Description

  The present invention relates to an in-vehicle device for narrow area communication used in an ETC (Electronic Toll Collection) system of ITS (Intelligent Transport System).

  In recent years, road-to-vehicle communication services using DSRC (Dedicated Short-Range Communication) have begun to spread. As a road-to-vehicle communication service using this DSRC, there is an ETC service. The ETC service is a service for automatically collecting tolls on toll roads. Moreover, in the ETC system for realizing the ETC service, wireless communication, that is, road-to-vehicle communication, is performed between the vehicle-mounted device attached to the vehicle and the roadside device installed at the toll gate. And a toll collection process is performed by transmitting and receiving necessary information between the vehicle-mounted device and the roadside device.

  Here, an ETC payment card, which is an IC card dedicated to ETC payment, is used for toll payment. This ETC payment card is used by being inserted into a card slot provided in the vehicle-mounted device. In order to use the ETC service, ETC setup processing of the vehicle-mounted device is required in advance. The ETC setup process is a process for preregistering initial information such as vehicle information necessary for an ETC service provided by an expressway operator in the vehicle-mounted device. If this ETC setup process is not completed, the vehicle-mounted device cannot perform road-to-vehicle communication in the ETC system, and the user cannot use the ETC service.

  Specifically, the ETC setup process is executed by inserting an ETC setup card, which is an IC card in which ETC setup information is previously written, into a card slot of the vehicle-mounted device. The ETC setup information is ETC on-board device information, ETC security information that is encryption key information for encrypted communication, and the like.

  With regard to this ETC setup process, for example, in conventional vehicle-mounted devices as shown in Patent Documents 1 and 2, ETC setup information is read from the ETC setup card by the CPU. Then, the setup information is stored in an SAM (Security Application Module) for cryptographic processing. Thereby, the ETC setup process is completed.

  For example, in a conventional vehicle-mounted device as shown in Patent Document 3, an IC card in which an initialization-dedicated file is stored in advance in a card slot of the vehicle-mounted device is inserted at the stage of shipment inspection after the vehicle-mounted device is manufactured. Then, when the initialization dedicated file is read by the CPU, the settings related to the ETC setup process are deleted.

  Here, in recent years, among the services using DSRC, in addition to the ETC service, for example, a service that performs payment at a parking lot, a gas station, a drive-through, or the like, or a service that performs logistics management, etc. Narrow-area communication application services (non-ETC services) are being put into practical use. Therefore, among road-to-vehicle communication systems using DSRC, there is a need for an in-vehicle device for narrow area communication that can provide both an ETC service and a non-ETC service.

  Hereinafter, in the present specification, the above-mentioned narrow area communication application service is simply described as a DSRC service. Moreover, the narrow area communication application system which is a road-to-vehicle communication system other than the ETC system among road-to-vehicle communication systems using DSRC is simply described as a DSRC system.

  Here, when using the DSRC service, a DSRC service card (DSRC payment card), which is an IC card such as a credit card, is used. This DSRC service card is an IC card different from the ETC payment card. Therefore, in order to use the DSRC service, a setup process different from the ETC setup process, that is, a DSRC setup process is required. If this DSRC setup process is not completed, the vehicle-mounted device cannot perform road-to-vehicle communication in the DSRC system, and the user cannot use the DSRC service.

  This DSRC setup process is executed by the CPU of the vehicle-mounted device when a DSRC setup card, which is an IC card in which DSRC setup information is written in advance, is inserted into the card slot of the vehicle-mounted device. The DSRC setup information is DSRC on-board device information and DSRC security information that is encryption key information for encrypted communication. The DSRC OBE information is different from the ETC OBE information, and the DSRC security information is also information different from the ETC security information.

  Further, the DSRC setup process is completed when the CPU of the vehicle-mounted device reads the DSRC setup information from the DSRC setup card and stores the DSRC setup information in the SAM. Therefore, in order for the vehicle-mounted device to perform road-to-vehicle communication of both the ETC system and the DSRC system, it is necessary to execute both the ETC setup process and the DSRC setup process.

  Here, in the in-vehicle device in which both the ETC setup processing and the DSRC setup processing are incomplete (unprocessed), only the DSRC setup processing is executed, and when the DSRC setup processing is successful, the state of the on-vehicle device is: The DSRC setup process has been completed, and the ETC setup process has not been completed.

  In addition, in the in-vehicle device in which both the ETC setup process and the DSRC setup process are incomplete, both the ETC setup process and the DSRC setup process are executed, the ETC setup process fails, and only the DSRC setup process succeeds. The state of the vehicle-mounted device is a state in which the DSRC setup process has been completed and the ETC setup process has not been completed.

  The vehicle-mounted device in such a state can use only the DSRC service, and the ETC service that has been prevalent before the DSRC service cannot be used. As a result, a user who mainly intends to receive the ETC service cannot receive the ETC service, which is not preferable in the operation of the ETC service and the DSRC service.

