Description of the Related Art Conventionally, a toll road automatic toll collection system (ETC (registered trademark): Electronic Toll Collection System) is known as a usage form of short-range wireless communication such as DSRC (Dedicated Short Range Communication). ETC provides a service (ETC service) that automatically collects tolls by performing short-range wireless communication between ETC roadside devices installed at toll gates on toll roads and on-board devices mounted on vehicles To do. A user (for example, a driver) attaches (inserts) an ETC IC card to the vehicle-mounted device and uses the ETC service.

  In recent years, other services using the above-described vehicle-mounted device are also being studied. For example, a credit settlement service (EMV service) using a credit card (EMV card) capable of performing payment in conformity with the EMV standard, a service enabling payment using an IC card having an electronic money function, etc. Is mentioned. The EMV standard is a unified standard for IC credit card settlement agreed between Europay in Europe, MasterCard in the United States, and Visa.

  Since this type of service can be used with an IC card mounted on the vehicle-mounted device, an appropriate IC card is mounted on the vehicle at an appropriate timing before the vehicle arrives at a point where various services are provided. It is desirable to be attached to the vessel.

  Therefore, the user is notified of the type of service that exists on the guidance route searched by the navigation device, and it is determined whether or not the content of the provided service corresponds to the IC card mounted on the vehicle-mounted device. There has been proposed a technique for providing guidance when not corresponding (see Patent Document 1).

Note that ECU is an abbreviation for Electronic Control Unit, and is configured as a so-called computer system including a CPU, a ROM, a RAM, and the like.

  The vehicle speed sensor 11 is attached to a wheel, for example, and generates a pulse signal corresponding to the rotation thereof. The vehicle speed sensor 11 is used to detect the traveling speed (vehicle speed) of the vehicle from the time interval of the pulse signal. . The pulse signal is output to the vehicle-mounted device 10 (control unit 15).

  The engine ECU 12 performs engine control for automatically starting or stopping the engine when a user operates a switch (not shown). The engine ECU 12 detects the start of the engine and the stop of the engine due to the operation of the switch, and outputs the detection result to the control unit 15. Further, the engine ECU 12 detects ACC on and ACC off, and outputs the detection result to the control unit 15 as an ACC on / off signal (ACC signal). The ACC signal may be input from other than the engine ECU 12.

  The navigation device 13 includes a navigation ECU (hereinafter referred to as a navigation ECU) 33 that executes processing for realizing a navigation function, a GPS receiver 331, a gyroscope 332, and a map database (map DB) 333.

  The navigation ECU 33 calculates the current position (absolute position represented by latitude and longitude) and the traveling direction (absolute direction) of the vehicle based on detection information from the GPS receiver 331 and the gyroscope 332. In addition, the navigation ECU 33 reads map data from the map database 333, and specifies the current position and traveling direction of the vehicle in the map represented by the map data, a traveling route based on the route searched by the user, and the like.

The vehicle-mounted device 10 includes a wireless communication unit 14, a control unit 15, an HMI (Human Machine Interface) unit 16, a card processing unit 17, and a storage unit 18.
The wireless communication unit 14 performs data communication (short-range wireless communication) with the roadside device 2 using a 5.8 GHz band radio wave applied to DSRC. Data received from the roadside device 2 Is transmitted to the control unit 15 and the data input from the control unit 15 is transmitted to the roadside machine 2.

The roadside machine 2 is installed in the vicinity of the traveling road of the vehicle, and various types are provided depending on the application, such as the ETC roadside machine 21, the ETC warning antenna 22, and the EMV roadside machine 23, for example.
The ETC roadside machine 21 is a roadside machine 2 installed at an ETC entrance gate and an exit gate of a toll gate on a toll road and used for an ETC service.

  The ETC notice antenna 22 is installed before the ETC gate or after leaving the toll road service area, and detects the state of the ETC card mounted on the in-vehicle device 10 by communicating with the in-vehicle device 10. And the roadside machine 2 which transmits the data containing the message according to the detected mounting state to the onboard equipment 10 is said.

  The EMV roadside machine 23 is a roadside machine 2 that is installed in a store such as a gas station or a restaurant and provides a settlement service for an IC card other than an ETC card (here, an EMV card).

  The HMI unit 16 includes an input unit 61, a speaker 62, and a display unit 63. The input unit 61 receives an input operation (such as whether or not an EMV card can be settled) from a user (for example, a driver), and outputs the received operation content to the control unit 15. The speaker 62 notifies the user by sound or voice according to an instruction from the control unit 15. The display unit 63 is configured by a liquid crystal display device or the like, and notifies the user by an image according to an instruction from the control unit 15.

  The card processing unit 17 includes a card connector (not shown) to which the IC card 3 can be attached and detached. That the IC card 3 is detachable means that the IC card 3 can be attached to and detached from the card processing unit 17 (card connector). The mounting of the IC card 3 means that the IC card 3 is held in the card processing unit 17 (card connector). In an appropriate holding state, the stored information of the IC card 3 is stored in the card connector. Through which data can be read and written. Further, the appropriate holding state refers to a state where the IC card 3 is held correctly and in the correct direction with respect to the card processing unit 17. The card processing unit 17 determines whether the IC card 3 is attached (whether the IC card 3 is held, whether the holding state is appropriate, whether the held IC card 3 itself is appropriate, And the detection result is output to the control unit 15. In addition, as a holding mode of the IC card 3 by the card processing unit 17 (card connector), a mode in which the IC card 3 is held is common, but is not particularly limited, and other holding modes are possible. It may be.

  Although there are various types of IC cards, in this embodiment, ETC cards and EMV cards (including payment cards other than ETC) are collectively referred to as IC cards 3. In the IC card 3, storage information such as an ID (Identification) (hereinafter referred to as a card ID) set for each IC card 3 and an expiration date is written in advance. The card processing unit 17 can read the stored information written in the IC card 3 in a state where the IC card 3 is mounted in an appropriate holding state, and can transmit data transmitted from the control unit 15 to the IC card. 3 can be written.

  Further, the card processing unit 17 detects each piece of information as follows in accordance with a card detection instruction from the control unit 15. That is, the card processing unit 17 first detects whether or not the IC card 3 is attached (card attachment / detachment information). When the IC card 3 is mounted, it is detected whether or not the IC card 3 is in an appropriate holding state (card holding state information). When in an appropriate holding state, the storage information (card storage information) is read from the IC card 3. The card storage information includes a card expiration date, a card ID, and a card type detected by reading the card ID. The card type refers to the type of ETC card or EMV card.

