DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, modes for carrying out the present invention (hereinafter referred to as embodiments) will be described in detail with reference to the accompanying drawings. In the following figures, the same numbers or symbols are given to the same elements throughout the description of the embodiments.

[Basic concept/basic configuration]
FIG. 1 is a diagram for explaining an overview of a virtual passenger system 1 according to an embodiment of the present invention. The virtual passenger system 1 is a system in which a virtual passenger who is not actually riding with the driver praises the driver when an incident does not occur at a pre-recorded incident location.

The virtual passenger system 1 includes a virtual passenger device 10 , a drive recorder 30 mounted on a vehicle 20 , and a terminal 40 within the vehicle 20 . The virtual passenger device 10 is connected to each of the drive recorder 30 and the terminal 40 via a wireless communication network. The virtual passenger device 10 may be an on-premises or cloud server, but in this embodiment, it is a cloud server. Further, although the vehicle 20 is a car in this embodiment, it may be any vehicle that requires a driver 50, and may be a bicycle or a motorcycle. Further, in this embodiment, the terminal 40 is a mobile terminal held by the driver 50, but it may also be a car navigation terminal installed in the vehicle.

The terminal 40 sets the virtual passenger 60 based on the driver's 50 operation input. The virtual passenger 60 can be set as the driver's family, friends, boss, real people such as entertainers or celebrities, or characters. Specifically, the virtual fellow passenger 60 can be set by starting an application installed on the terminal 40 and storing the audio data stored on the terminal 40 in the virtual fellow passenger device 10. Note that it is also possible to select and set a virtual fellow passenger from among the virtual fellow passengers stored in the virtual fellow passenger device 10, or to set a plurality of people as the virtual fellow passenger 60.

The drive recorder 30 acquires the driving situation of the vehicle 20 and transmits the driving situation to the virtual passenger device 10 at a predetermined timing. The driving situation includes at least position information acquired by a positioning sensor (e.g., GNSS sensor or GPS sensor), and moving and still images inside and outside the vehicle taken by an on-vehicle camera. It may also include various situations related to the vehicle acquired from on-vehicle sensors.

The virtual passenger device 10 determines whether an incident has occurred in the vehicle 20 based on the driving situation received from the drive recorder 30 and pre-stored incident occurrence information. Here, the incident occurrence information includes incidents that have occurred in the past, the location of the incident, etc., and is information obtained from the vehicle 20 or terminal 40 via a communication network, a website, SNS, etc. This information is created from the information obtained.

When the virtual passenger device 10 determines that no incident has occurred in the vehicle 20, it sends a voice message to the terminal 40 praising the fact that the incident did not occur, that is, the driver 50 drove safely to avoid the incident. Send to. Then, the terminal 40 that has received the voice message causes the virtual fellow passenger 60 to speak the message.

According to such a virtual passenger system, a driver who has driven safely to avoid an incident at an incident location can be praised by the virtual passenger's speech rather than text information or mechanical voice. This allows the driver to virtually feel the feeling of being evaluated by fellow passengers, thereby increasing the driver's awareness of safe driving. Furthermore, by making the driver feel the presence of a passenger through the speech of the virtual passenger, it is possible to improve the driver's awareness of safe driving.

[Functional configuration of virtual passenger system]
FIG. 2 is a diagram showing the functional configuration of the virtual passenger system 1 according to the embodiment of the present invention. The virtual passenger system 1 includes a virtual passenger device 10, a drive recorder 30, and a terminal 40 connected to the virtual passenger device 10 via a wireless communication network.

(Functional configuration of drive recorder)
The drive recorder 30 has the function of a driving status acquisition unit that acquires the driving status of the driver 50 who drives the vehicle 20. The drive recorder 30 includes a transmitting/receiving section 31 that transmits and receives data to and from the virtual passenger device 10, a control section 32, a storage section 33, various sensors 34, and a camera 35. Examples of the various sensors 34 include a GPS (Global Positioning System) sensor, a sound detection sensor, a vehicle speed sensor, an acceleration sensor, a gyro sensor, a temperature sensor, a pressure sensor, an infrared sensor, and an optical sensor.

The control unit 32 acquires moving images and still images inside and outside the vehicle (hereinafter simply referred to as images when not distinguishing between inside and outside the vehicle, moving/still images) from the camera 35, and determines the date and time when the image was taken and the correspondence. It is attached and stored in the storage unit 33. The control unit 32 also acquires vehicle conditions such as position information (latitude, longitude), voice, speed, acceleration, steering wheel rotation angle, amount of brake depression, and internal/external temperature from various sensors 34, and determines the vehicle conditions. It is stored in the storage unit 33 in association with the detected date and time.

