body is placed may be performed by observing the situation around the moving body. For example, if the distance between vehicles and other moving objects or interruptions from other moving objects are observed, the specific situation around the moving object can be grasped.

Furthermore, it is preferable to observe the current position of the moving object when observing the situation in which the moving object is placed. For example, the observation means observes the current position of the moving body. By comparing the observed current position with the map information, it is possible to specifically grasp the type of road on which the mobile object is currently traveling.

The "observation means" for performing these observations may be realized by a device that can observe the behavior of the moving object and the surrounding situation of the moving object. For example, it may be realized by various sensors such as an acceleration sensor, a gyro sensor, and an obstacle sensor.

Further, it is preferable that the control means acquires the information observed by these various sensors, for example, via OBD (On-board diagnostics) built into the mobile object. Further, as the observed information, it is preferable to obtain operation information of a turn signal, accelerator and brake pedals, steering angle information, and vehicle speed information obtained from the OBD.

These various sensors and OBDs are installed in general automobiles and general car navigation systems (automotive navigation systems), so it is possible to eliminate the need for adding new measuring equipment.

Alternatively, the observation means may be realized by a camera that captures images of the surroundings of the moving body, and the control unit may grasp the situation around the moving body by analyzing the images captured by the camera. Further, in this case, if the camera included in the drive recorder is used, there is no need to prepare a new camera.

Furthermore, the observation means is realized by a GPS sensor (Global Positioning System), and the control unit compares the position information acquired from the GPS sensor with map information to understand the type of road on which the mobile object is currently traveling. You may also do so. Further, in this case, if the GPS sensor provided in the car navigation device is used, there is no need to prepare a new GPS sensor.

The "predetermined condition" in "when the observation result by the observation means satisfies the predetermined condition" is when the mobile object is placed in a situation that causes the user to have a psychological state inappropriate for driving. It is recommended that the conditions are satisfied.

For example, the predetermined condition may be that the observation result by the observation means is the same as the observation result observed when the moving object is in a dangerous situation. For example, it may be assumed that the observation result by the observation means is the vehicle speed of the moving object, and that this vehicle speed exceeds the legal speed. Further, for example, it may be assumed that the inter-vehicle distance to another moving object is less than or equal to a predetermined distance.

The "psychological state that the user would have" when the observation result by the observation means satisfies a predetermined condition may be a psychological state that is inappropriate for driving the mobile object. When continuing to drive, such an inappropriate psychological state can be said to be a target to be changed to another psychological state. For example, psychological states such as irritation, impatience, and anger may be used.

The "other psychological state" is preferably a psychological state appropriate for driving the mobile object. For example, it is good to be in a calm psychological state without being excited.

The message for "switching" to another psychological state should be a message that changes the driver's perspective and returns to a calm state, in order to control the driver's irritation or anger. For example, the message may have content that represents the user's thoughts. For example, a message such as "Interrupting is terrible. I have to be careful." Furthermore, it is preferable to use a message that empathizes with the user's thoughts, such as, ``What you just did was surprising!''. Further, it is preferable that the message has content that changes the user's perspective. For example, a message like, ``If you are an adult, please give way to the car coming behind you! It will be more comfortable that way!''

The "control for sending a message to the user" may be a control for sending a message in a way that the user can perceive. For example, it is preferable to control a device such as a speaker or a display capable of sending a message to send the message so that the user can perceive it.

As a control method, for example, the audio data of the message may be stored in the storage means, and the audio data may be played back and output from a speaker at the time of transmission, or the audio may be sent out by storing the message in the storage means. It is also possible to store the text data as text data, generate a voice corresponding to the text data through voice synthesis, and output the voice from a speaker. Further, for example, the message may be stored in the storage means as text data and the text data may be displayed on the display. This is good because the user can perceive the contents of these messages.

Furthermore, for example, at least part of the control may be performed by a server or the like, and the electronic equipment in the vehicle may be controlled to transmit audio based on information acquired from the server through communication.

Moreover, the present "device" is preferably realized by a device that can be mounted on a moving object. For example, it may be realized as one function of a PND (Portable Navigation Device), an RD (Radar detector), or a drive recorder. These devices are equipped with various sensors such as acceleration sensors to realize observation means, and speakers and displays to realize control means, and it is possible to realize this device by using these devices. This is good because it allows you to

In addition, this device described above can be used to send messages that help drivers change their perspective and return to a calm state in order to control the frustration and anger that arises from emotional stress caused by dangerous actions from outside the vehicle while driving. It is preferable to use a device whose purpose is to send out.

In this regard, people engage in countless amounts of self-talk in their daily lives. Such self-talk includes things that are actually said out loud as well as things that are recalled in one's head but are not said out loud.

And this kind of self-talk occurs naturally even when driving. Furthermore, the content of this self-talk is thought to be very relevant to subsequent driving behavior.

Specifically, people become aggressive due to the emotional self-talk that comes to mind as a result of dangerous driving behavior. For example, if you are driving a car and are suddenly cut into by another car, you may start to think to yourself, ``Don't be silly when you suddenly cut in!'' become a target.

Therefore, this device sends out a message such as, ``How reckless are you driving? There are strange people in this world! I'm glad you didn't get into an accident.'' As a result, if you say things like, ``That's right. I'm glad I didn't have an accident.'', you won't become aggressive.

This is because the driver realizes from the message sent that an accident did not occur, even though an accident could have occurred due to the dangerous behavior induced by the actions of others. .

In this way, it is preferable that the present device is a device that sends messages that do not make the driver think of aggressive self-talk and supports the driver to change his/her perspective.

(2) A plurality of the predetermined conditions are provided, and the message to be sent is selected depending on which of the plurality of predetermined conditions the predetermined condition satisfied by the observation result is, and the observation means An apparatus that executes sending of the selected message when the observation result by the selected message satisfies a sending condition determined for each selected message.

In this way, the message can be sent at a timing that satisfies the sending conditions determined for each message according to the observation result.

For example, assume that a predetermined condition is met when another moving object suddenly interrupts the lane in which the moving object being driven by the user is traveling. It is not desirable to immediately send a message at a certain stage. This is because in such a case, an operation such as adjusting the inter-vehicle distance is required immediately, and the user should perform this operation immediately.

If a message is sent in such a dangerous situation where urgency is required, the driver may become distracted by the message, making it even more dangerous. Therefore, in such a case, it is advisable to send the message after this dangerous state has ended. For example, the observation means observes the speed of the moving object. Then, based on the observed speed of the moving object, the message may be sent on condition that the speed of the moving object has stabilized and it has been determined that the moving object is in a safe state. This is good because it makes it possible to prevent accidents from occurring.

On the other hand, if the user approaches a prohibited area, for example, it is preferable to send a message as soon as the user approaches the area. This has the advantageous effect of being able to immediately transmit messages that should be transmitted as quickly as possible.

In other words, depending on the content of the predetermined conditions, the message may be sent immediately when the predetermined condition is met, or the message may be sent when the predetermined condition is met and the conditions for sending are met. It is good because it can be set as follows.

(3) An apparatus characterized in that, after transmitting to the user a message for switching to the other psychological state, the device further transmits to the user a message representing an instruction regarding the operation of the mobile object.
This is good because it allows the user to perform operations according to the instructions.

The "message representing an instruction regarding the operation of a moving body" may be an instruction regarding the operation of a steering wheel, accelerator, or brake. For example, instructions such as "Please slow down slowly" or "Please leave a long distance between vehicles" may be given.

Moreover, if this is done, a message for switching the user's psychological state may be sent first, and then an instruction regarding the operation may be sent. In this regard, even if an instruction regarding the operation is sent out first without doing this, it is assumed that the user who is in an excited state may not calmly listen to the instruction regarding the operation. However, with this device, a message is first sent to switch the user's psychological state, and then the user's psychological state is first switched. For example, the user is in a calm state before sending instructions. This is good because the user can calmly listen to instructions regarding operations.

(4) If a traffic rule violation caused by an operation of the user is detected based on the observation results, a message is sent to the user explaining what operation should be performed to prevent the violation from occurring. A device characterized in that it transmits data to

In this way, the user can know what kind of operation should be performed to prevent a traffic rule violation from occurring.

"Detection of occurrence of violation of traffic rules due to user operation" is to detect when the observation result of the observation means is in a state where the observation result would be a violation of traffic rules. It is better to make it . For example, when it is observed that the moving speed of a moving object exceeds the legal speed limit, it is preferable to detect the occurrence of a legal speed violation.

In this case, the ``message explaining what action should have been taken to avoid the violation'' could be, for example, a message such as ``I stepped on the accelerator too much'' or ``I should have applied the brakes earlier.'' good. As a result, when a traffic rule violation occurs, the user not only knows that a traffic rule violation has occurred, but also knows how to perform an operation to prevent the violation from occurring. Therefore, the user can avoid making similar operational errors in future operations.

(5) When the occurrence of a violation of the traffic rules is detected, along with or in place of the message explaining what operation would have prevented the violation, A device characterized in that it sends a message explaining the content of traffic rules.

In this way, the user can know what kind of traffic rule the user has violated. This allows the user to know not only the fact that a traffic rule violation has occurred, but also the content of the traffic rule that was violated. In this regard, there are a wide variety of traffic rules, and it is possible that the user may not fully understand all the traffic rules, but the messages sent by this device allow the user to understand traffic rules that they were not fully aware of. This is good.

(6) An apparatus characterized in that the message is sent when it is determined that the mobile object is in a safe situation based on the observation results.

In this way, a message is not sent when the mobile is in a dangerous situation, but a message is sent when the mobile is in a safe situation. Therefore, the user can calmly perceive the message when the mobile body is in a safe situation. If this is not done, the message will be sent when the mobile unit is in a dangerous situation and the user must concentrate on the operation, and the user will not be able to listen to the message calmly. This is good because it can be prevented.

