  The present invention relates to a vehicle-mounted device, a control method thereof, and a program, and more particularly, to a vehicle-mounted device used in an automatic toll collection system on a toll road and capable of mounting an IC card, and a control method and program thereof.

  On toll roads such as expressways, automatic toll collection systems (ETC, etc.) that automatically collect tolls by wireless communication between roadside equipment installed at toll booths and on-board equipment mounted on automobiles, etc. Electronic Tool Collection) is used.

  An on-board device (ETC on-vehicle device) that can use the ETC service is equipped with an IC card for collecting charges. The ETC on-board device reads data from the mounted IC card when passing through the entrance toll gate (when entering the toll road) and when passing through the exit toll gate (when leaving the toll road), and this is read by the roadside device. And the predetermined data is again sent to the ETC on-board unit on the roadside device side. Data sent to the ETC on-board unit is written to the IC card. Data such as an entry place stored in the IC card when entering the toll road is read out when leaving the toll road, and a toll is calculated based on the data on the entry place and the exit place.

  In general, when an ETC service user (user) takes a break in a service area on a toll road, the IC card is removed from the ETC on-board device to prevent theft, and after the break, the IC card is inserted before the start of driving. Reinsert into However, if the user holds a plurality of IC cards such as credit cards, there is a case that after returning from the break, an IC card different from the IC card inserted at the time of passing through the entrance toll gate is erroneously inserted. is there.

  When a different IC card is inserted into the ETC on-board unit, the vehicle cannot pass through the exit toll booth, which may cause traffic jams at the exit toll booth. For this reason, there is a demand for a technique for collating the IC card inserted when passing through the entrance toll gate with the IC card inserted again into the ETC on-board unit.

  In Patent Document 1, the ID information of the IC card that was inserted into the ETC on-board unit at the roadside machine at the entrance toll gate is recorded in the ETC on-board unit, and the ID information of the IC card that is inserted into the ETC on-board unit again A technique for reading and comparing with a roadside machine at a certain place is described. If a different IC card is inserted in the comparison and verification, an alarm is generated to alert the user.

  Patent Documents 2 and 3 describe techniques for collating usage information held in an IC card with usage information held in an ETC on-vehicle device. If the usage information does not match in the collation, information notifying the erroneous insertion of the IC card is output to alert the user.

  According to the on-vehicle device, the control method, and the program of the present invention, it can be easily detected that an erroneous IC card is inserted into the ETC on-vehicle device.

  Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a block diagram showing an in-vehicle device according to an embodiment of the present invention together with an IC card. The vehicle-mounted device 10 is an ETC vehicle-mounted device used for an automatic toll collection system (ETC) on a toll road, and an IC card 20 can be mounted (inserted). The vehicle-mounted device 10 includes a wireless communication unit 11, an antenna 12, a card slot 13, an information recording unit 14, a control unit 15, a display unit 16, and a buzzer 17. The control unit 15 is configured as a part of a computer controlled by a program, and has a function of controlling the wireless communication unit 11, the information recording unit 14, and the like.

  The IC card 20 has a shape that can be inserted into the vehicle-mounted device 10, and the ETC service can be used by being inserted into the vehicle-mounted device 10. The IC card 20 has an information recording unit 21 for recording information such as an account number, deposit information, and withdrawal information necessary for using the ETC service. The information recording unit 21 further includes a card ID storage unit 21a that stores an ID (card ID) of the IC card 20 as a part thereof.

  The radio communication unit 11 of the vehicle-mounted device 10 is controlled by the control unit 15 and performs radio communication with the roadside radio apparatus (roadside machine) installed at the entrance toll gate or the exit toll gate via the antenna 12. When wireless communication is established, the control unit 15 detects that the vehicle has entered the toll road through the entrance toll gate, and that the vehicle has exited from the toll road through the exit toll gate. The card slot 13 reads the card ID of the IC card 20 inserted in the vehicle-mounted device 10.

  The information recording unit 14 includes a flag storage unit 14a, an in-vehicle device ID storage unit 14b, and a card ID storage unit 14c. The flag storage unit 14a stores a flag that is set or reset by the control unit 15 when the wireless communication is established. The flag is set when entering the toll road from the entrance toll gate (when passing through the entrance toll gate), and reset when leaving the toll road via the exit toll gate (when passing through the exit toll gate) Is done. The on-vehicle device ID storage unit 14b stores an on-vehicle device ID unique to the on-vehicle device 10.

  The card ID storage unit 14c is controlled by the control unit 15 and stores the card ID of the IC card 20 read in the card slot 13 when the flag is set, and is stored when the flag is reset. Discard the card ID.

  For example, when the power is turned on or when the IC card 20 is newly inserted, the control unit 15 collates the card ID if the flag is set in the flag storage unit 14a. In the verification of the card ID, the card ID of the IC card 20 stored in the card ID storage unit 14c is read in the card slot 13 when the power is turned on or when the IC card 20 is newly inserted. Comparison is made with the card ID of the IC card 20 that has been taken out. When the controller 15 detects a mismatch between the card IDs by collating the card IDs, the controller 15 controls the display unit 16 and the buzzer 17 to generate a warning.

  The display unit 16 is, for example, an LCD (Liquid Crystal Display). When the control unit 15 is controlled to generate a warning, the IC card 20 inserted in the vehicle-mounted device 10 is inserted when passing through the entrance toll gate. A message indicating that it is different from the IC card 20 is displayed. When the buzzer 17 is controlled by the control unit 15 to generate a warning, the buzzer 17 sounds to indicate that fact.