The storage unit 33 stores vehicle information regarding the vehicle, such as the driver ID, vehicle type, and vehicle ID, in addition to images and vehicle conditions. The vehicle information may hold driver characteristics (age, driver history, industry, etc.) in association with the driver ID. Further, the vehicle information may hold characteristics of the vehicle (vehicle class, vehicle maintenance information, mileage, etc.) in association with the vehicle ID. The transmitting/receiving unit 31 transmits the image and vehicle status stored in the storage unit 33 and the vehicle information stored in the storage unit 33 to the virtual passenger device 10 successively or at a predetermined timing as the driving status.

(Functional configuration of virtual passenger device)
The virtual passenger device 10 includes a transmitting/receiving unit 11 that transmits and receives data to and from the drive recorder 30 and the terminal 40, a management unit 12, a selection unit 13, a determination unit 14, a message generation unit 15, a storage unit 16, Equipped with

The storage unit 16 includes a virtual passenger database (herein, the database may be referred to as DB) 160 that stores the voice data of the virtual passenger 60 set on the terminal 40, and a virtual passenger database 160 that stores voice data of the virtual passenger 60 set on the terminal 40, and a virtual passenger database (herein, the database may be referred to as DB). The vehicle includes an incident database 161 that stores incident information regarding the incident, and a message database 162 that stores messages uttered by a virtual passenger when an incident does not occur. In this embodiment, since the virtual passenger device 10 is a cloud server, the storage unit 16 is preferably configured with cloud storage or a distributed ledger.

The management unit 12 generates and updates a virtual fellow passenger DB 160 based on the virtual fellow passenger information acquired from the terminal 40 via the transmitting/receiving unit 11, and records and manages the virtual fellow passenger DB 160 in the storage unit 16.

FIG. 3 is a diagram schematically showing a virtual fellow passenger DB according to this embodiment. The virtual passenger information in the virtual passenger DB includes a virtual passenger ID that identifies the virtual passenger, a driver ID that identifies the driver who set the virtual passenger, a virtual passenger name, voice data of the virtual passenger, etc. Contains information indicating.

Furthermore, the management unit 12 creates incident information based on the driving situation acquired from the drive recorder 30 of the vehicle 20 in which the incident occurred via the transmitting/receiving unit 11. Then, the management unit 12 generates and updates the incident DB 161 based on the created incident information, and records and manages the incident DB 161 in the storage unit 16. Note that the incident information is not limited to the vehicle in which the virtual passenger system 1 is installed, and may include information acquired from drive recorders of other vehicles. Furthermore, the management unit 12 may create incident information from information related to incidents posted on websites, SNS, etc., in addition to the driving status.

In the present embodiment, an incident includes both a near-miss situation that may cause a danger such as an accident, and an accident. In detail, the incident includes driving advice indicating a crime related to a vehicle, an accident related to a vehicle, a situation that can lead to a crime or an accident related to a vehicle, or a situation that can cause a crime related to a vehicle. Driving advice includes, for example, checking for pedestrians, school zones, lots of parking on the road, be careful of running out, narrow roads, not being able to separate, height restrictions, safe driving items, etc.

FIG. 4 is a diagram schematically showing an incident DB according to an embodiment of the present invention. The incident information includes information indicating an incident ID for identifying the incident, the latitude/longitude of the place where the incident occurred, the category of the incident, the name of the incident, the start time of the incident, the end time of the incident, and the like. Furthermore, the incident information includes the characteristics of the driver who caused the incident (age, driver history, industry, etc.), vehicle characteristics (vehicle class, vehicle type, vehicle maintenance information, vehicle inspection information, mileage, etc.). May contain information. Note that the incident information only needs to include at least the incident name and the latitude/longitude of the place where the incident occurred.

Returning to FIG. 2, the selection unit 13 selects an incident from the incident DB 161 based on the position information of the driving situation acquired from the drive recorder 30 of the vehicle 20. Specifically, the selection unit 13 acquires incident information having location information that matches the acquired location information from the incident DB 161.

The selection unit 13 may acquire, from the incident DB 161, incident information having position information within a predetermined range including the acquired position information, even if the incident information does not match the acquired position information. As a result, the area for determining whether an incident has occurred can be expanded to include not only the location where the incident occurred but also the vicinity of the location where the incident occurred. Note that the predetermined range may be set in advance and may be set for each incident.

Further, the selection unit 13 may include the current time together with the location information in the selection conditions, and can select only incidents that occur only at the current time, for example, incidents that occur at night.

Further, the selection unit 13 may include characteristics of the vehicle and characteristics of the driver in addition to the location information in the selection conditions, and can limit and select incidents that match the vehicle and driver. For example, if the vehicle is a truck, you can select an incident that occurs on a truck, and if the driver is a novice, you can select an incident that occurs among beginners. Furthermore, each condition may be weighted and determined. In this way, by making judgments that take into account multiple factors such as time information, vehicle characteristics, and driver characteristics, it is possible to select incidents that truly required attention for the driver or vehicle. become.