  Further, the card processing unit 17 detects whether or not the card expiration date has expired in the read card storage information (card expiration date information). Whether or not it has expired is determined based on the current date and time acquired using the navigation device 13 (or the time measuring device having a time measuring function) or the time information acquired from the roadside device 2.

  Further, the card processing unit 17 detects the number of reading interruptions. Since it takes several seconds to read the IC card 3 in an appropriate holding state, the reading is interrupted when an operation of attaching the IC card 3 to the card processing unit 17 and removing it immediately is performed. In other words, the reading interruption means that the IC card 3 has been removed from the time when reading of the stored information (card ID, expiration date, etc.) of the IC card 3 is started until the reading is completed (while reading). Say. The number of reading interruptions is the number of reading interruptions that occur between the successful reading of the IC card 3 (that is, after the IC card 3 is normally read) and the next successful reading of the IC card 3. The number of times.

  The card processing unit 17 outputs the card attachment / detachment information, card holding state information, card storage information, card expiration information, and reading interruption count as attachment / detachment operation information (see FIG. 3). The output attachment / detachment operation information is input to the control unit 15.

The storage unit 18 includes, for example, a rewritable flash ROM, and stores a program executed by the control unit 15 and operation history information described later.
Like the ECU, the control unit 15 is configured as a microcomputer centered on a CPU 51, a ROM 52, a RAM 53, and the like, and executes various processes according to programs stored in the storage unit 18. The vehicle-mounted device 10 according to the present embodiment is characterized by a notification control process that performs notification according to an attachment / detachment operation of the IC card 3 with respect to the card authentication unit (card connector) 17. Below, the alerting | reporting control process which the control part 15 performs is demonstrated.

[2. processing]
The notification control process executed by the control unit 15 is repeatedly executed while the execution of the process is enabled by a switch or the like.

[2.1 Notification control processing]
As shown in FIG. 2, when the notification control process is started in the control unit 15, first, in S <b> 105 (S represents a step), it is determined whether engine start is detected according to the detection result by the engine ECU 12. judge. Here, when engine start is not detected, the process waits until engine start is detected. On the other hand, when engine start is detected, the process proceeds to S110. The engine start and stop may be determined according to the on / off state of the ACC signal.

  In S110, a history writing process is performed. In the history writing process, every time a predetermined event (hereinafter referred to as an event) occurs, event acquisition information of a predetermined item for the event is acquired. The event acquisition information includes, for example, the date and time (date and time information) when the event occurred, the place (location information), the vehicle speed when the event occurred, and the like. The event and event acquisition information are referred to as event information. Further, in the history writing process, the IC card 3 attachment / detachment operation information is also acquired. Then, the acquired event information and attach / detach operation information are accumulated as operation history information (see FIG. 3).

  In the history writing process of this step (S110), the event is the engine start, and the date and time (date information) when the engine was started is acquired as event acquisition information. Further, in this step, a card detection instruction is output to the card processing unit 17 to acquire the attach / detach operation information of the IC card 3 at this time. Then, event information including event and event acquisition information and attachment / detachment operation information are stored in the storage unit 18 as operation history information.

In subsequent S115, the operation history information accumulated in the storage unit 18 is statistically analyzed, and a notification setting process (details will be described later) for setting a notification mode according to the analysis result is executed.
Next, in S120, notification processing (details will be described later) for performing notification in the notification mode set in S115 is executed.

  In the subsequent S125, it is determined whether or not an attaching / detaching operation (mounting or extracting operation) has been performed using the detection result of the mounting state of the IC card 3 input from the card processing unit 17. If no operation is detected, the process proceeds to S140. On the other hand, if any operation of attachment or removal is detected, the process proceeds to S130.

  In S130, an IC card process is executed. In the IC card processing, a card detection instruction is output to the card processing unit 17 and the detachment operation information is acquired from the card processing unit 17. And the message according to the acquired attachment / detachment operation information is alert | reported to a user by an audio | voice or an image display using the HMI part 16 (speaker 62 or the display part 63).

  For example, when it is detected that the holding state of the IC card 3 is appropriate as the attachment / detachment operation information, a message “The card can be used normally” is notified. On the other hand, when it is detected that the holding state of the IC card 3 is not appropriate as the attachment / detachment operation information, a message “The card is not inserted normally” is notified. In addition, when an expiration date is detected, a message “expired” is notified. In addition to the example illustrated here, notification by various messages corresponding to the attachment / detachment operation information may be performed.

  In subsequent S135, a history writing process is performed. In the history writing process in this step, the event is an operation of attaching / detaching the IC card 3 in the card processing unit 17. The event acquisition information is the date and time when the attachment / detachment operation was detected and the vehicle speed when the attachment / detachment operation was detected. And these event acquisition information is acquired (a vehicle speed is calculated using the pulse signal output from the vehicle speed sensor 11), the event information consisting of an event and event acquisition information, and the attachment / detachment operation information acquired in S130. And stored in the storage unit 18 as operation history information.

  Next, in S140, it is determined whether or not the vehicle has entered the communication area of the ETC notification antenna 22. Whether the vehicle has entered the communication area is determined based on whether the radio communication unit 14 has received a radio wave from the ETC notification antenna 22. If it is determined that the communication area of the ETC notification antenna 22 has not been entered, the process proceeds to S155. On the other hand, if it is determined that the communication area of the ETC notification antenna 22 has entered, the process proceeds to S145.

  In subsequent S145, a notice antenna passing process is executed. In the notice antenna passing process, first, a card detection instruction is output to the card processing unit 17, and attachment / detachment operation information is acquired from the card processing unit 17. And the information which should be transmitted to the ETC warning antenna 22 among the acquired attachment / detachment operation information is transmitted to the ETC warning antenna 22 using the wireless communication unit 14. Then, when an instruction corresponding to the transmitted information is received from the ETC notification antenna 22, processing according to the instruction is executed.

  For example, when information indicating that the ETC card is not properly installed is transmitted, an instruction to guide the vehicle occupant that the ETC cannot be used is transmitted from the ETC notification antenna 22 as is well known. In this case, in accordance with the received instruction, the vehicle occupant is notified that the ETC cannot be used. For example, the HMI unit 16 is used to notify by voice that “ETC is not available. The example given here is an example of a response with the ETC notification antenna 22, and various instructions are given from the ETC notification antenna 22 according to the transmitted information.