  In addition, in the conventional vehicle-mounted device as shown in Patent Documents 1 and 2, only the IC card related to the ETC system is accepted, and when other cards are inserted into the card slot of the vehicle-mounted device, the sound output of the vehicle-mounted device is output. A card abnormality notice is issued from the means. Due to such a configuration, the ETC setup process and the DSRC setup process cannot be properly executed. Moreover, in the conventional vehicle-mounted device as shown in Patent Document 3, the completed state of the setup process is initialized according to the completion state of the setup process, but the execution of the DSRC setup process is not limited.

  The present invention has been made to solve the above-described problems, and the setup processing in the automatic road toll collection system has not been completed, and the setup processing in the narrow area communication application system has been completed. It aims at obtaining the vehicle-mounted device for narrow area communication which can prevent this.

  The on-vehicle device for narrow-area communication according to the present invention includes a road automatic toll collection system and a narrow-area communication application system that is a road-to-vehicle communication system other than the road automatic toll collection system among road-to-vehicle communication systems using narrow-area communication. With the completion of the setup process based on the setup information corresponding to each, road-to-vehicle communication in the road-to-vehicle communication system corresponding to the setup information becomes possible, and information used for services by the road-to-vehicle communication system An IC card in which IC main storage information, which is one of certain service information and setup information, and identification information for identifying the type can be read in advance, and the type of IC card to be read Different processing is performed every time, and the IC main memory information and identification information stored in the IC card are read. In addition, the IC card reader that identifies the type of the IC card based on the read identification information, and the IC card reader identified that the type of the IC card is for setup processing in the automatic road toll collection system A setup processing unit for executing a setup process in the automatic road toll collection system based on the IC main memory information read from the IC card by the IC card reading unit. When the type of IC card is identified as being for setup processing in a narrow-area communication application system, when the setup processing in the automatic road toll collection system has been completed, the IC card reader reads the IC card Based on the IC main memory information read from the And executes the setup process.

  According to the vehicle-mounted device for narrow area communication of the present invention, when the IC card reader identifies that the type of the IC card is for setup processing in the narrow area communication application system, the automatic road toll collection system When the setup process of the narrow area communication application system is completed by the setup processing unit, the setup process in the automatic road toll collection system is not completed. It is possible to prevent the setup process from being completed.

The best mode for carrying out the present invention will be described below with reference to the drawings.

  The ETC setup execution result determination means 25 executes an ETC setup status determination process. The ETC setup status determination process is a process for monitoring the processing content of the ETC setup execution unit 24 and determining the execution result of the ETC setup process by the ETC setup execution unit 24, that is, the success or failure of the ETC setup process.

  The ETC setup status determination means 26 checks whether or not ETC setup information is stored in the SAM 9 and determines whether or not the ETC setup process has been completed (incomplete). That is, when it is confirmed that the ETC setup information is stored in the SAM 9, the ETC setup status determination unit 26 determines that the ETC setup process has been completed. On the other hand, when it is confirmed that the ETC setup information is not stored in the SAM 9, the ETC setup status determination unit 26 determines that the ETC setup is incomplete.

At this time, when the ETC setup process fails, the DSRC setup information erasing means 30 initializes the setting related to the DSRC setup in the DSRC on-vehicle device 1. Other configurations are the same as those in the first embodiment.

  Next, the operation of the vehicle-mounted device control unit 4 when the IC card 16 is inserted will be described. 9 and 10 are flowcharts showing the operation of the vehicle-mounted device control unit 4 of FIG.

  Then, in FIG. 10, the onboard equipment control unit 4 executes a DSRC setup process (step S601). And the onboard equipment control unit 4 confirms whether the DSRC setup process was successful (step S602). At this time, when confirming the success of the DSRC setup process, the vehicle-mounted device control unit 4 executes the ETC setup process and confirms whether the ETC setup process is successful (steps S602 and S603).

  And the onboard equipment control unit 4 confirms whether the ETC setup process was successful (step S604). At this time, when the onboard equipment control unit 4 confirms the success of the ETC setup process, the HMI unit 6 notifies the user that the DSRC setup process and the ETC setup process have been successful (step S605). And operation | movement of the onboard equipment control unit 4 when the IC card 16 is inserted is complete | finished.

  On the other hand, the onboard equipment control unit 4 deletes the DSRC setup information stored in the SAM 9 when the failure of the ETC setup process is confirmed (NO direction in step S604), and initializes the settings related to the DSRC setup (step S606). . And the onboard equipment control unit 4 notifies a user from the HMI part 6 that the DSRC setup process and the ETC setup process failed (step S607). And operation | movement of the onboard equipment control unit 4 when the IC card 16 is inserted is complete | finished.

  On the other hand, when the onboard control unit 4 confirms that the DSRC setup process has failed (NO in step S602), the HMI unit 6 notifies the user that the DSRC setup process and the ETC setup process have failed (step S607). ). And operation | movement of the onboard equipment control unit 4 when the IC card 16 is inserted is complete | finished. Other operations are the same as those in the first embodiment.

  Here, in the conventional vehicle-mounted device as shown in Patent Document 3, the setup related to the DSRC setup process is initialized by reading the setup initialization data from the DSRC setup card. For this reason, even when the ETC setup card is inserted, the settings relating to the DSRC setup process are not initialized.