Furthermore, for example, a message is sent even though the mobile object is in a dangerous state, and the user's attention is drawn to the message, which diverts the user's concentration from operating the mobile object and creates a dangerous situation. This is good because it can prevent this from happening.

"The moving object is in a safe condition" may mean, for example, when the moving object is not in the middle of sudden braking or sudden steering, but is moving stably. Further, the "determination based on observation results" may be performed based on, for example, brake pedal operation information and steering angle information acquired from the OBD.

(7) Setting a threshold value for the numerical value of the observation result of the observation means,
An apparatus characterized in that the moving body is determined to be in a safe situation when a value obtained by quantifying the observation result of the observation means is equal to or greater than the threshold value or less than the threshold value.

In this way, it is possible to determine whether or not the moving object is in a safe situation by comparing the observation results with the threshold value. The "value obtained by quantifying the observation result of the observation means" may be, for example, the value of acceleration or the value of the steering angle of the steering wheel.

Furthermore, "it is determined that the moving object is in a safe situation when the value obtained by quantifying the observation result of the observation means is equal to or greater than the threshold value or less than the threshold value" means, for example, By comparing acceleration and steering angle with threshold values, it is determined whether the vehicle is in the middle of a sudden start or sudden steering, and if the vehicle is not in such a sudden start or sudden steering situation, it is determined that the moving object is in a safe situation. It is recommended that the judgment be made as follows. Also, for example, when a moving object is moving in a place where it should go slowly, it is preferable to determine that the moving object is in a safe situation when the speed of the moving object is less than a threshold value. .

(8) An apparatus characterized in that the psychological state that the user will have when the observation result by the observation means satisfies a predetermined condition is a psychological state that can adversely affect the operation of the mobile object.

In this way, it is possible to send a message for switching a psychological state that adversely affects the operation of the moving body to another psychological state.

For example, when a user is in a psychological state of being irritated or anxious, the system switches between these psychological states and sends a message to suppress the irritation and impatience. This is good because the user can drive safely in a calm psychological state.

(9) An apparatus characterized in that a message representing the user's thoughts is sent as a message for switching to the other psychological state.

In this way, the message represents the user's thoughts. As a result, for example, if the user thinks, "Don't drive dangerously with your current car!", a message representing the user's thoughts will be sent saying, "Don't drive dangerously with your current car!" . This is good because the message represents the user's feelings, which makes the user feel better, and the user's own thoughts and feelings related to ``Don't drive dangerously!'' are calmed down.

(10) An apparatus characterized in that a message whose content empathizes with the user's thoughts is sent as a message for switching to the other psychological state.

In this way, the message empathizes with the user's thoughts. As a result, the user feels that his or her irritated or anxious mental state is empathized with and understood, and the user's emotions are calmed down. For example, a message that empathizes with the content may be something like, ``What you just said surprised me!''

(11) A device characterized in that the device transmits a message that changes the viewpoint of the user as a message for switching to the other psychological state.

In this way, the message changes the user's perspective. When the user's psychological state is irritated or impatient, the user's perspective tends to lose flexibility and become short-sighted. However, according to the present device, since it provides an opportunity to think from another perspective, the user can grasp the current situation from a flexible perspective, which is good. A good example of a message that changes the perspective would be something like, ``Adults, let's give way to the car coming from behind! It'll be more comfortable that way!''

(12) A device characterized in that the message for switching to another psychological state is a message recorded directly or indirectly by the user.

In this way, the message sent becomes a message recorded directly or indirectly by the user. In this regard, since this device works on the psychological state of the user, the effective message differs depending on each user. In other words, the effective content of self-talk differs from person to person, and it is necessary to find the message that suits each person. Therefore, for example, the user can record the voice of the user's lover or family member (wife, children) directly using a recording device, or indirectly by asking a family member, etc., and send it as a message. It's good to do that. This is advantageous since it is possible to send a message suitable for the user who uses this device.

(13) An apparatus characterized in that the message for switching to another psychological state is a message selected by the user from among a plurality of messages.

In this way, the user can select his/her favorite message as the message to be sent. In this regard, since this device works on the psychological state of the user, the effective message differs depending on each user. In other words, the effective content of self-talk differs from person to person, and it is necessary to find the message that suits each person. Therefore, for example, it is preferable to prepare several patterns of voice quality and message content and allow the user to select a pattern that matches the user's own preferences. This is advantageous since it is possible to send a message suitable for the user who uses this device.

(14) An apparatus characterized in that when the observation result by the observation means satisfies the same predetermined condition multiple times, a different message is sent each time.

In this way, even if the predetermined condition is the same, the content of the message to be sent can be made different each time the condition is satisfied. For example, if the exact same message is transmitted repeatedly, the user may become accustomed to the message, and the effect of changing the user's psychological state may become less effective. Therefore, for example, a message is sent when there is a sudden interruption from another mobile object at one time, and a message is sent when there is a sudden interruption from another mobile object at a different time. are different messages. As a result, the user feels the freshness of each message and listens to the message each time, which prevents the effect of switching the psychological state from becoming weaker compared to when the same message is sent every time. So it's good.

(15) The situation in which the mobile body is observed by the observation means is any of the operation status from the user accepted by the mobile body, the operation status of the mobile body, and the surrounding situation of the mobile body. Or a device characterized by a combination of two or more.

In this way, it is possible to select the grounds for determining the situation when performing processing according to the observation results, or to select and combine them. This is advantageous because the situation of the moving object can be determined with high accuracy.

For example, it is preferable to use the operation status accepted by the mobile object from the user as the basis for determining the situation. This is good because it can detect situations such as sudden steering or sudden braking violations. Further, for example, the operational status of the moving body may be used as the basis for determining the situation. This is good because it can detect situations such as violations of no lights.

Further, for example, the surrounding situation of the moving object may be used as the basis for the situation judgment. This is good because it can detect situations such as being stuck in a traffic jam. Furthermore, it is advisable to combine these conditions in other ways. This is good because it enables determination even in situations where it cannot be determined accurately with one condition.

(16) An apparatus characterized in that the surrounding situation of the moving object is a situation based on a relationship between the moving object and other moving objects.

In this way, the message can be sent based on the relationship between the mobile unit and other mobile units. For example, you may be in a situation where you are being provoked by a vehicle following you that approaches you more than necessary, or you may unintentionally get too close to another vehicle in front of you due to frustration due to time constraints and the distance between the vehicles may be reduced. This is good because you will be able to send messages when you are close.

(17) An apparatus characterized in that the surrounding situation of the moving body is a situation based on a location where the moving body is moving.

In this way, the message can be sent based on the location where the mobile object is moving. For example, it is possible to send a message in a situation where a moving object is in a prohibited area or has already entered the area.

(18) An apparatus characterized in that the message is sent in a manner that can be detected even when the user is operating the mobile body.

This is good because the user can reliably perceive the message. While operating a moving object, for example, the user visually looks ahead or in the rear view mirror, grips the handle and rotates the handle using the sense of touch, or depresses the accelerator or brake.

Therefore, it is conceivable to send a message so that the user can detect it by using abilities other than the user's five senses that are used for such operations. For example, it is preferable to send a voice message so that it can be detected by the auditory senses of a user who is relatively unused to the operation. Additionally, it is also good to display a message on the display device.

(19) A program that causes a computer to function as the device according to any one of 1 to 18 above.

By doing so, the configurations described in (1) to (18) above can be realized by a computer.

Furthermore, the configuration described in any one of (1) to (18) above may be realized by a computer, but some or all of the configuration described in each of (1) to (18) above may be realized by a computer. It may also be realized by a computer in combination. In other words, a configuration in which each of the components described in (1) to (18) above is arbitrarily combined may be realized by a computer without changing the gist of the present invention.

According to the present invention, it is possible to affect the user's psychological state during driving without adding a dedicated measuring device for measuring the user's emotions.

Next, embodiments of the present invention will be described in detail with reference to the drawings.

<Exterior view of message sending device>
First, the appearance of the message sending device will be explained. As shown in FIG. 1, a message sending device 100 according to an embodiment of the present invention is detachably attached to a cradle 200, which is a member that holds the message sending device 100.

Here, the message sending device 100 is a device that affects the user's psychological state during driving by sending messages without adding a dedicated measuring device to measure the user's emotions. In the following description, such a message for influencing the user's psychological state during driving will be simply referred to as a "message." The message sending device 100 also has a function as a navigation device (PND).

On the other hand, the cradle 200 includes a cradle main body 210 that holds the message sending device 100, and a pedestal section 220 that supports the cradle main body 210 in an arbitrary posture at a predetermined position in the vehicle interior (such as the dashboard). There is. The pedestal section 220 is fixed to a dashboard or the like by suction using a suction cup provided on the bottom surface. The pedestal portion 220 and the cradle main body 210 are rotatably connected within a predetermined angular range via a connection mechanism such as a ball joint. Since it is a ball joint, the pedestal portion 220 and the cradle main body 210 rotate relative to each other within an arbitrary angular range in three-dimensional directions, and remain at an arbitrary angular position due to frictional resistance at the joint portion. Therefore, the message sending device 100 attached to the cradle main body 210 can also be placed in any position on the dashboard.

Then, the user can install the message sending device 100 together with the cradle 200 on the dashboard of the vehicle and use it as an in-vehicle device, or remove the message sending device 100 from the cradle 200 and use it as a portable device. can do.

Next, the equipment and parts included in the message sending device 100 will be explained. The message sending device 100 includes a flat rectangular case 150.

Furthermore, a touch panel 101 with a display function is arranged on the front surface of the case 150. The touch panel 100 is realized by a display section that performs display and a detection section that detects which part on the display section is touched.