  Next, in S150, a history writing process is executed. In the history writing process of this step, the event is the entry of the ETC advance antenna 22 into the communication area, and the event acquisition information is the entry date and time (date and time when communication with the ETC advance antenna 22 is established), ETC, Information about the installation location of the notification antenna 22 (location information) and instruction content from the ETC notification antenna 22 (notification antenna instruction information) are acquired. And the acquired event information and attachment / detachment operation information are memorize | stored in the memory | storage part 18 as operation history information (refer FIG. 3).

  The information on the installation location includes, for example, information such as the toll road name, the installation location name, and where the installation location corresponds to before the entrance gate, before the exit gate, after leaving the service area, etc. . Alternatively, it includes ID information uniquely assigned to enable identification of these pieces of information.

  In subsequent S155, whether or not the service has been used, specifically, whether or not the installation position of the ETC roadside machine 21 or EMV roadside machine 23 has passed (in the communication area of the ETC roadside machine 21 or EMV roadside machine 23). It is determined whether or not a vehicle has entered. Here, a service using an ETC card is referred to as an ETC service, a service using an EMV card is referred to as an EMV service, and these are collectively referred to as a service. If it is determined that the service is not used, the process proceeds to S170. On the other hand, when it is determined that the service is used (when it is determined that the ETC service or the EMV service is used), the process proceeds to S160.

  As is well known, when a vehicle enters the communication area of the ETC roadside machine 21 and the EMV roadside machine 23, information on the roadside machine is transmitted from the ETC roadside machine 21 and the EMV roadside machine 23. The information transmitted from the ETC roadside machine 21 includes, for example, the name of the installed highway, the name of the installation location, whether it is an entrance gate or an exit date, and the like. In the case of an exit gate, billing information is included. Similarly, the information transmitted from the EMV roadside device 23 includes, for example, a store name, an installation location name, billing information, and the like. In this step, it is determined from the information received by establishing communication with the ETC roadside machine 21 or the EMV roadside machine 23 whether the vehicle has entered into the communication area of the ETC roadside machine 21 or the EMV roadside machine 23. .

  Next, in S160, a service use process is executed. In the service use process, when a vehicle enters the communication area of the ETC roadside device 21 on the entrance gate side in S155, the IC card 3 (ETC card) of information received from the ETC roadside device 21 via the card processing unit 17 Write to. Further, when the vehicle enters the communication area of the ETC roadside machine 21 on the exit gate side in S155, the IC card 3 (ETC card) of the information received from the ETC roadside machine 21 including the billing information by performing a well-known settlement process. Write to. In addition, when a vehicle enters the communication area of the EMV roadside device 23 in S155, a known settlement process is performed, and information received from the EMV roadside device 23 including billing information is written to the IC card 3 (EMV card). Do.

  Next, in S165, a history writing process is executed. In the history writing process of this step, the event is used as a service, and the date and time (date and time information) when the vehicle entered the communication area of the ETC roadside machine 21 or EMV roadside machine 23 as the event acquisition information, the ETC roadside machine 21 or EMV Information about the installation location received from the roadside machine 23 (location information) and the vehicle speed when passing through the ETC roadside machine 21 or the EMV roadside machine 23 are acquired. Then, the acquired event information is stored in the storage unit 18 as operation history information. In the case of the ETC roadside machine 21 and the EMV roadside machine 23 on the exit gate side, the date and time when the settlement process was performed may be acquired as the date and time information.

In subsequent S170, by performing the notification setting process, the operation history information accumulated in the storage unit 18 is statistically analyzed, and a notification mode corresponding to the analysis result is set.
Next, in S175, by performing a notification process, notification according to the notification mode set in S170 is performed.

  In continuing S180, it is determined whether the engine stop was detected. Here, when the stop of the engine is not detected, that is, when the operation of the vehicle is continued, the process proceeds to S125, and a series of processes of S125 to S180 is repeated. On the other hand, if it is determined in S180 that the engine is stopped, the process proceeds to S185.

  Next, in S185, a history writing process is executed. In the history writing process of this step, the event is the engine stop, and the event acquisition information is acquired as the date and time when the engine stop was detected. Further, in this step, a card detection instruction is output to the card processing unit 17 to acquire the attach / detach operation information of the IC card 3 at this time. Then, the acquired event information and attachment / detachment operation information are stored in the storage unit 18 as operation history information.

  In subsequent S190, notification setting processing is executed. In S195, a notification process is executed, and the process proceeds to S105. That is, at the time of getting off, the process of S185-S195 is executed, and then it waits until the engine is started again.

  As described above, the control unit 15 provides information (card error record) indicating that the use of the service is denied due to the mounting state of the IC card 3 by the history writing process in the notification control process shown in FIG. Stored as operation history information. The case where the use of the service is denied due to the mounting state of the IC card 3 is, for example, the case where the IC card 3 required by the service is not normally mounted on the card processing unit 17 when necessary. Also, for example, when the available balance is insufficient or the expiration date has expired.

  Further, the control unit 15 has information that indicates that the attachment / detachment operation has not been performed at an appropriate time (card attachment / detachment timing), or the IC card 3 is erroneously attached to the control unit 15 by the history writing process. Information indicating this (inside out, wrong direction, etc.) is stored as operation history information.

And the control part 15 sets the alerting | reporting aspect according to operation history information by alerting | reporting setting process, and alert | reports by the alerting | reporting aspect set to the user by alerting | reporting process.
[2.2 Notification setting process]
Next, the notification setting process executed in S115, S170, and S190 of the above-described notification control process (FIG. 2) will be described using the flowchart shown in FIG.

  In S205, the service to be used next is predicted. Here, the service usage history (event information included in the operation history information) accumulated in S165 is statistically analyzed to predict the next service usage mode. Specifically, the tendency of the service usage pattern is analyzed by time, day of the week, day, week, and month. Based on this tendency, it is predicted whether the next service to be used is an ETC service or an EMV service.

  For example, if a repetitive pattern of ETC service (entrance) → ETC service (exit) → EMV service (restaurant drive-through) is detected from the analysis result of the operation history information, the ETC service (entrance) ) And ETC service (exit) in that order, the next service to be used is predicted to be an EMV service.

  In addition, if, for example, a tendency to use the ETC service during the morning and evening hours of Monday-Friday or a tendency to use the EMV service (drive-through) around noon on holidays is detected from the operation history information, A schedule table may be created from the usage trend, and when, where, and which service (ETC service or EMV service) will be predicted using the schedule table.