The determining unit 14 determines whether the incident selected by the selecting unit 13 has occurred, based on the driving situation acquired from the drive recorder 30 of the vehicle 20. Specifically, the storage unit 16 includes a judgment condition DB (not shown) that stores judgment conditions for each incident, and the judgment unit 14 acquires the judgment condition for the incident selected by the selection unit from the judgment condition DB. Then, the determination unit 14 determines whether an incident has occurred, depending on whether the driving situation satisfies the determination conditions. The determining unit 14 also determines whether an incident has occurred based on learning data created from the driving situation in which the incident occurred.

When the selection unit 13 acquires incident information having position information within a predetermined range including the acquired position information from the incident DB 161, the determination unit 14 selects the incident information until the selection unit 13 no longer acquires the same incident information. It is determined whether or not the incident selected by the selection unit 13 has occurred based on all of the driving conditions. That is, the presence or absence of an incident is determined not only at the location where the incident occurred but also in a range extended to the vicinity of the location where the incident occurred.

The message generation unit 15 generates an audio message in which the virtual passenger 60 set on the terminal 40 praises the driver 50 in response to the determination unit 14 determining that no incident has occurred. Note that if the determination unit 14 determines that a plurality of incidents have not occurred, the incident for which a message is to be generated may be selected according to a preset priority or the like. Specifically, first, the message generation unit 15 acquires, from the message DB 162, a message of an incident for which the determination unit 14 has determined that no incident has occurred.

Here, the message stored in the message DB 162 is text information praising the driver 50, and is preferably set for each incident or each category of incident, and the message also includes the incident name. It is desirable that For example, if you avoid an incident in a school zone, the message will be ``You successfully passed the school zone! You did it!'', and if you avoid a rear-end collision, the message will be ``You didn't cause a rear-end accident.As expected. ” etc. are set.

Next, the message generation unit 15 acquires the voice data of the virtual fellow passenger 60 set in the terminal 40 from the virtual fellow passenger DB 160. Subsequently, the message generation unit 15 generates a voice message for the virtual fellow passenger 60 from the acquired message based on the acquired voice data. Thereby, it is possible to create audio data that reflects the characteristics of the person or character who is the virtual passenger 60, such as the tone of voice, phrasing, and tone of voice. The message generating section 15 then transmits the generated voice message to the terminal 40 via the transmitting/receiving section 11.

(Functional configuration of terminal)
The terminal 40 is operated by the driver 50 and is, for example, a mobile terminal, a car navigation terminal, etc., and is connected to the virtual passenger device 10 via a network so that information can be transmitted and received. The terminal 40 includes a display input/output unit (not shown) configured with, for example, a touch panel, and a sound output unit (not shown) configured with, for example, a speaker.

When the driver 50 gets into the vehicle, the driver 50 operates the display input/output unit to start a predetermined application and sets the virtual passenger 60 using the application. Thereafter, when the driver 50 starts the vehicle 20, the drive recorder 30 starts transmitting the driving status to the virtual passenger device 10. When an incident is avoided during driving, a voice message received from the virtual passenger device 10 in which the virtual passenger 60 praises the driver 50 is output from the sound output unit.

The functional configuration of the present system described above is just an example, and one functional block (database and functional processing unit) may be divided, or multiple functional blocks may be combined into one functional block. Each functional processing unit is stored in a storage device (storage unit) such as a ROM (Read Only Memory), flash memory, SSD (Solid State Drive), or hard disk by a CPU (Central Processing Unit) built into the device or terminal. This is realized by reading out a computer program (for example, core software or an application that causes the CPU to execute the various processes described above), and executing the computer program by the CPU. In other words, each functional processing unit reads and writes necessary data such as tables from a database (DB) stored in a storage device or a storage area in memory, and in some cases, This is realized by controlling hardware (for example, input/output devices, display devices, communication interface devices). Further, the database (DB) in the embodiment of the present invention may be a commercial database, but it also means a simple collection of tables and files, and the internal structure of the database itself does not matter.

[Processing flow]
FIG. 5 is a diagram showing a virtual passenger processing flow executed by the virtual passenger system according to the embodiment of the present invention. In this embodiment, the virtual fellow passenger process is executed by the virtual fellow passenger device.

First, the management unit 12 generates and updates the virtual passenger DB 160 (see FIG. 3) based on the virtual passenger information acquired from the terminal 40 via the transmitting/receiving unit 11, and stores and manages the virtual passenger DB 160 in the storage unit 16 ( S1). Next, the selection unit 13 acquires the driving situation from the drive recorder 30 (S2). Next, the selection unit 13 selects incidents whose location information matches or falls within a predetermined range from the incident DB 161 (see FIG. 4) based on the location information included in the driving situation acquired in S2 (S3).