Furthermore, notification LEDs 103 are provided on both sides of the front surface of the case 150 to notify the user.

Furthermore, an SD memory card slot section 105 and a drive recorder connection section 106 are provided on one side of the case 150.

An SD memory card 22 on which map data and the like are recorded is inserted into the SD memory card slot section 105.

Further, a drive recorder installed in the vehicle is connected to the drive recorder connection unit 106 via a cable (not shown). Then, an image of the surroundings of the vehicle captured by the drive recorder is input to the drive recorder connection unit 106.

Furthermore, a DC jack and an illuminance sensor 111 are provided on the back side (not shown).

The DC jack is for connecting a cigarette plug cord (not shown), and is connected to a cigarette socket of the vehicle via the cigarette plug cord to receive power supply. A battery (not shown) is provided inside the case 150, and the battery is charged with the power supplied from the DC jack, and when the power is no longer supplied from the DC jack, the operation is performed using the power charged in the battery. can do.

The illuminance sensor 111 is a sensor that measures the illuminance outside the case 150, and measures the illuminance of light outside the vehicle that enters the vehicle through the front window of the vehicle.

An OBD connection section 107 (not shown) and a USB terminal 108 (not shown) are provided on the side surface opposite to the side surface where the SD memory card slot section 105 and the drive recorder connection section 106 are provided.

The OBD connector of the vehicle is connected to the OBD connection portion 107 via a cable (not shown). Various types of information output from the connected OBD connector are input to the OBD connection section 107. The various types of information include, for example, information representing the vehicle speed, engine speed, steering angle, brake operation state, accelerator operation state, etc. of the vehicle.

Furthermore, by connecting to a personal computer via the USB terminal 108, software applications can be updated.

A button 102 is provided on the top surface of the case 150. More specifically, the button 102 includes three buttons from the left: a button 102a, a button 102b, and a button 102c.

Here, the button 102a is a message sending start/end button, the button 102b is a service guidance start/end button, and the button 102c is a power button.

When the button 102c is pressed while the power is off, the message sending device 100 starts the startup process. Then, when the message sending device 100 is activated, message sending and operation guidance are started. By pressing the button 102a or the button 102b, the user can end the sending of a message or the operation guidance, or restart it. Furthermore, when the button 102c is pressed while the message sending device 100 is activated and operating, the message sending device 100 transitions to a power-off state.

<Inside message sending device>
Next, each device and component inside the case 150 shown in FIG. 2 will be explained. It should be noted that overlapping explanations of each device/component shown in FIG. 1 will be omitted. Note that in FIG. 2, the button 102a, button 102b, and button 102c are collectively shown as a button 102.

First, inside the case 150, a speaker 104 is provided for sending messages and audio for operation guidance. Messages, voices, etc. transmitted by the speaker 104 are transmitted through a sound emitting hole provided in the case 150 so that the user can hear them.

Furthermore, the case 150 includes a GPS sensor 109 that receives a GPS signal and determines the current position of the message sending device 100.

Furthermore, a control unit 120 including a microcomputer 121 and a nonvolatile memory connected to the microcomputer 121 is provided inside the case 150. A microcomputer is realized by a computer that performs arithmetic processing. Further, the nonvolatile memory is realized by an EEPROM (Electrically Erasable Programmable Read-Only Memory).

In addition to the function of sending messages, the message sending device 100 of this embodiment also has a function of providing vehicle operation guidance, and these functions are stored in the storage section of the control section 120 as a program executed by a microcomputer included in the control section 120. The microcomputer included in the control unit 120 executes this to realize the process. Unless otherwise specified below, the described processing is executed by the microcomputer 121 included in the control unit 120 executing a program stored on the nonvolatile memory 122.

The control unit 120 also includes the various input devices (touch panel 101, buttons 102, SD memory card slot unit 105, drive recorder connection unit 106, OBD connection unit 107, USB terminal 108, GPS sensor 109, and illuminance sensor 111). etc.), and output devices (touch panel 101, notification LED 103, speaker 104, SD memory card slot section 105, USB terminal 108, etc.) to output predetermined information. Outputs warnings and messages. Further, the control unit 120 accesses the database 112 and the SD memory card 22 as necessary when performing predetermined processing. This predetermined processing is for executing each of the above functions.

The database 112 is a database used by the control unit 120, and is realized by flash memory.

Message information tables as shown in FIGS. 4-1 to 4-5 are registered in the database 112 at the time of shipment. The detailed contents of the message information table will be described later.

The database 112 also includes map information, a telephone number database that stores telephone numbers in association with location information and names of houses, businesses, facilities, etc. associated with the telephone numbers, and addresses and location information of the addresses. Information such as an address database stored in association with the vehicle, and a traffic rule database storing information related to traffic rules such as no-passing zones, lane information at intersections, no-passing information, and no entry are registered at the time of shipment.

After shipping, when adding a new message to the message information table, when adding new map information, etc., the database 112 can be updated through predetermined processing. This updating process can be performed, for example, by inserting an SD memory card storing additional data into the SD memory card slot section 105 and transferring the additional data from the SD memory card to the database 112. be. Further, this data update can be performed by using a personal computer or other external device connected via the USB terminal 108.

<Operation when sending a message>
Next, the operation when sending a message will be described with reference to the flowchart of FIG. 3 and the message information tables shown in FIGS. 4-1 to 4-5.

First, when the switch 24c is pressed, the microcomputer 121 in the control unit 120 that detects the press performs arithmetic processing based on the program stored in the nonvolatile memory 122, and each hardware in the message sending device 100 By controlling the wear, the operation guidance function is activated. Then, operation guidance is continued in parallel with each process in each step below (step S11).

Next, when the control unit 120 activates the message sending function in the same manner as the operation guidance function, it first refers to the table stored in the database 112.

As shown in Figures 4-1 to 4-5, the message information table includes the "situation" that sends the message, the "number" assigned to identify each situation, and the number of occurrences of each situation. Detection conditions and sending method, which are the detection conditions for detecting whether or not the detection conditions are met, and the specific method for determining whether the detection conditions are met, and the message to be sent when the detection conditions are met. It includes "sending message", "message sending timing" indicating the timing to send the message, and "message type" indicating the type of message.

In this embodiment, messages are sent based on the information contained in such a table. Specifically, if it is determined that a detection condition is satisfied based on the detection method included in the table, it is assumed that a situation corresponding to the detection condition has occurred, and the situation under which the situation occurred is calculated. An appropriate message is sent at a timing corresponding to the situation that occurs.

In order to perform such processing, the control unit 120 first inputs information input from the drive recorder connection unit 106, OBD connection unit 107, GPS sensor 109, illuminance sensor 111, etc., map information, etc., and information in the message information table. Based on the "detection condition and detection method", it is determined at a predetermined cycle whether any detection condition is satisfied (step S12, No in step S12).

In this regard, in this embodiment, a plurality of situations in which messages should be sent are assumed, as shown in FIGS. 4-1 to 4-5. The message information table includes a plurality of detection conditions and detection methods corresponding to these plurality of situations. However, since the purpose of the explanation here is solely to explain the flow of a series of processes performed by the control unit 120, the case where the situation No. 1 occurs will be explained as an example, and other situations will be explained. , will be explained in detail in the next item <Message information table>.

Here, the detection conditions for situation number 1 will be explained. First, the detection conditions and detection method for situation No. 1 are as shown in FIG. 4-1: "Circle 1 → Follow the preceding vehicle from the image of the drive recorder." Therefore, the control unit 120 analyzes the drive recorder video input via the drive recorder connection unit 106, and detects the preceding vehicle from within the video. Then, the detected preceding vehicle is followed.

Next, "Circle 2 → The condition is that the foot brake is detected from the regularly monitored OBD information as soon as a new vehicle is detected between the preceding vehicle and the vehicle being followed. , to detect sudden and forceful interruptions." Therefore, the control unit 120 continues to analyze the video of the drive recorder, and determines whether a new vehicle is detected between the vehicle and the preceding vehicle that is being followed. If a new vehicle is detected between the preceding vehicle that is being followed, the foot brake is inputted via the OBD connection unit 107 to determine whether or not the foot brake was depressed immediately before the detection. make decisions based on information about the behavior of

Here, the reason for determining whether or not the foot brake was depressed immediately before the detection of a new vehicle will be explained. Even if there is an interruption by a new vehicle, if this has been forewarned by a turn signal, etc., the user will have adjusted the following distance etc. before the interruption, so the foot brake should be applied immediately before the interruption. There is no need to step on it. However, in the case of such a sudden and forcible interruption without prior notice, the user hastily steps on the foot brake immediately before the interruption.

In other words, if the footbrake is depressed in the immediate vicinity of the detection of a new vehicle, a sudden and forceful interruption will occur, causing the user to feel irritated or impatient, which is inappropriate for driving. It is thought to have a psychological state.

Therefore, we have created a message that works on the user's psychology and switches the user's psychological state to a calm state suitable for driving, using the detection condition that the foot brake has been depressed immediately before the detection of a new vehicle. Send out.

In this way, if the foot brake is depressed immediately before the detection of a new vehicle, the detection condition is satisfied (Yes in step S12). In this case, the control unit 120 proceeds to the next step S13.

In step S13, the control unit 120 selects a message to send. The message to be sent is selected from among the messages to be sent that correspond to the detection conditions that have been met this time. As shown in Figure 4-1, the messages that are sent out corresponding to the detection conditions that were met this time include things like "You're surprised! Calm down! Calm down" and "You're driving dangerously! Please do something in a hurry." There are multiple messages such as "I wonder if he was there!" In this case, one of the plurality of messages is randomly selected. If a message is selected from a plurality of messages in this way, a different message will be sent each time even if the same detection condition is satisfied, which is good because the user will not get bored with the messages.