In this embodiment, the timing of the next service to be used is predicted based on two parameters, time and distance.
For example, as shown in FIG. 5, from the operation history information, the use of toll road A (use of ETC service) enters the toll road from entrance gate A1 at around 9:00 every day, and exit gate A2 at around 11:00. Suppose that the usage tendency of going out to the general road is detected. In addition, it is assumed that a tendency to use the restaurant B by drive-through (use of EMV service) is detected around 12:00 every day. Here, if the time in this step is 10:00, it is predicted that the exit gate A2 of the toll road A will be used after about 1 hour. That is, the next service to be used is an ETC service, and the timing is predicted to be one hour later.

  In addition, using the same operation history information, the timing for using the next service may be specified based on the elapsed time based on the service used last time. For example, as shown in FIG. 6, starting from the entrance gate A1 of the toll road A, the exit gate A2 is used after about 2 hours, and the restaurant B is used by drive through after about 1 hour. Is detected. Here, in this step, assuming that about 2 hours and 30 minutes have elapsed from the entrance gate A1 of the toll road A, it is predicted that the drive-through of the restaurant B will be used after about 30 minutes. That is, the next service to be used is predicted to be an EMV service.

  Further, using the same operation history information, the timing of using the next service may be predicted based on the travel distance based on the service used last time. For example, as illustrated in FIG. 7, the timing of using the next service may be specified from the distance between the services starting from the entrance gate A1 of the toll road A (or the position where the service is received) From that order, the timing for using the next service may be specified).

In this step, the timing for using the next service is specified based on a prediction in which a tendency is more prominently detected among prediction based on elapsed time and prediction based on travel distance.
Next, in S210, it is determined whether or not an IC card 3 suitable for the service predicted in S205 is attached to the card processing unit 17. Here, when the IC card 3 suitable for the predicted service is attached, the notification setting process is terminated. On the other hand, when the IC card 3 suitable for the predicted service is not attached, the process proceeds to S215. That is, in this step, the necessity of notification is determined based on the usage mode of the next service predicted by S205 (prediction means) and the mounting state of the IC card.

  In subsequent S215, analysis processing is performed. In the analysis processing, the operation history information accumulated in the storage unit 18 is used to analyze the manner of past attachment / detachment operation of the IC card 3 by the user. Specifically, using the operation history information, a predetermined index value for a predetermined analysis item content is calculated for each predetermined detection target. FIG. 8 shows analysis item contents, index values, and detection targets in the present embodiment.

  In the analysis process, as shown in FIG. The card error represents that the use of the service is denied due to the mounting state of the IC card 3. The IC card mounting state in which the use of the service is denied is, for example, the state where the IC card 3 required by the service is not normally mounted in the card processing unit 17 when necessary, and the expiration date of the IC card 3 It means the state that is cut. Further, the state where the IC card 3 is not normally attached means that the IC card 3 is not attached, or the IC card 3 is not properly held (inverted or wrongly attached direction, etc.).

  In analysis item 1, card error frequency is calculated as an index value for measuring how frequently card errors occur. The card error frequency is the number of times the use of the service has been rejected due to the numerator of the IC card 3, and the denominator is the total number of times the service has been used so far, expressed as a percentage (%). is there.

  In the analysis item 1, the index value is calculated for each card ID and for each service type (ETC service or EMV service). For example, when the type of service is an ETC service, the index value is calculated as the number of times the use of the service is rejected due to the mounting state of the IC card 3 (ETC card) in the use of the ETC service. By calculating the index value in this way, it is detected which service the user uses to determine whether the frequency of card errors tends to be high (or low).

  Further, in the analysis item 1, when the service used is an ETC service, the index value is calculated every time when the entrance gate is used and when the exit gate is used. For example, when the index value is calculated when the entrance gate is used, the index value is calculated as the number of times when the use of the service is rejected due to the mounting state of the IC card 3 when using the ETC service when using the numerator. Thereby, it is detected whether the frequency of occurrence of card errors tends to be high (or low) when the user uses the entrance gate or the exit gate.

  Further, in the analysis item 1, the index value is calculated for each wearing state in which use of the service is denied. For example, when the index value is calculated for the IC card 3 (ETC card) that is not installed, the number of times the use of the service is denied due to the IC card 3 (ETC card) not being installed when the ETC service is used. An index value is calculated. As a result, it is detected whether the user has a tendency to cause a card error depending on the mounting state. Further, in the use of the ETC service, a more detailed tendency is detected by calculating the index value separately when the entrance gate is used and when the exit gate is used.

  In the analysis item 2, an analysis is performed on the result of the attaching / detaching operation error. The attachment / detachment operation error means a state where the IC card 3 is not normally attached to the card processing unit 17 and a state where the expiration date of the IC card 3 has expired.

  In analysis item 2, the frequency of attaching / detaching operation errors is calculated as an index value for measuring how frequently the attaching / detaching operation errors occur. The attachment / detachment operation error frequency is a value expressed as a percentage (%) in which the numerator is the number of times an error has been detected in the IC card mounting state and the denominator is the total number of times the card has been mounted.

  In analysis item 2, the index value is calculated for each card ID. Thereby, it is detected whether the frequency at which the user causes the attachment / detachment operation error is high (or low). Further, in the analysis item 2, the index value is calculated for each state of the attaching / detaching operation error. As a result, it is detected what kind of attachment / detachment operation error the user tends to cause.

  In analysis item 3, the vehicle speed during the mounting operation is analyzed. The vehicle speed at the time of the mounting operation is a vehicle speed detected when the IC card 3 is mounted on the card processing unit 17. It is desirable that the IC card 3 is mounted on the card processing unit 17 in a state where the vehicle is stopped (or a state close to the stop as much as possible). Conversely, it can be said that it is not desirable to attach the IC card 3 to the card processing unit 17 while the vehicle is running.

  Therefore, in analysis item 3, the non-stop mounting frequency is calculated as an index value for measuring how often the IC card 3 is mounted on the card processing unit 17 when not at a stop. Non-stop mounting frequency is the number of times the vehicle speed when the IC card 3 is mounted on the card processing unit 17 exceeds 0 km (stop), and the denominator is the total number of times the card has been mounted so far. Is a value expressed as a percentage (%).

  In analysis item 3, the index value is calculated for each card ID and for each service type (ETC service or EMV service). Thereby, it is detected whether the user has a high (or low) tendency to attach the IC card 3 without stopping the vehicle. Further, when the user uses which service, a detailed tendency is detected as to whether the tendency of mounting the IC card 3 without stopping the vehicle is high (or low).