  Hereinafter, with reference to FIG. 2, the operation when the vehicle-mounted device 10 uses the ETC service on a toll road will be described. First, the control unit 15 starts operating when the power is turned on, and reads the card ID of the IC card mounted on the vehicle-mounted device 10 (step S1).

  If insertion of an IC card is detected with the power on (step S2), the control unit 15 executes the process of step S1 and reads the card ID of the IC card. The interrupt process of step S2 occurs when an ETC service user (user) inserts an IC card after the vehicle-mounted device 10 is turned on. On the other hand, when the user has inserted the IC card before the vehicle-mounted device 10 is turned on, the control unit 15 immediately executes the process of step S1 when the power is turned on.

  Next, the control unit 15 determines whether or not a flag is set in the flag storage unit 14a (step S3). When the flag is set in step S3 (Y), the control unit 15 stores the card ID of the IC card 20 that has been inserted when passing through the entrance toll gate, which is stored in the card ID storage unit 14c of the vehicle-mounted device 10. Is read (step S4). On the other hand, if the flag is not set in step S3 (N), the control unit 15 proceeds to step S9 and waits.

  Following the processing in step S4, the control unit 15 collates the card ID read in step S1 with the card ID when passing through the entrance toll gate read in step S4 (step S5). Here, when the shape of the IC card 20 is the same as the shape of other IC cards used in transportation such as trains and buses, credit cards, etc., and the user has a plurality of IC cards, Incorrect insertion of an IC card may occur. For example, when the user temporarily removes the IC card 20 from the vehicle-mounted device 10 during a break in a toll road service area and inserts the IC card again after the break, it is different from the IC card 20 that was previously inserted. An IC card may be inserted.

  When a mismatch between the card IDs is detected in step S5 (N), the control unit 15 controls the display unit 16 and the buzzer 17 to generate an alarm (step S6). The warning may be either a message displayed on the display unit 16 or a warning sound by the buzzer 17 or both. Further, the warning not only simply notifies the user that a mismatch between the card IDs of the two has been detected, but also prompts the user to insert the IC card 20 inserted when passing through the entrance toll gate. May be.

  On the other hand, when the coincidence of both card IDs is detected in step S5 (Y), the control unit 15 shifts to a standby state, and wireless communication is established between the roadside device installed at the exit tollgate and the vehicle-mounted device 10. And waits until the exit from the toll road is detected (step S7). Next, when exit is detected in step S7 (Y), the control unit 15 resets the flag in the flag storage unit 14a, and further discards the card ID stored in the card ID storage unit 14c of the vehicle-mounted device 10. (Step S8).

  Subsequently, the control unit 15 shifts to a standby state, and waits until wireless communication is established between the roadside device installed at the entrance toll gate and the vehicle-mounted device 10 and entry to the toll road is detected (step) S9).

  Next, when entry is detected in step S9 (Y), the control unit 15 sets a flag in the flag storage unit 14a, and further from the card ID storage unit 21a of the IC card 20 inserted in the card slot 13 to the card. The ID is read out and stored in the card ID storage unit 14c of the vehicle-mounted device 10 (step S10). Then, the control part 15 transfers to a standby state, and waits until it detects the exit from a toll road (step S7).

  In the vehicle-mounted device 10 of the present embodiment, for example, when the IC card 20 is removed after passing through the entrance toll gate and inserted again by the processing in steps S1 to S6, the same IC card 20 as when passing through the entrance toll gate is installed. Whether it is inserted or not can be communicated to the user. Therefore, even when the user has a plurality of IC cards, it can be easily detected that an incorrect IC card is inserted into the vehicle-mounted device 10. As a result, the user can comfortably use the ETC service.

  The vehicle-mounted device of this embodiment is used in an automatic toll collection system for toll roads, can be equipped with an IC card, is set when entering the toll road from the entrance toll gate, and is charged via the exit toll gate A flag storage unit for storing a flag to be reset when leaving the road, an ID reading unit for reading the ID of an IC card mounted on the vehicle-mounted device, and reading by the ID reading unit when the flag is set When the power is turned on or when an IC card is newly inserted, the ID storage unit that stores the ID of the IC card that has been stored and discards the stored ID when the flag is reset, An ID comparison unit that compares the ID of the IC card read by the ID reading unit with the ID of the IC card stored in the ID storage unit, and an alarm is generated when a mismatch is detected by the ID comparison unit That comprises an alarm unit, having the basic configuration of the vehicle-mounted device of the present invention.

  By adopting the above configuration, the ID of the IC card mounted on the vehicle-mounted device when entering the toll road from the entrance toll gate is stored, and the stored ID and the power is turned on, or The ID read when the IC card is newly inserted can be compared. Further, since the alarm is generated if the IDs of the two do not match, it is possible to indicate to the user that an IC card different from the IC card when the vehicle-mounted device passes through the entrance toll gate is inserted. As a result, even when a user who owns a plurality of IC cards removes the IC card and inserts it again, it can be easily detected that the wrong IC card is inserted into the vehicle-mounted device.

  It should be noted that the insertion detection of the IC card may be performed at any time, but may be performed at predetermined time intervals, for example, at the time of standby in step S7. In this case, since the flag has already been set, the interrupt process in step S2 may be inserted before step S4 by skipping step S3. Further, the flag may indicate information indicating that the vehicle has entered the toll road, and may indicate the information indicating that when leaving, and the form of the information itself does not matter.

  As mentioned above, although this invention was demonstrated based on the suitable embodiment, the onboard equipment of this invention, its control method, and a program are not limited only to the structure of the said embodiment, From the structure of the said embodiment. Various modifications and changes are also included in the scope of the present invention.