Next, the determination unit 14 determines whether the incident selected in S3 has occurred, based on the driving situation acquired in S2 (S4). If an incident has occurred (YES), the process proceeds to S7, and if no incident has occurred (NO), the process proceeds to S5.

Next, in response to the determination that no incident has occurred in S4, the message generation unit 15 generates a voice message in which the virtual passenger 60 set on the terminal 40 praises the driver 50 (S5). . Next, the transmitting/receiving unit 11 transmits the voice message generated in S5 to the terminal 40, and outputs it from the sound output unit of the terminal 40, thereby causing the virtual fellow passenger 60 to speak (S6).

Next, the selection unit 13 determines whether the driving situation has been acquired from the drive recorder 30. If the driving status is not acquired (NO), it is determined that the vehicle 20 has stopped and driving has ended, and the process is terminated; if the driving status is acquired (YES), it is determined that driving is continuing. Then, the process returns to S3 (S7).

According to such a virtual passenger system, it is possible to praise a driver who has driven safely to avoid an incident at or near the incident location using the virtual passenger's speech rather than text information or mechanical voice. can. This allows the driver to virtually feel the feeling of being evaluated by fellow passengers, thereby increasing the driver's awareness of safe driving. Furthermore, by making the driver feel the presence of a passenger through the speech of the virtual passenger, it is possible to improve the driver's awareness of safe driving.

A virtual passenger can be set by the driver, and can be chosen from a close family member, a favorite celebrity or character, a boss with whom you feel comfortable, etc., allowing you to select a virtual passenger according to your mood at the time. I can do it.

[Modified example]
(1) For example, the virtual passenger system can exclude incidents that do not occur or rarely occur depending on the driving environment of the vehicle by including environmental information such as the weather at the time of the incident in the incident information. I can do it. This enables more accurate driving evaluation.

(2) For example, the virtual passenger system can select incidents according to the individual's driving history by using the driver's accident history and/or incident history as selection conditions in the selection unit. In addition, the message generation unit generates a message according to the driver's accident history and/or incident history, according to the individual's driving history, if the determination unit determines that multiple incidents have not occurred. You may also select incidents to report.

As a result, it is possible to praise the driver only for incidents that are highly necessary for the driver, such as incidents related to past accidents or incidents that occur frequently. As a result, frequent praise from the virtual passenger can prevent the driver from finding the virtual passenger a nuisance and reducing the effectiveness of raising awareness of safe driving.

(3) For example, the virtual passenger system may include the driver name in the virtual passenger information. Thereby, the message generation unit can create a message including the driver's name, for example, ``You didn't cause the rear-end accident. As expected of you, Taro.'' This makes it easier for drivers to feel that they are being praised, which improves the effectiveness of raising awareness of safe driving. It also increases the feeling of having a passenger.

(4) For example, the virtual passenger system stores map information in the storage unit, and based on the map information and incident information, the incident map (see Fig. 6 ) may be generated and sent to the driver's terminal, etc. This allows drivers to check the location where the incident is occurring and alert them to safe driving. The incident map may display a different icon for each incident, or may be searchable by incident date or incident name. Additionally, comments collected from the driver of the vehicle where the incident occurred may also be displayed.

(5) For example, the virtual passenger system accumulates incidents determined by the determination unit to be incidents regarding the driver's driving over a predetermined period of time (one day, one week, etc.), and collects the incidents that are the most frequent or the most dangerous. You may also extract incidents that occurred. If the extracted incident does not occur during subsequent driving, praise may be given for improved driving. Additionally, the extracted incidents may be fed back to the driver. Thereby, it is possible to further improve the driver's awareness of safe driving.

(6) For example, the virtual passenger system may include the incident name and incident classification in the virtual passenger information. The message generation unit can select a virtual passenger based on the incident determined by the determination unit to have not occurred, and generate an audio message in which the selected virtual passenger praises the driver. Thereby, the voice message of the virtual passenger can be different for each incident and for each category of incident. As a result, voice messages can be tailored to the level of danger and importance of the incident, such as a voice message from a superior for high-risk incidents, and a voice message from a character for minor incidents such as warnings to be careful.

(7) For example, the virtual passenger system may include a point granting unit that grants points when the determining unit determines that an incident has not occurred. By accumulating points and receiving gifts, you can increase your motivation to drive safely.

Although the present invention has been described above using the embodiments, it goes without saying that the technical scope of the present invention is not limited to the scope described in the above embodiments. It will be apparent to those skilled in the art that various changes or improvements can be made to the embodiments described above. Furthermore, it is clear from the claims that forms with such changes or improvements may also be included within the technical scope of the present invention. In the above embodiments, the virtual passenger system has been described with the present invention as a physical invention. However, in the present invention, the method executed by the virtual passenger system and the program that causes the virtual passenger system to function as various means are explained. It can also be considered an invention.