  In analysis item 4, the vehicle speed when using the service is analyzed. In the case of an ETC service, the vehicle speed when using the service is the vehicle speed detected when passing through the ETC roadside machine 21 (entrance gate and exit gate) (when a vehicle enters the communication area of the ETC roadside machine 21). Say. In the case of the EMV service, it means a vehicle speed detected when the vehicle passes through the EMV roadside machine 23 (when a vehicle enters the communication area of the EMV roadside machine 23).

  The vehicle speed when passing through the ETC roadside machine 21 is set to a legal speed of 20 km or less. Further, it is desirable that the vehicle speed when passing through the EMV roadside machine 23 is as close as possible to a stop (for example, 1 km or less per hour). Conversely, passing the ETC roadside machine 21 or the EMV roadside machine 23 at a vehicle speed exceeding these speeds is not desirable.

  Therefore, in the analysis item 4, the vehicle speed excess frequency is calculated as an index value for measuring how often the vehicle passes through the ETC roadside machine 21 or the EMV roadside machine 23 at an appropriate vehicle speed. The vehicle speed excess frequency is a value expressed as a percentage (%), where the numerator is the number of times the vehicle speed when using the service exceeds a predetermined speed, and the denominator is the total number of times the service has been used. The predetermined value is 20 km / h for the ETC service and 1 km / h for the EMV service.

  In analysis item 4, the index value is calculated for each card ID and for each service type (ETC service or EMV service). Thereby, it is detected whether the user has a high (or low) tendency to pass the installation position of the ETC roadside machine 21 or the EMV roadside machine 23 at a vehicle speed exceeding a predetermined speed when using the service. Further, a more detailed tendency is detected by calculating an index value for each service type.

  In analysis item 5, an analysis is made of the results of leaving the card. Card leaving means a state in which the IC card 3 is left in the card processing unit 17 from when it gets off to the next boarding.

  In the analysis item 5, the frequency of leaving is calculated as an index value for measuring how often the IC card 3 is left with being mounted between the time when it gets off and the time when it gets on. The neglected frequency is a value in which the numerator is the number of times the IC card 3 has been mounted in the card processing unit 17 both when the engine stop is detected and when the engine start is detected, and the denominator is the number of times the engine start has been detected so far. , Percentage (%).

  In analysis item 5, the index value is calculated for each card ID. As a result, it is detected whether the user has a high (or low) tendency to get off while leaving the IC card 3 attached to the card processing unit 17.

  In analysis item 6, an analysis is performed for a margin until the card is mounted. The margin until the card is installed means whether the IC card 3 is installed in the card processing unit 17 with a margin with respect to the timing of using the service. The margin here is expressed in hours (minutes) when prediction based on time is performed in S210, and is expressed in distance (km) when prediction based on distance is performed. The state in which the IC card 3 is mounted immediately before using the service is not a desirable state.

  Therefore, in analysis item 6, the mounting margin is calculated as an index value for measuring how often the IC card 3 is mounted in a state with a small margin with respect to the timing of using the service. The margin for mounting is the number of times the IC card 3 is mounted in the card processing unit 17 without margin for a predetermined time (or predetermined distance) with respect to the timing of using the numerator service, and the service has been used up to now with the denominator. This is a value obtained by displaying the value of the total number of times as a percentage (%).

  In analysis item 6, the index value is calculated for use of the ETC service for each card ID. As a result, it is detected which service the user uses is likely to have a high (or low) tendency to attach the IC card 3 immediately before. Further, a more detailed tendency is detected by calculating an index value for each of the entrance gate and the exit gate.

  In analysis item 7, the result of the card remounting operation is analyzed. The card remounting operation refers to performing a remounting operation after the IC card 3 is mounted in the card processing unit 17.

  In the analysis item 7, the number of times of reattachment / removal is calculated as an index value for measuring how often the remounting operation is performed. The number of reattachment / removal refers to the number of times that the IC card 3 has been attached / detached between the use of a certain service and the use of the next service.

  In analysis item 7, the index value is calculated for each card ID. Thereby, it is detected whether the user has a high (or low) tendency to repeat the mounting operation many times. That is, a tendency to repeat the operation of re-installing many times due to worrying whether it is correctly installed is detected.

  In the analysis item 8, the ETC service is analyzed with respect to the result of card mounting when the service is not used. The installation of the card when the service is not used refers to a state where the service is not used even though the IC card 3 (ETC card) is installed in the card processing unit 17. While the service is not used, the state in which the IC card 3 is mounted on the card processing unit 17 may lead to forgetting to remove the IC card 3 when getting off, and is not a desirable state.

  In the analysis item 8, the non-use wearing frequency is calculated as an index value for measuring how often the ETC service is not used even though the IC card 3 is attached. The frequency of non-use is the number of times the numerator is attached to the IC card 3 when boarding, the IC card 3 is taken out without using the service, and the passenger gets off, and the denominator is attached to the IC card 3 when boarding. This is a value expressed as a percentage (%), which is the number of times the IC card 3 has been taken out using the service and got off. As a detection method of a boarding state, the method by the detection of ACC ON (ACC signal) or the detection of engine starting is mentioned. Moreover, as a detection method of an alighting state, the method by the detection of ACC off (ACC signal) or the detection of an engine stop is mentioned.

  In analysis item 8, the index value is calculated for each card ID. Thereby, it is detected whether the user has a high (or low) tendency to keep the IC card 3 while the service is not used.

  In subsequent S220 (FIG. 4), it is determined whether or not the index value calculated in S215 is not less than a predetermined threshold for each analysis item. As described above, for each analysis item, an index value is calculated for each detection target. Here, in all the analysis items, when it is determined that all index values are less than the threshold value, this processing is terminated. On the other hand, if it is determined that at least one index value is greater than or equal to the threshold for at least one analysis item, the process proceeds to S225.

  In S225, a notification flag is set for an analysis item having an index value that is equal to or greater than a threshold value. For example, when it is determined in S220 that the index value is greater than or equal to the threshold value in analysis item 1, a notification flag for analysis item 1 is set in this step.

  In succeeding S230-S250, the alerting | reporting mode at the time of alerting | reporting is set about the analysis item to which the alerting | reporting flag was set by S225. An example of the alerting | reporting aspect in this embodiment is shown in FIG. Here, when a plurality of index values are calculated for each detection target in one analysis item as in analysis item 1, a case where the plurality of index values are equal to or greater than a threshold value may occur. In this case, the notification mode is set according to S230 to S250 for the detection target having the index value with the largest degree of exceeding the threshold. For example, in the analysis item 1, it is assumed that both the index value when the detection target is the ETC service and the index value when the detection target is the EMV service are equal to or greater than a predetermined threshold value for each index value. At this time, for example, when the index value for which the ETC service is detected is larger than the threshold value for the EMV service, the mode in which the ETC service is the detection target in S230 to S250. Set.