Next, the selected message is sent out, but if the detection condition is met, sending out the immediate message may have an adverse effect on the user's driving. For example, if there is a sudden and forcible interruption, the user must first quickly adjust the vehicle speed and maintain a sufficient distance between vehicles to maneuver out of the dangerous situation. Nevertheless, if a message is sent immediately in the event of a sudden and forcible interruption, the user may be distracted by the message and may not be able to concentrate on the operation.

In this way, if the user notifies the user while the danger is being dealt with or at the moment when the driver is dealing with the danger, it may turn out to be dangerous, so in this embodiment, the message is sent after the danger has been dealt with (when the driver has calmed down). will be sent.

However, depending on the situation, there may be no problem or it may be preferable to send the message immediately if the detection conditions are met. For example, in the situation shown in Figure 4-2, number 6, ``I have shortened the following distance out of frustration due to time constraints,'' send an immediate message to quickly secure the following distance. It is preferable to encourage people to do what they should.

In other words, if the situation is different, the timing at which the message should be sent will be different. Therefore, the message information table is provided with a message sending timing item, and the message is sent when the message sending timing is reached.

In this regard, the timing of sending messages can be roughly divided into two types: sending messages when the user's feelings have calmed down, and sending messages when the user's feelings have calmed down. It can be divided into two types: sending based on conditions. Therefore, in step S14, it is determined which of the above two timings corresponds to the message sending timing corresponding to the satisfied detection condition.

Here, if the message sending timing corresponding to the satisfied detection condition is not "when things have calmed down" (No in step S14), the process advances to step S15. For example, if the detection conditions for the situation No. 6 in Figure 4-2, ``I shortened the following distance out of frustration due to time constraints,'' the message sending timing is set to ``When detected.'' "immediate notification". In such a case, the process advances to step S15.

Then, in step S15, it is determined whether the message sending timing has come (step S15). Here, for example, if the message sending timing is "immediate notification upon detection", the message sending timing is reached at the time of detection, so the process advances to step S19 (Yes in step S15). On the other hand, for example, if the message transmission timing is "sent after passing an intersection", it is determined that the vehicle has passed through the intersection based on the map information stored in the database 112 and the position information measured by the GPS sensor 109. If it is determined that the vehicle has passed the intersection (Yes in step S15), the process advances to step S19 (Yes in step S15).

In step S19, the control unit 120 performs control to send the message selected in step S13, and based on this control, the message is sent from the speaker 104 or the touch panel 101 (step S19).

For example, the voice data of the message is stored in the database 112, and the voice data is reproduced and output from the speaker 104 at the time of transmission, thereby transmitting the voice. Alternatively, the message is stored in the database 112 as text data, and a voice corresponding to the text data is generated by voice synthesis, and the voice is output from the speaker 104. Further, for example, since a message is stored as text data in the message information table in the database 112, the text data is displayed on the touch panel 101. By doing so, the user can perceive the contents of these messages.

Here, an example of display on the touch panel 101 when text data is displayed on the touch panel 101 is shown in FIG. During normal operation guidance, a map and various information for operation guidance are displayed on the screen, as shown in the upper part of FIG. 5 as "(a) Normal time". The user drives while referring to this display. Here, when some detection condition is satisfied and it is time to send a message, text corresponding to the message is displayed as shown in the lower part of FIG. 5 as "(b) Normal time". A user can perceive the content of a message by referring to such a message.

On the other hand, if the message sending timing corresponding to the detection condition satisfied in step S12 is "when things have calmed down" (Yes in step S14), the process advances to step S16. For example, the message sending timing corresponding to the situation number 1 is "sending when things calm down" as shown in FIG. 4-1. Therefore, in this case, the process advances to step S16.

Then, in steps S16 to S18, it is determined whether the user operating the vehicle has escaped danger and is in a calm state based on the behavior of the vehicle operated by the user.

Specifically, the control unit 120 first checks whether the value of the vehicle deceleration acceleration input to the OBD connection unit 107 is less than or equal to a predetermined threshold (step S16). Here, the predetermined threshold value is a threshold value measured when the vehicle is in a safe state. In other words, a value other than the deceleration acceleration measured during sudden braking is set as the predetermined threshold value.

If the value of the deceleration acceleration of the vehicle input to the OBD connection unit 107 is less than or equal to the predetermined threshold value, the process proceeds to step S17 (Yes in step S16). On the other hand, if the value of the deceleration acceleration of the vehicle input to the OBD connection unit 107 exceeds a predetermined threshold value, it is considered that the vehicle is in a dangerous situation where it is braking suddenly, so the determination in step S16 is repeated. (No in step S16).

Next, the control unit 120 determines whether the steering angle of the steering wheel is within a predetermined range based on the information representing the steering angle of the steering wheel inputted from the OBD connection unit 107 (step S17). Here, the predetermined range is a value representing the range measured when the vehicle is in a safe state. In other words, the predetermined range is a range of steering angles that are not measured when the steering wheel is suddenly turned.

If the steering angle of the steering wheel is within a predetermined range based on the information representing the steering angle of the steering wheel inputted from the OBD connection unit 107, the process advances to step S18 (Yes in step S17). On the other hand, if the steering angle of the steering wheel is not within the predetermined range, the process returns to step S16 (No in step S17).

Next, the control unit 120 determines whether the brake and accelerator operations are calm based on the information regarding the brake and accelerator operations input from the OBD connection unit 107 (step S18). The control unit 120 determines that the accelerator operation is calm when the accelerator opening input from the OBD connection unit 107 is within a predetermined range. Furthermore, if the brake pedal has not been pressed down continuously for a predetermined period of time, it is determined that the brake operation is calm.

If it is determined that the brake and accelerator operations are stable based on the information regarding the brake and accelerator operations input from the OBD connection unit 107, the process advances to step S19 (Yes at step S18). On the other hand, if it cannot be determined that the brake and accelerator operations are calm based on the information regarding the brake and accelerator operations input from the OBD connection unit 107, the process returns to step S16 (No in step S18).
.

Here, the case where the process proceeds to step S19 in this way means that the deceleration acceleration is less than or equal to the predetermined value, so sudden braking is not in progress (Yes in step S16), and the steering angle of the steering wheel is within the predetermined range. For this reason, the driver is not turning the steering wheel suddenly (Yes in step S17), and both the brake operation and the accelerator operation are calm (Yes in step S18).

Therefore, the behavior of the vehicle operated by the user is stable, and it is considered that the user feels calm. In other words, the timing for sending the message is "when things have calmed down."

Therefore, the control unit 120 performs control to transmit the selected message in step S13, and the speaker 104 and the like execute the message transmission in accordance with this control. Note that the more specific content of the process in step S19 is the same as the content of the process in step S19 that is performed in the case of Yes in step S15 described above, so a repeated explanation will be omitted here.

As described above with reference to FIG. 3, in this embodiment, if it is determined that the detection condition is satisfied based on the detection method included in the message information table, a situation corresponding to the detection condition occurs. An appropriate message is sent under the circumstances in which such a situation has occurred at a timing corresponding to the situation that has occurred.

This has the effect that the sent message can influence the psychological state of the user during driving. Further, in this embodiment, the above-described processing can be realized using information input via the OBD connection unit 107 and information measured by the GPS sensor 109 and the illuminance sensor 111. Therefore, there is an effect that there is no need to add a dedicated measuring device for measuring the user's emotions in order to send a message.
<Message information table>
Next, each situation included in the message information table will be explained in more detail.

First, the situation No. 1 is a situation in which a "sudden and forcible interruption" occurs.

The detection conditions and detection method for this situation are "Circle 1 → Follow the preceding vehicle from the drive recorder video." Therefore, the control unit 120 analyzes the video input from the drive recorder connection unit 106. , detects a preceding vehicle in the video and follows the detected preceding vehicle. Then, "Round 2 → Just when a new vehicle was detected between the vehicle in front and the vehicle being followed, it was detected that the foot brake was pressed and a sudden deceleration was detected from the regularly monitored OBD information. Therefore, the control unit 120 continues to analyze the video of the drive recorder and detects a new vehicle between the preceding vehicle and the preceding vehicle. It is determined whether or not the If a new vehicle is detected between the preceding vehicle and the vehicle being followed, the foot brake is depressed in the immediate vicinity of the detection based on information regarding the behavior of the foot brake input to the OBD connection unit 107. If it can be determined that a sudden deceleration/acceleration is detected, it is determined that the detection condition is satisfied, and a sudden forcible interruption is detected.

The message to send in this case is "You're surprised! Calm down! Calm down."
It is. In this way, by empathizing with the user and sending a message urging the user to calm down, the user's psychological state is switched to one appropriate for driving.

Other messages sent include, ``You're driving dangerously! I wonder if you were in a hurry!'' or ``Were you in a hurry because of something urgent? There are many different people. Please drive carefully and calmly!" In this way, by considering the circumstances of the other party who has interrupted the user, a message is sent that causes the user to change his/her perspective, thereby switching the user's psychological state to one appropriate for driving.

Another message that is sent out is, ``It's scary! There are strange people in this world! It's dangerous, so don't approach them and keep your distance!'' In this way, by sending a message that represents the user's thoughts, the user's psychological state is switched to one appropriate for driving.

Immediately after receiving a sudden and forceful interruption, the user is in a dangerous situation, so the message should be sent when the message has calmed down.

Next, the situation No. 2 is a situation in which "tailoring from a following vehicle" occurs.

