Description

  The present invention relates to an on-board device for automatic toll collection in an ETC (Electronic Toll Collection) system that completes toll collection on a toll road such as an expressway through wireless communication between a roadside device and the on-vehicle device.

  In a conventional automatic toll collection in-vehicle device (hereinafter referred to as an ETC in-vehicle device), an IC card (hereinafter referred to as an ETC card) used by a user for automatic fee collection is inserted into a card socket of the ETC in-vehicle device and a password is entered. Is entered, the ETC in-vehicle device collates the entered personal identification number with the stored personal identification number, and if it matches, the ETC system determines that it is used by a legitimate user and permits the use of the ETC system. It has become. Such an ETC card authentication method has a problem that it is difficult to prevent unauthorized use because it is not convenient because it requires the input of a password every time it is used, and the password is simple. . For this reason, a technique has been proposed that is highly convenient and prevents unauthorized use by a third party of an ETC card with a high probability (see, for example, Patent Document 1).

  The technology for preventing unauthorized use of the card in the above prior art creates third identification information for identifying the legitimacy from the serial number of the ETC in-vehicle device and the serial number of the card used in the ETC in-vehicle device. Is recorded on the ETC card. Therefore, even if a third party tries to use the lost or stolen ETC card in the ETC in-vehicle device of his / her vehicle, the third identification information is read from the ETC card, and therefore the third identification is performed in the ETC in-vehicle device. The meaning of the information is unknown, and as a result, the ETC system cannot be used.

  On the other hand, the conventional ETC in-vehicle device is configured so that the ETC function becomes effective when an IC card is inserted, so if you forget to insert the IC card and try to pass the ETC toll gate, the gate will not open, and the ETC system Cannot be used. Further, if the user forgets to remove the IC card and leaves it in the vehicle, the IC card may be stolen and the IC card may be illegally used. Therefore, an ETC in-vehicle device has been proposed in which an in-vehicle device is fixed to a vehicle and a portable unit carried by a passenger, and an IC card is inserted into the portable unit (for example, see Patent Document 2).

  As shown in FIG. 14, the separation type ETC in-vehicle device includes an ETC antenna 31 for transmitting and receiving radio waves to and from a roadside device, and an ETC control unit for controlling the ETC in-vehicle device. 32, a short-range wireless communication unit 33 for performing communication with the portable unit 4, and a short-range wireless communication antenna 34.

The wireless communication unit 42 includes a short-range wireless communication unit 42 for communicating with the reader 43, the vehicle installation unit 3, and a short-range wireless communication antenna 41.

  FIG. 15 is a flowchart showing an operation from reading ETC card information such as personal information and usage information recorded on an IC card to enabling the ETC function in the ETC in-vehicle apparatus configured as described above. . 14 and 15, when the vehicle installation unit 3 is powered on, the ETC control unit 32 requests ETC card information from the portable unit 4 through the short-range wireless communication unit 33 and the short-range wireless communication antenna 34 ( S501). When the portable unit 4 receives the ETC card information request at the short-range wireless communication unit 42, the IC card reader 43 reads the ETC card information recorded on the IC card 44, and the vehicle installation unit 3 through the short-range wireless communication antenna 41. Send to. The vehicle installation unit 3 waits until ETC card information is sent from the portable unit 4 (S502). When the ETC card information is received, the function of the ETC in-vehicle device is validated (S503). When the function of the ETC in-vehicle device is validated, the ETC control unit 32 communicates with the roadside device at the toll booth and processes the toll road usage fee payment.

As described above, even in the conventional ETC in-vehicle device, the IC card is inserted into the portable unit carried by the passenger in response to a request from the vehicle installation unit without inserting the IC card into the vehicle installation unit fixed to the vehicle. In this way, it is possible to prevent forgetting to insert and forgetting the IC card.