  In S230, a notification content (notification message) is set as a notification mode. The notification message is set for each analysis item. Furthermore, the notification message is set according to the calculated index value as necessary. A specific example of the notification message will be described later.

  Next, in S235, notification timing (notification timing) is set. The notification timing depends on the analysis item, when a specific event is detected, when a predetermined event occurs, for a predetermined time (or before a predetermined distance) for using the next service, as early as possible, etc. Set to The notification timing is set based on the elapsed time when the timing prediction for the next service use performed in S210 is based on the elapsed time, and is set based on the travel distance when based on the travel distance.

  In subsequent S240, a reference for performing notification is set. That is, whether to perform notification based on elapsed time (time reference) or to perform notification based on travel distance (distance reference) is set. Here, when the prediction about the timing of using the next service performed in S210 is based on the elapsed time, the reference for notification is set as the time reference. On the other hand, when the prediction about the timing of using the next service is based on the travel distance, the reference for reporting is set as the distance reference.

  Next, in S245, the presence or absence of stop priority setting is set. The stop priority setting is a setting as to whether or not to give priority to notification when the vehicle stops. It is desirable that the notification is performed while the vehicle is stopped so that the user can concentrate on the driving operation. In this embodiment, the stop priority setting is set to “present”.

  In subsequent S250, presence / absence of immediate notification setting is set. Here, if it is set to notify as soon as possible in S235, the immediate notification setting is set to “present”. On the other hand, if it is not set to notify as soon as possible in S235, the immediate notification setting is set to none.

Next, in S255, the contents of the setting performed in S230-S250 are stored in the storage unit 18 as notification setting data, and the notification setting process is terminated.
[2.3 Notification processing]
Next, the notification process will be described using the flowchart shown in FIG. In S305, it is determined whether there is an analysis item for which the notification flag is set. If there is no analysis item for which the notification flag is set, the notification processing is terminated. On the other hand, when the notification flag is set for at least one analysis item, the process proceeds to S310.

In subsequent S310, notification setting data (see S255) is read from the storage unit 18 for the analysis item for which the notification flag is set.
Next, in S315, it is determined whether or not the immediate notification setting is set for the analysis item for which the notification flag is set. If the immediate notification setting is set to “Yes”, the process proceeds to S350. On the other hand, if the immediate notification setting is not set, the process proceeds to S320.

  In continuing S320, it is determined whether the reference | standard which performs alerting | reporting is set to the time reference | standard. If the time reference is not set, that is, if the distance reference is set, the process proceeds to S330. On the other hand, when the time reference is set, the process proceeds to S325.

  Next, in S325, it is determined whether or not the notification timing (distance) set in S235 has been reached. For example, when the setting is 5 km before the timing (position) of using the service, it is determined whether or not the setting has reached 5 km. If the set distance (position) has been reached, the process proceeds to S335. On the other hand, if the set distance (position) has not been reached, the notification process is terminated.

  In S330, it is determined whether or not the notification timing (elapsed time) set in S235 has been reached. For example, if the setting is 5 minutes before the use of the service, it is determined whether or not 5 minutes has been reached. Here, when it is determined that the set elapsed time has not been reached, this processing is terminated. On the other hand, when it is determined that the set elapsed time has been reached, the process proceeds to S335.

  In S335, it is determined whether or not the stop priority setting is set to exist. If the stop priority setting is set to none, the process proceeds to S350. On the other hand, if the stop priority setting is set to be present, the process proceeds to S340.

  In continuing S340, it is determined whether it is stopping. Here, stopping means that the vehicle speed is 0 km / h. When it is determined that the vehicle is stopped, the process proceeds to S350. On the other hand, when it determines with not stopping, it transfers to S345.

  Next, in S345, it is determined using the information in the map database 333 whether or not there is a signal until the next service use timing (position or elapsed time) is reached. Here, when it is determined that a signal is present, the notification process is terminated. On the other hand, if it is determined that there is no signal, the process proceeds to S350.

  In S350, the notification message set in S230 is notified using the HMI unit 16. In subsequent S355, the set notification flag is reset. Then, this process ends.

[3. Action]
Next, an example of the notification mode of each analysis item will be described as an operation of the vehicle-mounted device 10 (see FIGS. 8 and 9).

  For analysis item 1, if the index value (card error frequency) when the detection target is the ETC service is equal to or greater than a predetermined threshold, a notification message “Please check the ETC card.” Is notified. The Further, when the index value (card error frequency) when the detection target is an ETC service and the expiration date is equal to or greater than a predetermined threshold, a notification message “Please check the expiration date of the ETC card.” Is notified. Then, the notification is performed at a predetermined notification timing before the timing of using the next ETC service predicted in S205.

  For the analysis item 2, when the index value is equal to or greater than a predetermined threshold, a notification message “Please check the card.” Is provided. In particular, when the index value (attachment / detachment operation error frequency) when the detection target is expired is equal to or greater than a predetermined threshold, a notification message “Please check the expiration date of the card” is notified. . This notification is performed at the timing when the start of the engine is detected.

  For analysis item 3, when the index value is equal to or greater than a predetermined threshold, a notification message “Insert card while stopped” is issued. This notification is performed at a predetermined notification timing before the timing of using the next service (ETC service and EMV service) predicted in S205.

  Further, in the present embodiment, when the index value calculated in S215 is a value close to 100% (for example, 99% or more), it is the predetermined vehicle speed or more when the IC card 3 is mounted. Is detected, the immediate notification setting is set to be present in S250, and a notification message is notified at the earliest possible timing.

  For the analysis item 4, when the index value is equal to or greater than a predetermined threshold value, a notification message of “let's pass at a safe speed when using the service” is given. This notification is performed at a predetermined notification timing before the timing of using the next service (ETC service and EMV service) predicted in S205.

  For analysis item 5, when the index value is equal to or greater than a predetermined threshold (for example, 20%), the index value is equal to or less than a first auxiliary threshold (for example, 50%) that is greater than the predetermined threshold (first case) ), And a notification message “Card is left” is issued. In addition, when the index value is greater than the first auxiliary threshold and less than or equal to the second auxiliary threshold (eg, 90%) greater than the first auxiliary threshold (second case), and the index value is the second If it is larger than the auxiliary threshold (third case), a notification message “Please be careful not to be stolen” is issued.