The detection conditions and detection method for this situation are "Circle 1 → Always monitor the approach of the vehicle behind from the image of the back monitor of the drive recorder." Therefore, the control unit 120 receives input from the drive recorder connection unit 106. By analyzing the video, it monitors whether a vehicle behind it is approaching. Then, since "circle 2 → detects tailgating from the following vehicle on the condition that the approach of the following vehicle is detected by monitoring", the control unit 120 determines that the following vehicle has a predetermined inter-vehicle distance. If the distance is less than that, it is determined that the detection conditions are met, and tailgating from the following vehicle is detected.

The message sent in this case is ``A car that appears to be in a hurry is approaching. Adults, let's give way to the insane car coming from behind!'' In this way, by sending a message that motivates the user who drives the vehicle, the user's psychology can be changed.

Since the state of being agitated is a dangerous state, the timing of sending the message is to "send when the situation has calmed down."

Next, the situation No. 3 is a situation in which "I was pressed for time and got stuck in a traffic jam on an expressway."

The detection conditions and detection method for this situation are "Circle 1 → Detect the approach of a car in front using the image from the drive recorder", so the control unit 120 analyzes the image input from the drive recorder connection unit 106. , monitor whether the vehicle in front is approaching. Then, "circle 2 → monitor the vehicle speed of the own vehicle from OBD information, and detect that the vehicle is stuck in a traffic jam on the condition that slowing down is detected." Therefore, the control unit 120 controls the vehicle speed input from the OBD connection unit 107. When the vehicle speed falls below a predetermined speed, it is determined that the detection conditions are met and tailgating from a following vehicle is detected.

In this case, the message to be sent is, ``Looks like there's a traffic jam! It can't be helped! Let's get going!'' In this way, by sending a message that calmly explains the situation to the user driving the vehicle, User psychology can be changed.

Another message sent in this case is "It looks like everyone is going in the same direction! Here we go!" In this way, the user's psychology can be changed by sending a message that empathizes with the feeling of "I'm in trouble" of the user driving the vehicle.

Since the driver is stuck in a traffic jam and has already slowed down and is not in a dangerous situation, the message sending timing is "send immediately when detected."

Next, the situation No. 4 is a situation in which "you cannot enter a road with heavy traffic" has occurred.

The detection conditions and detection method for this situation are as follows: ``Circle 1 → From map information and measured position information, check that the vehicle is stopped at a confluence point such as an intersection.Detect the flow of vehicles ahead using images from the drive recorder. Therefore, the control unit 120 confirms that the vehicle is stopped at a confluence point such as an intersection, based on the map information stored in the database 112 and the position information measured by the GPS sensor 109. Additionally, by analyzing the video input from the drive recorder connection unit 106, the flow of the vehicle ahead is detected. Then, when the vehicle is stopped at a merging point such as an intersection and there is a flow of traffic ahead, it detects that the blinker is blinking from the OBD information, and if it is an AT vehicle, the shift position is changed. Confirm from the OBD information that it is not "P", "R" or "N". It also confirms that the driver is pressing the foot brake, and if the vehicle does not move for several tens of seconds in this state, it detects that the vehicle is waiting to enter the road and cannot enter the road. ” Therefore, based on the information input from the OBD connection unit 107, the control unit 120 determines whether the turn signal is blinking, the shift position is “D”, etc., and the foot brake is depressed. If the vehicle does not move for several tens of seconds, it is determined that the detection conditions are met, and tailgating from a following vehicle is detected.

The messages sent in this case are ``Calm down and move into the flow of traffic!'' and ``Don't rush! Don't rush!''. In this way, by sending a message to calm the user driving the vehicle, the user's psychology can be changed.

Another message sent in this case is "Take a deep breath and change your mind!" In this way, by sending a message urging the user who drives the vehicle to take a deep breath, the user's psychology can be changed.

Since it is stopped and not in a dangerous state, the message sending timing is "immediately sent when detected."

Next, the situation No. 5 is a situation in which "pedestrians and bicycles walking in front of me on a narrow road do not notice my car approaching from behind and have difficulty passing it."

The detection conditions and detection method for this situation are "Circle 1 → Check that the road is narrow and not an expressway or national highway from the map information and the measured position information", so the control unit 120 stores the information in the database 112. From the map information provided and the position information measured by the GPS sensor 109, it is confirmed that the vehicle is on a narrow road that is not an expressway or national highway. Then, "Circle 2 → Detect a person in front from the image of the drive recorder." Therefore, the control unit 120 detects the presence of a person in front by analyzing the image input from the drive recorder connection unit 106. do. Then, the control unit 120 receives input from the OBD connection unit 107 because "circle 3 → Monitor the vehicle speed from OBD information. It is detected that it is difficult to pass under the condition that the vehicle has been traveling at a slow speed for several tens of seconds." Based on the vehicle speed determined by the vehicle, if the vehicle continues to travel at a slow speed for several tens of seconds, it is determined that the detection conditions are met, and it is detected that the vehicle cannot pass easily.

The messages sent in this case are: ``I'm in trouble! I don't want to threaten you, so I hope you realize it soon!'', ``Cars are stronger than people, so you don't want to startle people!'', and ``Don't be surprised!'' , ``I hope you realize it soon! Look back, look back!'' etc. In this way, by sending a message that empathizes with the user driving the vehicle, the user's psychology can be changed.

Another message sent in this case is "You are a kind driver! Let's remind you kindly!" In this way, by sending a message praising the user who drives the vehicle, the user's psychology can be changed.

Since the vehicle cannot pass and is moving slowly and is not in a dangerous condition, the timing for sending the message is "send immediately when detected."

Next, the situation No. 6 is a situation in which "the distance between vehicles was shortened due to frustration or impatience due to time constraints."

The detection conditions and detection method for this situation are "Circle 1 → Monitor the distance between the vehicle and the vehicle ahead from the drive recorder image." Therefore, the control unit 120 analyzes the image input from the drive recorder connection unit 106. This monitors the distance between you and the vehicle in front. Then, since "Circle 2→Monitor vehicle speed from OBD information.", the control section 120 monitors the vehicle speed input from the OBD connection section 107. In addition, "Circle 3 → Detects that the following distance has been shortened on the condition that the necessary inter-vehicle distance has not been secured for the current vehicle speed" The control unit 120 detects the monitoring results of Circles 1 and 2. If it is determined that the necessary inter-vehicle distance is not secured for the current vehicle speed based on the above, it is determined that the detection condition is satisfied and it is detected that the inter-vehicle distance has been shortened.

In this case, the messages sent are: ``It looks like the following distance is a little close! It might be better to maintain a safer distance. Let's move on without rushing!'' and ``It's close! It's dangerous! It's dangerous. Let's keep a safe distance between cars!". In this way, by sending a message that concerns the safety of the user driving the vehicle, the user's psychology can be changed.

Since it is necessary to prompt the driver to quickly maintain a distance between vehicles, the timing for sending the message is "sent immediately upon detection."

In each of the situations explained above, the message type is "mental", and messages that represent the user's thoughts, empathize with the user's thoughts, or change the user's perspective are sent. By doing so, the user's psychological state is switched from a state inappropriate for driving to a state appropriate for driving.

On the other hand, the message type is "violation", which will be explained below, and when the user's driving violates traffic rules stipulated by laws and regulations, a message to that effect is sent to the user. As a result, the psychological state of a user who commits a violation while in a psychological state inappropriate for driving, such as being lax, is changed to a psychological state appropriate for driving, such as driving while keeping traffic rules in mind. Switch. Furthermore, if the user does not know or has forgotten the traffic rules, it is possible to make the user aware of the existence of the traffic rules.

Next, the situation No. 7 is a situation in which a "traffic classification violation (going straight or turning left from a right turn lane would be a traffic classification violation)" has occurred.

The detection conditions and detection method for this situation are "Circle 1 → The driving lane is detected from the map information and the measured position information, and a violation is detected on the condition that the intersection is not driven in the specified direction of travel." , the control unit 120 detects the driving lane from the map information and traffic rule database stored in the database 112 and the position information measured by the GPS sensor 109, and moves the intersection to the specified direction of travel. If the driver does not run to the vehicle, it is determined that the detection conditions are met, and a traffic classification violation is detected.

The messages sent in this case are, ``You're driving in the wrong lane.'' or ``Oh, I think you're driving in the wrong lane. I'm glad you didn't get into an accident. Let's be careful next time!'' . In this way, by sending a message to the user who is driving the vehicle notifying them that they have violated the traffic rules, the user's psychological state can be changed to a state appropriate for driving by keeping the traffic rules in mind. Switch. Furthermore, if the message is the latter one, it is a message that cares about the user, so it is possible to calm the user's psychological state.

While passing through an intersection, the driver must concentrate on driving, so the timing for sending the message is "sent after passing the intersection".

Next, the situation No. 8 is a situation in which a "road closure/entry violation" has occurred.

The detection conditions and detection method for this situation are as follows: ``Circle 1 → Create a database of road closure and entry prohibited information in the map information, and use the measured position information to detect violations on the condition that you enter a road where entry is prohibited. ” Therefore, the control unit 120 was able to detect that the vehicle had entered a prohibited road based on the map information and traffic rule database stored in the database 112 and the position information measured by the GPS sensor 109. In this case, it is determined that the detection condition is satisfied, and a road closure/entry violation is detected.

In this case, the message sent is ``Entry is prohibited on this road.'' or ``Entry is prohibited here, so let's change the route!''. In this way, by sending a message to the user who is driving the vehicle notifying them that they have violated the traffic rules, the user's psychological state can be changed to a state appropriate for driving by keeping the traffic rules in mind. Switch. In addition, the latter message notifies the user of specific measures to avoid the violation, so it not only reassures the user but also informs the user how to avoid the violation. It will be possible to notify the

In the case of a road closure/entry violation, it is necessary to promptly change the route, so the message sending timing is "immediate notification when detected."