  Analysis item 5 is performed at the timing when the engine stop is detected. However, when the engine stop is detected, for example, the frequency of every time in the case of the first case, once every two times in the case of the second case, and once every 10 times in the case of the third case. Then, notification is performed. Depending on the user, there is a strong tendency to get off with the IC card 3 mounted, as in the second case and the third case. In such a case, notification every time makes the user feel bothersome. In particular, in the case of the user of the third case, it is presumed that it is becoming habitual in consideration of getting off with the IC card 3 mounted. Therefore, in this embodiment, in order to respect the user's habits and not cause the user to feel bothered, the notification frequency is set particularly low for the user corresponding to the third case.

  For the analysis item 6, when the index value is equal to or greater than a predetermined threshold, a notification message “ETC card should be inserted in advance with a margin” is notified. This notification is performed at a predetermined notification timing before the timing at which engine start is detected and the timing at which the next ETC service is predicted in S205.

  For the analysis item 7, when the index value is equal to or greater than a predetermined threshold, a notification message “Card is normal” is given. This notification is performed at a predetermined notification timing before the timing at which the next attaching / detaching operation set (predicted) in S235 is performed. Here, the timing at which the next attachment / detachment operation is performed is also changed by the increase / decrease of the index value. That is, if the number of times of performing the detachment operation is reduced, the frequency of the notification timing is reduced.

  For the analysis item 8, when the index value is equal to or greater than a predetermined threshold value, a notification message “not insert a card when not using the service” is notified. This notification is performed at the timing when the engine start is detected, and at a predetermined notification timing that is set (predicted) in S235 and before the timing when the IC card 3 is first mounted after the engine is started.

[4. effect]
As described above, in the present embodiment, the past IC card 3 attachment / detachment operation mode by the user is accumulated as operation history information, the operation history information is statistically analyzed, and the notification mode according to the analysis result is used. Notification. For this reason, notification is performed in a notification mode according to the user. Therefore, compared with the case where it alert | reports uniformly irrespective of the aspect of the past attachment / detachment operation by a user, the troublesomeness which a user feels can be reduced.

  Specifically, in the notification control process, information (for example, information related to analysis item 1) indicating that the use of the service is denied due to the mounted state of the IC card 3 is accumulated as operation history information. For this reason, notification is performed in a notification mode corresponding to the cause of the denial of service use. In other words, according to the tendency that the use of the service is refused, such as prompting the user to install the IC card 3 or checking the expiration date of the IC card 3, the service is not refused before using the service. It is possible to perform specific notification that prompts the user to attach and detach.

  In the notification control process, information indicating that the attachment / detachment operation has not been performed by a predetermined time (for example, information related to the analysis item 6) is accumulated as operation history information. For this reason, the notification is performed in such a manner as to prompt the detachment operation to be performed by a predetermined time. That is, it is possible to perform a specific notification that prompts the user to attach the IC card 3 to the card processing unit 17 with a margin.

  Furthermore, in the notification control process, information (for example, information related to the analysis item 2) indicating that the IC card 3 is loaded in the card processing unit 17 in an incorrect state is accumulated as operation history information. For this reason, notification is performed in a manner corresponding to the cause of the IC card 3 being mounted in the card processing unit 17 in an incorrect state. That is, it is possible to notify that the IC card 3 is mounted on the card processing unit 17 in an appropriate state.

  In the present embodiment, in the notification setting process, based on the operation history information, an index value representing the degree of suitability of the attachment / detachment operation performed in the past is calculated as an analysis result. And it alert | reports by the alerting | reporting aspect according to this analysis result. Thereby, it is possible to perform notification that is more useful to the user.

  Furthermore, in this embodiment, in the notification setting process, the necessity of the notification process is determined according to the analysis result of the operation history information. That is, since it is not notified when it determines with alerting | reporting unnecessary, the troublesomeness which a user feels can be reduced compared with the case where alerting | reporting is performed uniformly.

  In the present embodiment, in the notification process, it is determined whether or not the vehicle is stopped, and notification is performed when it is determined that the vehicle is stopped. Thereby, compared with the case where it alert | reports during driving | running | working of a vehicle, attachment / detachment operation of IC card 3 can be made difficult to be performed during driving | running | working.

  In the present embodiment, in the notification setting process, a plurality of notification modes having different notification frequencies are set, and the notification processing is performed in the notification mode according to the analysis result. For example, in analysis item 5, notification is made every time to a user who has a low tendency to get off with the IC card 3 attached (first case), and the user who has a strong tendency (second case and third case). In this case, notification is performed less frequently. Thereby, it can alert | report in the aspect considered more effective according to a user's tendency.

  Furthermore, in this embodiment, in the notification setting process, a plurality of notification messages having different notification contents are set, and the notification process is performed using the notification message corresponding to the analysis result. For example, as shown in the analysis item 5, with respect to an aspect in which the IC card 3 is left attached when getting off the vehicle, a notification message “Please be careful not to forget to remove the card” may be uniformly set in the conventional apparatus. It was general. On the other hand, in this embodiment, it sets so that a different alert message may be alert | reported by the strength of the tendency to leave it with mounting | wearing. That is, for a user who has a low tendency to leave it attached, a notification message “card remains” is set. On the other hand, for users who have a strong tendency to leave while wearing, include more specific content that indicates why it should not be left, such as "Please be careful not to be stolen." Set a notification message. Thereby, compared with the case where it alert | reports uniformly, a user can be alerted more effective attention.

  In this embodiment, in the notification control process, the service usage history is stored as event information (service history information) in S165 (service history storage means), and is stored in S205 (prediction means) in S165. Statistically analyze event information and predict the next service usage. Then, the notification setting process determines whether or not the notification process is necessary based on the usage mode of the next service predicted in S205 and the mounting state of the IC card 3. Thereby, compared with the case where it alert | reports uniformly irrespective of the utilization aspect of the next service, the troublesomeness which a user feels can be reduced.

  Furthermore, in the present embodiment, in the notification setting process, in S205, a service to be used next time is predicted from among a plurality of types of the services with different types of required IC cards 3. In S210, notification processing is performed on the condition that the IC card 3 necessary for using the next service predicted in S205 is not attached to the card processing unit 17. According to this, since unnecessary notification can be reduced while performing effective notification, compared with the case where notification is uniformly performed regardless of the type of the IC card 3, it is possible to reduce annoyance felt by the user. .

  In the present embodiment, in the notification setting process, the notification process is performed at a predetermined notification timing before the timing of using the next service predicted by S205 (prediction means). Thereby, about the user's attachment / detachment operation of the IC card 3, notification (post-warning) is not performed after the user performs an undesired operation, but before the user performs an undesired operation (pre-warning). It can be carried out.

  Furthermore, in this embodiment, the notification timing is specified based on the elapsed time based on the previous service in the notification setting process. Thereby, the notification based on the elapsed time can be performed. Further, for example, even when the navigation device 13 is not provided, the notification timing can be specified.

  In the present embodiment, the notification timing is specified based on the travel distance based on the previous service in the notification process. Thereby, the notification based on the travel distance can be performed. Further, for example, even when the timekeeping function is not provided, the notification timing can be specified.

  In the present embodiment, the operation history information is acquired for each card ID of the IC card 3. As a result, even when a vehicle is used by a plurality of people such as a company car, the user who uses the vehicle can be identified by the card ID of the IC card 3. Based on the operation history information, notification according to the mode of attachment / detachment operation by the user can be performed.

In this case, since the map database 333 is not provided, in S210, the service to be used next is predicted based on the elapsed time based on the service used last time. In S240, the reference for notification is set as the time reference, and in S245, the stop priority setting is set to none.

  (E) In the above embodiment, in the notification setting process, the service used by the vehicle is predicted from the operation history information for each time zone, every day of the week, every day, every week, every month, etc. Prediction is not limited to these. For example, a raindrop sensor and an illuminance sensor as vehicle sensors may be provided, and service prediction using these may be performed.

  That is, during the history writing process in the notification control process, it is detected by the raindrop sensor whether or not it was raining when the event occurred, and the detection result is stored as event information. Further, it is detected by an illuminance sensor whether or not the event occurred at night (it may be detected that it is night using a time measuring function), and the detection result is stored as event information. Then, using the operation history information including these event information, for example, a service frequently used on a rainy day or a service frequently used at night regardless of the date and time, and a service to be used next May be predicted.

  Then, in the above-mentioned “services used by time of day, day of week, day, week, month”, “services used on rainy days”, and “services used at night”, the next service is predicted. The priority order prediction to be used may be determined in descending order of tendency.

  (F) In the above-described embodiment, the configuration for predicting the usage mode of the next service is illustrated. However, the configuration is not limited to this, and the configuration may be such that the usage mode of the next service is not predicted.

  (G) In the above embodiment, in the notification process, the notification is performed in a state where the vehicle is completely stopped (0 km / h). However, the notification timing is not limited thereto. For example, you may comprise so that it may alert | report when it becomes very low speed (for example, 1 km / h).

  (H) In the above embodiment, in the notification setting process, the service to be used next is predicted using the operation history information in S205. However, as a result of analyzing the operation history information, when a remarkable tendency cannot be grasped, the prediction may not be performed. Thereby, the troublesomeness which a user feels by notifying based on prediction with low accuracy can be reduced.

  (I) Although an example of setting contents in the notification setting process has been described in the above embodiment, the setting contents are not limited to this. For example, an air temperature sensor for detecting the temperature outside the vehicle is provided, and when the detected outside air temperature exceeds a predetermined value, if the IC card 3 remains attached to the card processing unit 17, for example, the engine is stopped. In doing so, it may be set to notify that “please remove the card because there is a risk of deformation due to a rise in outside air temperature”. As a result, for example, in a season when the outside air temperature is high, it is possible to prevent the card from being bent or damaged by leaving the IC card 3 inserted in the card processing unit 17.

  In addition, for example, to a user who is presumed to be left with the IC card 3 attached to the card processing unit 17 like the user classified as the third case in the analysis item 5 of the above embodiment. On the other hand, when the detected outside air temperature exceeds a predetermined value, the above-described notification may be performed. In this way, it may be set to perform only the minimum necessary notification. As such a setting, in addition to the setting for notifying the user to remove the IC card 3 in order to prevent the deformation due to the rise in the outside air temperature as described above, the brightness outside the vehicle is detected by the illuminance sensor. For example, a setting for prohibiting a warning for prompting a card operation when dark is used.

  (J) In the above embodiment, in the notification setting process, the notification mode is set in S230, but the items to be set are not limited to the above-described contents. In addition, the volume (notification volume) when performing notification using the HMI unit 16 and the content of the image to be displayed may be set.

  (K) In the said embodiment, as shown in FIG.8 and FIG.9, although the analysis item was set and the alerting | reporting aspect about each analysis item was set, it does not restrict to this. For example, in the above-described embodiment, the number of reattachment / removal times is set as the index value of the analysis item 7, but instead, the index value is set as a time interval for mounting the card, and the time interval is within a predetermined time. You may set so that it may alert | report. As described above, the content of the analysis item, the index value, the detection target, the notification mode, and the like can be variously set according to the user's action (attachment / detachment operation) whose tendency is to be understood.

  (L) In the above embodiment, in the notification control process, after executing the process of S105, it is determined whether or not the current value is a service area of a toll road. 3 may be added. If the IC card 3 is not attached, a process for notifying the user to attach the IC card 3 may be added.

  (M) In the above-described embodiment, the device having a timekeeping function for acquiring the date and time is provided like the navigation device 13, but the device having such a timekeeping function may not be provided. For example, date information in the event information may be acquired by communication between the wireless communication unit 14 and the roadside device 2 using a timekeeping function provided in the roadside device 2.

  (N) In the above-described embodiment, the engine start and stop are determined according to the on / off state of the ACC signal. However, the present invention is not limited to this. For example, the engine may be determined to have started when the period during which the ACC signal is on continues for a predetermined period or longer. Thereby, when the ACC signal is turned on to operate the power window, the car navigation system, and the audio for a while, it can be determined that the engine is not started.

  (O) In the above embodiment, the vehicle-mounted device 10 is configured to determine whether the engine is started and stopped by the control unit 15, but is not limited thereto. The vehicle-mounted device 10 may be configured such that components other than the control unit 15 determine the start and stop of the engine using the ACC signal. Moreover, the onboard equipment 10 may be comprised so that engine starting and a stop may be judged using signals other than an ACC signal.

  (P) In addition to the vehicle-mounted device 10 described above, the present invention includes a system including the vehicle-mounted device 10 as a constituent element, a program for causing a computer to function as the vehicle-mounted device 10, a medium storing the program, and a vehicle communication method It can be realized in various forms.