Next, the situation No. 9 is a situation in which an "overtaking violation" has occurred. The detection conditions and detection method for this situation are "Circle 1→Map information includes road section information where overtaking is prohibited in a database." As described above with reference to FIG. 2, in the database 112, A traffic rule database containing such information is stored. Then, ``Circle 2 → A violation will be imposed on the condition that the lane is recognized and a change to a lane where overtaking is prohibited is detected using the measured position information, OBD information of the car's steering angle information, and video from the drive recorder. Detection.'' Therefore, the control unit 120 uses information included in the traffic rule database, position information measured by the GPS sensor 109, steering angle information input from the OBD connection unit 107, and video input from the drive recorder connection unit 106. If the system detects a change to a lane where overtaking is prohibited based on the above, the system determines that the detection conditions are met and detects an overtaking violation.

The message sent in this case is "Overtaking is prohibited at this point." In this way, by sending a message to the user who is driving the vehicle notifying them that they have violated the traffic rules, the user's psychological state can be changed to a state appropriate for driving by keeping the traffic rules in mind. Switch.

Immediately after overtaking, it is necessary to adjust the vehicle speed, etc., so the message should be sent when the vehicle has calmed down.

Next, the situation No. 10 is a situation in which a "violation of failure to stop at a railroad crossing, etc." has occurred.

The detection conditions and detection method for this situation are "Circle 1 → Detect passing through a railroad crossing from map information and measured position information." Therefore, the control unit 120 uses the map information and traffic rules stored in the database 112. Based on the database and position information measured by the GPS sensor 109, it is detected that the vehicle passes through a railroad crossing. Then, "Maru 2 → Detects vehicle speed and stepping on the foot brake using OBD information, and monitors temporary stops. Violations are detected as long as it is confirmed that the vehicle is not stopped." The unit 120 monitors the vehicle speed and foot brake operation status input from the OBD connection unit 107, and if it is confirmed that the vehicle has not stopped temporarily, it determines that the detection condition is satisfied and issues a violation such as failure to stop at a level crossing. Detect.

The message sent in this case is "Let's stop temporarily before the railroad crossing!" In this way, by sending a message to the user who is driving the vehicle notifying them that they have violated the traffic rules, the user's psychological state can be changed to a state appropriate for driving by keeping the traffic rules in mind. Switch.

Since the driver must concentrate on driving while passing through a level crossing, the timing for sending the message is "sending dirt after passing through a level crossing."

Next, the situation numbered 11 is a situation in which a "temporary stop violation" occurs.

The detection conditions and detection method for this situation are "Circle 1 → Confirm that the vehicle passes the temporary stop point based on the map information, traffic rule database information, and measured position information." Therefore, the control unit 120 stores the data in the database 112. It is confirmed that the vehicle passes the temporary stop point based on the map information and information on the traffic rule database, and the position information measured by the GPS sensor 109. Then, "Maru 2 → Detects vehicle speed and stepping on the foot brake using OBD information, and monitors temporary stops. Violations are detected as long as it is confirmed that the vehicle is not stopped." The control unit 120 monitors the vehicle speed and foot brake operation status input from the OBD connection unit 107, and determines that the detection condition is satisfied when it is confirmed that the vehicle is not temporarily stopped; Detects violations such as failure to stop at a railroad crossing.

The message sent in this case is "The game was not paused." In this way, by sending a message to the user who is driving the vehicle notifying them that they have violated the traffic rules, the user's psychological state can be changed to a state appropriate for driving by keeping the traffic rules in mind. Switch.

Since it is necessary to concentrate on driving especially near the point where a temporary stop is required, the timing for sending the message is "sent when the vehicle has calmed down."

Next, situation number 12 is a violation of the duty to proceed safely at an intersection (obligation to be careful of cars and pedestrians when entering or passing an intersection, and proceed at the safest speed and method possible). This is a situation that occurred.

The detection conditions and detection method for this situation are "Circle 1 → Detect that a vehicle is about to enter an intersection based on map information and position information." Therefore, the control unit 120 uses the map information stored in the database 112. Based on the position information measured by the GPS sensor 109, it is detected that the vehicle is about to enter the intersection. Then, "Maru 2 → The steering wheel operation, brake, accelerator, direction indication, and speed when entering the intersection are monitored from OBD information, and a violation is detected if a lack of caution is detected", so the control If the unit 120 detects that the user has neglected to pay attention to maneuvering based on various information input from the OBD connection unit 107, the unit 120 determines that the detection condition is satisfied and detects a violation of the duty to proceed safely at the intersection. For example, if it detects that you have suddenly turned the steering wheel, applied the brakes suddenly, entered an intersection at a speed higher than a predetermined speed without releasing the accelerator, or failed to give directions, It is determined that the detection condition is satisfied.

The message sent in this case differs depending on the cause of the detection condition being met. For example, if the detection condition is met because the vehicle entered an intersection at a speed higher than a predetermined speed without loosening the accelerator, it will send a message saying, ``Before and after the intersection, please drive at a slightly slower speed.'' Furthermore, if the detection condition is met because the driver neglected to give directions, a message is sent saying, "No directions were given when turning at an intersection."

In this way, by sending a message to the user who is driving the vehicle notifying them that they have violated the traffic rules, the user's psychological state can be changed to a state appropriate for driving by keeping the traffic rules in mind. Switch.

While passing through an intersection, the driver must concentrate on driving, so the timing for sending the message is "sent after passing the intersection".

Next, the situation number 13 is called ``Sudden braking prohibition violation (sudden stopping or sudden reduction of speed for no reason is prohibited except to prevent danger, but sudden braking is performed). This is a situation in which the following occurs.

The detection conditions and detection method for this situation are "circle 1→OBD brake operation information is monitored, and when the brake is stepped on, the strength of the deceleration acceleration at that time is measured." Therefore, the control unit 120 detects the OBD. Based on the brake operation information and deceleration acceleration input from the connection unit 107, when the brake is stepped on, the strength of the deceleration acceleration at that time is measured. Then, "Circle 2 → When the deceleration acceleration exceeds the threshold, a violation is detected on the condition that there is no obstacle in front of the drive recorder." Therefore, the control unit 120 analyzes the video input from the drive recorder connection unit 106 even if the deceleration acceleration exceeds the threshold, that is, even if sudden braking is performed, and if there is no obstacle in front, , it is determined that the detection conditions are met, and a violation of the sudden braking prohibition is detected.

The messages sent in this case are ``Be careful of sudden braking!'' and ``There appear to be no obstacles ahead.'' In this way, by sending a message to the user who is driving the vehicle notifying them that they have driven in a manner that violates the traffic rules, the user's psychological state can be adjusted to reflect the driver's mental state, which is appropriate for driving while keeping the traffic rules in mind. Switch to a psychological state.

Immediately after applying sudden braking, the situation is dangerous, so the message should be sent when the situation has calmed down.

Next, the situation number 14 is ``Violation of slow speed area (when you proceed without slowing down when passing a place where you should slow down, such as a road where you should slow down as specified by road signs, or an intersection where it is difficult to see left and right). )" has occurred.

The detection conditions and detection method for this situation are as follows: Circle 1: Based on map information, traffic rule database information, and measured position information, when passing a road where you should drive slowly, monitor the vehicle speed information on the OBD and drive slowly. A violation is detected on the condition that the vehicle is not traveling at a speed of If it is detected that the vehicle is passing through a road where the vehicle is supposed to travel, and the vehicle speed input from the OBD connection unit 107 is not the slow speed, it is determined that the detection condition is met and a slow speed violation is detected. .

In this case, the message sent is ``Drive slowly at intersections that are difficult to see or where there are slow speed signs!''. In this way, by sending a message to the user who is driving the vehicle notifying them that they have driven in a manner that violates the traffic rules, the user's psychological state can be adjusted to reflect the driver's mental state, which is appropriate for driving while keeping the traffic rules in mind. Switch to a psychological state.

Roads where drivers should drive slowly are places where they should especially concentrate on driving, so the timing of sending the message is "send when things have calmed down."

Next, the situation numbered 15 is a situation in which a "violation of no lights" has occurred.

The detection conditions and detection method for this situation are "circle 1 → Detect that it is necessary to turn on the lighting from the brightness level of the sunlight sensor", so the control unit 120 detects the brightness measured by the sunlight sensor 111. If the level is a predetermined threshold, it is detected that it is necessary to turn on lights such as headlights, small lights, and taillights. Then, ``Circle 2 → Detects whether the lights are ON/OFF from OBD information, and despite the brightness that requires the lights to be turned on, the violation is based on the condition that the lights have been driven for a while with the lights OFF. Based on the lighting status input from the OBD connection unit 107, the control unit 120 detects whether the lighting has been driven for a while with the lighting turned off, despite the brightness that requires the lighting to be turned on. In this case, it is determined that the detection conditions are met, and a violation of no lights is detected.

The messages sent in this case are ``It's getting dark. Let's turn on the lights!'' and ``Can you see ahead now?'' In this way, by sending a message to the user who is driving the vehicle notifying him/her that he or she is violating traffic rules, the user's psychological state can be adjusted to be appropriate for driving by keeping the traffic rules in mind. Switch to a psychological state. In addition, if the message is the former one, the user can be notified of a specific response method. Furthermore, if the message is the latter, it can be of concern to the user.

Since it is not appropriate to operate the light switch when the driving condition is not calm, the timing for sending the message is "sent when the vehicle is calm." Note that it is possible that things are calming down now, so the expression "sending out" is used when things are calming down, rather than when things are calming down. In the case of the sending timing of sending out when the message calms down like this message, it is assumed that the determination in step S14 is Yes.

Next, the situation No. 16 is a situation in which a "violation of failure to signal (when the timing of turning on the turn signal when turning right or left is too late, or when changing course without giving a direction signal)" has occurred. .

The detection conditions and detection method for this situation are "Circle 1 → Check that the intersection will be passed from the map information and the measured position information." Therefore, the control unit 120 uses the map information stored in the database 112, Based on the position information measured by the GPS sensor 109, it is detected that the vehicle passes through an intersection. Then, "Rudder angle from Maru 2 → OBD information and left and right turn signal information are regularly monitored, and violations are detected if the direction indicators are not operated properly." Based on the steering angle input from the OBD connection unit 107 and the information on the left and right turn indicators, the unit 120 determines that the detection condition is satisfied when the direction indicator is not operated appropriately, and the following Detects tailwinds from cars.

Specifically, if the right turn signal is flashed, but the steering angle of the steering wheel indicates that the driver has turned left, it is determined that the detection condition is satisfied because the turn signal was not operated appropriately. The message sent in this case is "You have turned in the opposite direction of the turn signal."

Further, even if the right turn signal is not flashing, but the steering angle of the steering wheel indicates that the vehicle has turned right, it is determined that the turn signal was not operated appropriately.
The message sent in this case is "No direction instructions were given."

Furthermore, even if the right turn signal is flashed, but only after the right turn has been completed, it is determined that the turn signal was not operated appropriately.
The message sent in this case is "It seems that the timing of issuing direction instructions was too late."

In either case, by sending a message to the user who is driving the vehicle notifying them that they have acted in a way that violates the traffic rules, the psychological state of the user is determined to encourage them to drive with the traffic rules in mind. Switch to a psychological state appropriate for driving.

Immediately after making a right or left turn, the driver should especially concentrate on driving, so the timing for sending the message is to "send when things have calmed down."

Next, situation number 17 is ``Violation of signaling restrictions (failure to follow the timing and method of signaling specified by government ordinance, or when an act that requires a signal such as a left turn, right turn, or turn is completed) This is a situation in which a person continues to give the signal even though the person should have stopped giving the signal, etc.).

The detection conditions and detection method for this situation are the same as those for situation No. 16 described above. That is, when the detection condition number 16 is satisfied, the detection condition of this situation is also satisfied at the same time. In other words, when one detection condition is satisfied, two violations occur simultaneously. However, the user only needs to understand one point: that it is necessary to appropriately indicate directions for turning right and turning left. Therefore, in such a case, one message is sent. For this purpose, the message to be sent and the message sending timing are the same as in situation number 17. In this way, if the same message is sent once instead of twice in a row, the user will not have to hear the same message multiple times in a row.

Next, the situation No. 18 is a situation in which a "minimum speed violation (when driving at low speed on an expressway, etc.)" has occurred.

The detection conditions and detection method for this situation are "Circle 1 → Determine whether the road the vehicle is traveling on is an expressway, etc. from the map information, traffic rule database, and measured position information." Therefore, the control unit 120 determines that the vehicle is currently traveling on an expressway based on the map information and traffic rule database stored in the database 112 and the position information measured by the GPS sensor 109. If it can be determined, a violation will be detected if the minimum speed is less than the court speed (50 km for expressways with two or more lanes) from the vehicle speed obtained at regular intervals from Maru 2 → OBD. ” Therefore, the control unit 120 monitors the vehicle speed input from the OBD connection unit 107, and when the vehicle speed falls below the predetermined legal speed, it determines that the detection condition is met, and prevents the following vehicle from swerving. Detect.

The message sent in this case is "Your speed is decreasing. Please be careful of the vehicle coming from behind." In this way, by sending a message to a user driving a vehicle notifying them that they have committed an act that violates traffic rules, the user's psychological state can be adjusted to the appropriate state of mind for driving by keeping the traffic rules in mind. Switch to state. Furthermore, the message "Please be careful of cars coming from behind" makes it possible to teach the user specific points to be careful of and to be considerate of the user.
Since it is necessary to quickly increase the speed, the message sending timing is "sent immediately upon detection."

Next, the situation numbered 19 is a situation in which "overspeeding" occurs.

The detection conditions and detection method for this situation are "Circle 1 → Determine the speed limit of the road on which the vehicle is traveling from the map information, the traffic rule database, and the measured position information." Therefore, the control unit 120 uses the database 112 The speed limit of the road on which the vehicle is currently traveling is determined based on the map information and traffic rule database stored in the system and the position information measured by the GPS sensor 109. Then, since "circle 2 → monitor the vehicle speed obtained from the OBD at regular intervals, and detect a violation on the condition that the speed limit has been exceeded", the control unit 120 controls the vehicle speed input from the OBD connection unit 107. If the vehicle speed exceeds the speed limit, it is determined that the detection conditions are met and tailgating from a following vehicle is detected.

The message sent in this case is "You are going too fast. Please be careful." In this way, by sending a message to a user driving a vehicle notifying them that they have committed an act that violates traffic rules, the user's psychological state can be adjusted to the appropriate state of mind for driving by keeping the traffic rules in mind. Switch to state. In addition, the message "Please be careful" allows the user to be considerate.
Since it is necessary to quickly increase the speed, the message sending timing is "sent immediately upon detection."
Next, the situation numbered 20 is a situation in which a "sudden steering wheel" occurs.

The detection conditions and detection method for this situation are as follows: ``Monitor the steering angle information and acceleration information of the steering wheel obtained from the OBD at regular intervals, and when the steering wheel steering angle exceeds the steering angle threshold angle and the acceleration exceeds the steep steering threshold. Therefore, the control unit 120 monitors the steering wheel steering angle information and acceleration information input from the OBD connection unit 107, and detects the violation if the steering angle exceeds the steering angle threshold angle. When the acceleration exceeds the sharp steering threshold, it is determined that the detection condition is satisfied, and the sudden steering is detected.

The message sent in this case is, "It is dangerous to turn the steering wheel suddenly. Please slow down before operating the steering wheel!" In this way, by sending a message to the user who is driving the vehicle notifying them that they have committed an act that violates the traffic rules, the user's psychological state can be adjusted to the appropriate level for driving by keeping the traffic rules in mind. Switch to a psychological state. In addition, it is possible to alert the user to the message "It is dangerous to turn the steering wheel suddenly."
Since the driver is in a dangerous situation after turning the steering wheel suddenly, the timing for sending the message should be "sent when things have calmed down."

<Add message>
The sending messages included in the message information table described above are those stored in the database 112 or the nonvolatile memory 122 when the message sending device 100 is shipped. In this regard, the message sending device 100 can add new messages in accordance with user preferences and the like after the message sending device 100 is shipped.

To add a message, an SD memory card storing voice data or text data corresponding to the message is inserted into the SD memory card slot section 105, and the control section 120 reads the data from the SD memory card and stores it in the database 112. Make a copy. Alternatively, a personal computer or the like is connected to the USB terminal 108, and audio data or text data corresponding to the message is copied from the personal computer to the database 112.

Moreover, the number of the corresponding situation is also included in these audio data and text data. Then, when the detection condition is satisfied, the control unit 120 sends a message using voice data and text data corresponding to the number of the situation where the detection condition is satisfied.

The method of sending a message using the voice data and text data copied to the database 112 is the same as the sending method described above in the explanation of step S19, so a detailed explanation will be omitted here.

Information acquired from the OBD, information measured by the GPS sensor 109, and information measured by the illuminance sensor 111 are used to determine whether the detection conditions in each situation described above are satisfied. In this regard, the OBD is a system commonly provided in vehicles, the GPS sensor 109 is a sensor commonly provided in car navigation devices for driving guidance, and the illuminance sensor 111 is used for automatic dimming of the touch panel 101, etc. This is a sensor commonly included in car navigation devices for this purpose. In other words, the present embodiment can be realized by utilizing information measured by a car navigation device or a device generally included in a vehicle for this embodiment.

<Operation guidance function>
Next, the operation guidance function performed by the control unit 120 will be explained.
The control unit 120 performs the following processing in order to realize the operation guidance function.

The control unit 120 displays a map around the current location on the touch panel 101 at any time based on map information registered in the database 112, and displays a destination setting button. Furthermore, when the touch panel 101 detects that a position corresponding to the display position of the destination setting button is pressed, the control unit 120 performs a destination setting process. In the destination setting process, a destination setting menu is displayed on the touch panel 101 to prompt the user to select a destination setting method. The destination setting menu includes a telephone number search button and an address search button that prompt the user to select a destination setting method. If it is detected that the telephone number search button has been pressed, a telephone number input screen is displayed, and location information corresponding to the input telephone number is acquired from the database 112. If it is detected that the address search button has been pressed, an address selection input screen is displayed, and location information corresponding to the input address is acquired from the database 112. The acquired location information is then set as destination location information, and a recommended route from the current location to the destination is determined based on the road network information stored in the database 112. As a method for calculating this recommended route, a known method such as Dijkstra's method can be used, for example.

Then, the control unit 120 displays the calculated recommended route together with a surrounding map. For example, the route from the current location to the destination is displayed as a recommended route in a predetermined color (for example, red). These processes are similar to those of a general navigation system.

<Modified example>
Although the embodiments described above are preferred embodiments of the present invention, the scope of the present invention is not limited to only the above embodiments, and various modifications may be made without departing from the gist of the present invention. It is possible to implement For example, it is possible to modify the above embodiments as described below.

First, in the item <Adding a message> above, it was explained that audio data or text data corresponding to a message can be added.

The data to be added may be voice data recorded directly or indirectly by the user. For example, audio data obtained by recording the user's own voice or audio data obtained by recording the voices of the user's family may be converted into a format that can be used by the message sending device 100 and added.

The reason for this will be explained. Since the message sending device 100 works on the psychological state, the effective sound of the message and the content of the effective message differ depending on each user. In other words, the content of messages to effectively encourage self-talk differs from person to person, and it is necessary to find a message that suits each person. Therefore, for example, the user can record the voice of the user's lover or family member (wife, children) directly using a recording device, or indirectly by asking a family member, etc., and send it as a message. It's good to do that. This is good because it is possible to send a message suitable for the user using the message sending device 100.
It is also preferable to add text data created by the user.

Further, the data to be added may be provided by the manufacturer of the message sending device 100 for a fee or free of charge.

For example, the voice of a character voice actor affiliated with the manufacturer may be provided as voice data. In this case, it is preferable to provide voice data in which the character's favorite phrase is added to the message. Further, it is preferable to provide text data in which the character's favorite phrase is added to the message. In this way, a message with a character according to the user's preference is sent out, and the user becomes more interested in the message, so that the user concentrates on listening to or watching the message. Furthermore, since the message sending device 100 works on the user's psychology, it is good because the user can easily accept the contents of the message.

Further, it is preferable that the data to be added be created by each user who has purchased the message sending device 100, instead of creating the data to be added by the manufacturer. In this way, unexpected message data not expected by the manufacturer can be added.

For example, additional data created by each user may be converted into a format that can be used by the message sending device 100 so that it can be exchanged between users over the Internet. In order to facilitate the exchange, for example, the manufacturer may create a site such as a bulletin board that each user can view, and enable the exchange on this site.

In addition, instead of exchanging data one-on-one between users, the manufacturer prepares a site and a server for uploading additional data, and each user accesses the site to create additional data that he or she has created. It is a good idea to make it possible to upload files onto the server. Then, it is preferable to download and use additional data uploaded by other users. In this way, additional data created by a certain user can be used by a plurality of other users. Further, for example, the number of times each additional data has been downloaded may be displayed on the site, or a ranking may be displayed such that additional data with a large number of downloads is ranked higher. By doing this, it is possible to know which additional data is popular.

Furthermore, in order to encourage uploading of additional data, it is preferable to provide some kind of incentive to the uploading user depending on the number of uploads or the number of times the uploaded additional data has been downloaded by other users. For example, a setting may be made in which a predetermined number of points are required for downloading, and the predetermined points may be given to the user who uploads the content. In this case, it would be better to increase the points given according to the number of downloads of the uploaded additional data by other users, as this would provide an incentive to create better additional data that will be downloaded a lot. Alternatively, cash may be used instead of predetermined points. In other words, it is preferable that the manufacturer collects cash from the user who downloads the content and pays the collected cash to the user who uploads the content. Furthermore, using a ranking format as described above is good because it provides an incentive for users who aim for a high ranking.

Furthermore, as another modification, in the above description, when there are multiple messages to be sent for one situation, it has been explained that which message to send is randomly determined. Instead of doing this, a plurality of messages may be selected in order. Further, the message may be selected by the user in advance. Additionally, messages may be selected based on measurements related to detection conditions. For example, taking situation No. 1 as an example, the driver's level of emotional stress is inferred based on the deceleration/acceleration value at the time the foot brake is pressed, and a message is sent based on the inferred level of emotional stress. You may choose. Furthermore, after sending the message, it is preferable to notify the user which situation has occurred based on the detection conditions.

In addition, as another modification, in the above description, a series of messages were sent when the message sending timing came, but the message may be divided and sent, for example, twice. For example, after transmitting to the user a message for switching the user's psychological state to another psychological state, it is preferable to further transmit to the user a message indicating instructions regarding the operation of the mobile object. . For example, when it is time to send a message, a message that calms the user's psychological state, such as "You're surprised! Calm down! Calm down," is first sent. After that, instructions regarding steering wheel operation, accelerator and brake operation are provided. For example, messages such as "Please slow down slowly" or "Please leave a longer distance between vehicles" are sent.

In this way, a message for switching the user's psychological state can be sent first, and instructions regarding the operation can be sent after the user's psychological state has been changed. In this regard, even if an instruction regarding the operation is sent out first without doing this, it is assumed that the user who is in an excited state may not calmly listen to the instruction regarding the operation. However, with this device, a message is first sent to switch the user's psychological state, and then the user's psychological state is first switched. For example, the user is in a calm state before sending instructions. This is good because the user can calmly listen to instructions regarding operations.

In addition, as another variation, when it is detected that a situation corresponding to a violation of traffic rules has occurred due to the detection condition being met, what kind of operation should be performed to prevent the violation from occurring? It is preferable to send an explanation message to the user. In this way, the user can know what kind of operation should be performed to prevent a traffic rule violation from occurring.

In this case, the ``message explaining what action should have been taken to avoid the violation'' could be, for example, a message such as ``I stepped on the accelerator too much'' or ``I should have applied the brakes earlier.'' good. As a result, when a traffic rule violation occurs, the user not only knows that a traffic rule violation has occurred, but also knows how to perform an operation to prevent the violation from occurring. Therefore, the user can avoid making similar operational errors in future operations.

Furthermore, a message may be sent explaining what kind of traffic rule the violated traffic rule is. In this way, the user can know what kind of traffic rule the user has violated. This allows the user to know not only the fact that a traffic rule violation has occurred, but also the content of the traffic rule that was violated. In this regard, there are a wide variety of traffic rules, and it is possible that the user may not fully understand all the traffic rules, but the messages sent by this device allow the user to understand traffic rules that they were not fully aware of. It is good because

Furthermore, it is preferable to send each of the above-mentioned messages in such a way that the messages can be detected even when the user is driving the vehicle. This is good because the user can reliably perceive the message. While operating a moving object, for example, the user visually looks ahead or in the rear view mirror, grips the handle and rotates the handle using the sense of touch, or depresses the accelerator or brake. Therefore, it is conceivable to send a message so that the user can detect it by using abilities other than the user's five senses that are used for such operations. For example, it is preferable to send a voice message so that it can be detected by the auditory senses of a user who is relatively unused to the operation. Additionally, it is also good to display a message on the display device.

Further, as another modification, the message sending device 100 may be realized by a device having a drive recorder function or a device having a radar detector function. Furthermore, the car navigation device that implements the message sending device 100 may also have the functions of a drive recorder, a radar detector, and the like.

Note that the above message sending device can be realized by hardware, software, or a combination thereof. Further, the message sending method performed by the above message sending device can also be realized by hardware, software, or a combination thereof. Here, being realized by software means being realized by a computer reading and executing a program.

Such programs can be stored and provided to a computer using various types of non-transitory computer readable media. Non-transitory computer-readable media includes various types of tangible storage media.

The detection conditions and detection method for this situation are "Circle 1 → Detect the approach of a car in front using the image from the drive recorder", so the control unit 120 analyzes the image input from the drive recorder connection unit 106. , monitor whether the vehicle in front is approaching. Then, "circle 2 → monitor the vehicle speed of the own vehicle from OBD information, and detect that the vehicle is stuck in a traffic jam on the condition that slowing down is detected." Therefore, the control unit 120 controls the vehicle speed input from the OBD connection unit 107. When the vehicle speed falls below a predetermined speed, it is determined that the detection conditions are met and it is detected that the vehicle is stuck in a traffic jam .

The detection conditions and detection method for this situation are as follows: ``Circle 1 → From map information and measured position information, check that the vehicle is stopped at a confluence point such as an intersection.Detect the flow of vehicles ahead using images from the drive recorder. Therefore, the control unit 120 confirms that the vehicle is stopped at a confluence point such as an intersection, based on the map information stored in the database 112 and the position information measured by the GPS sensor 109. Additionally, by analyzing the video input from the drive recorder connection unit 106, the flow of the vehicle ahead is detected. Then, when the vehicle is stopped at a merging point such as an intersection and there is a flow of traffic ahead, it detects that the blinker is blinking from the OBD information, and if it is an AT vehicle, the shift position is changed. Confirm from the OBD information that it is not "P", "R" or "N". It also confirms that the driver is pressing the foot brake, and if the vehicle does not move for several tens of seconds in this state, it detects that the vehicle is waiting to enter the road and cannot enter the road. ” Therefore, based on the information input from the OBD connection unit 107, the control unit 120 determines whether the turn signal is blinking, the shift position is “D”, etc., and the foot brake is depressed. If the vehicle does not move for several tens of seconds, it is determined that the detection conditions are met and it is detected that the vehicle cannot enter the road .

The detection conditions and detection method for this situation are "Circle 1 → Determine whether the road the vehicle is traveling on is an expressway, etc. from the map information, traffic rule database, and measured position information." Therefore, the control unit 120 determines that the vehicle is currently traveling on an expressway based on the map information and traffic rule database stored in the database 112 and the position information measured by the GPS sensor 109. If the determination is successful, a violation will be issued under the condition that the minimum speed is less than the legal speed (50 km for expressways with two or more lanes) based on the vehicle speed obtained at regular intervals from Maru 2 → OBD. Detection.'' Therefore, the control unit 120 monitors the vehicle speed input from the OBD connection unit 107, and when the vehicle speed becomes less than the prescribed legal speed, it determines that the detection condition is met and detects a violation . .

The detection conditions and detection method for this situation are "Circle 1 → Determine the speed limit of the road on which the vehicle is traveling from the map information, the traffic rule database, and the measured position information." Therefore, the control unit 120 uses the database 112 The speed limit of the road on which the vehicle is currently traveling is determined based on the map information and traffic rule database stored in the system and the position information measured by the GPS sensor 109. Then, since "circle 2 → monitor the vehicle speed obtained from the OBD at regular intervals, and detect a violation on the condition that the speed limit has been exceeded", the control unit 120 controls the vehicle speed input from the OBD connection unit 107. If the vehicle speed exceeds the speed limit, it is determined that the detection conditions are met and a violation is detected.
