TECHNICAL FIELD OF THE INVENTION
The present invention relates to an automatic toll collection vehicle-mounted device that is mounted on a vehicle and automatically collects tolls by wireless communication with a toll collection roadside machine installed at a tollgate on a toll road.
[0002]
[Prior art]
A non-stop automatic toll collection system (ETC) that automatically collects tolls on toll roads is operated, and an on-board automatic toll collection device (hereinafter, referred to as an on-board ETC device) corresponding to this system has been developed. ing. In order to automatically collect tolls at a toll booth, an IC card (including a recording medium such as a memory card or an SD card) used for collecting tolls must be correctly inserted into the vehicle-mounted device. Therefore, in the ETC vehicle-mounted device, it is generally practiced to notify the user of the correct insertion of the IC card by using a display or a sound.
[0003]
Further, the currently operated ETC is protected by an advanced security system. The on-board unit is also equipped with an ETC-dedicated security module, and the on-board unit CPU can transmit and receive data to and from the IC card only through this security module, thereby preventing unauthorized use such as falsification.
[0004]
As another method of preventing unauthorized use due to tampering of the IC card, route information indicating a passage route is provided by causing the IC card to have ID information for specifying the IC card and status information for specifying the status of the IC card at that time. Is recorded in the route information, including the IC card ID information and the current IC card status information, and when the route information is read from the IC card, the ID information and the status information of the IC card are recorded. In addition, the illegal use of the IC card is detected by comparing and reading the ID information and the state information of the IC card in the path information recorded earlier and the read ID information and the state information of the IC card. There is a device (for example, see Patent Document 1).

[Problems to be solved by the invention]
However, in the above-mentioned conventional ETC on-vehicle device, the authenticity of the IC card is determined in order to prevent the unauthorized use of the IC card. However, the same applies when the authorized user mistakenly uses another IC card. It is determined to be unauthorized use, and the roadside machine is notified. In a toll road system that collects tolls according to the distance, correct toll collection cannot be realized unless the same IC card used when passing through the entrance tollgate is used when passing through the exit tollgate. If you park at a service area and get off after passing through the entrance toll booth, it is common to remove the IC card to prevent theft, and carry it with credit cards. That is. After that, when leaving the service area and heading to the exit tollgate, if you drive with an IC card different from the IC card removed at the time of getting off and enter the exit tollgate as it is, it will be installed at the exit tollgate. The predetermined communication cannot be performed with the toll collection roadside device, and the vehicle cannot pass through the exit tollgate normally.
[0007]
SUMMARY OF THE INVENTION The present invention solves such a problem, and an ETC vehicle-mounted device and a method for preventing an IC card from being erroneously inserted that can normally pass through an exit tollgate by notifying a user of erroneous insertion of an IC card. The purpose is to provide.

BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing a configuration of an on-board ETC device according to an embodiment of the present invention. In FIG. 1, an antenna 11 transmits and receives radio waves to and from a toll collection roadside device installed at a tollgate on a toll road, and a radio unit 12 transmits data to and from the roadside device through the antenna 11. Is to replace. The control unit 13 controls the entire on-board ETC device, and a microcomputer is used. The storage unit 14 includes a ROM, a RAM, a flash memory, and the like. The HMI (Human Machine Interface) unit 15 receives input of operation data from the operation unit 16, outputs a warning message or the like from the speaker 17, and displays characters and the like on the display 18. The IC card insertion unit 19 is for attaching and detaching an IC card (including a storage medium such as a memory card and an SD card). The IC card is locked when the IC card is pushed in, and the IC card is pushed again or the eject button is pushed. When pressed, the IC card is ejected. The non-volatile memory 20 is used to hold entry passage information and IC card determination information, which will be described later, even when the power of the vehicle-mounted device is turned off.
[0012]
Next, the operation in the present embodiment will be described. In FIG. 1, when the user inserts the IC card into the IC card insertion section 19 before starting the vehicle, necessary data from the IC card is stored in the storage section 14 through the IC card reader / writer. Usage statement information among the information read from the IC card is stored in the nonvolatile memory 20. When the vehicle enters the entrance tollgate, the ID number and vehicle information stored in the storage unit 14 are transmitted to the roadside unit via the wireless unit 12 and the antenna 11 according to the request data from the roadside unit, and the roadside unit enters the entrance tollgate. Since the entrance information such as the number is sent, the control unit 13 as the control means records this on the IC card by the IC card reader / writer and sets the entrance passage information in the nonvolatile memory 20. Communication with the roadside device is notified to the user via the HMI unit 15 by the speaker 17 and the display 18 as output means. When the vehicle enters the exit tollgate, in response to the request data from the roadside machine at the exit tollgate, the entrance passage information and the vehicle information stored in the IC card are transmitted from the wireless unit 12, and the roadside machine receives the data from the received data. The toll is calculated and transmitted to the on-board ETC device. The ETC on-board unit outputs the fee information to the speaker 17 and the display unit 18 and writes the information on the IC card by the IC card reader / writer. As a result, the vehicle can normally pass through the ETC gate.
[0013]
FIG. 2 is a flowchart showing the toll collection process according to the present embodiment. In FIG. 2, the on-board ETC device performs predetermined communication with a toll collection roadside device installed at a tollgate, and checks whether the vehicle has passed the entrance tollgate (step S21). If the vehicle has passed through the entrance tollgate, the entrance passage information is set in the nonvolatile memory 20 (step S22). After passing through the entrance tollgate, the vehicle travels as it is, performs predetermined communication at the exit tollgate as in the case of the entrance tollgate, and checks whether the vehicle has passed the exit tollgate (step S23). If the vehicle has passed through the exit tollgate, the entrance passage information set in the nonvolatile memory 20 is cleared. Thereby, the toll collection on the toll road that collects the toll according to the distance is completed normally.
[0014]
Next, processing when the IC card is removed after passing through the entrance tollgate and before passing through the exit tollgate will be described with reference to FIG. After passing through the entrance tollgate, park in a service area, remove the IC card from the ETC on-board unit, and turn off the power of the ETC on-board unit. The information remains recorded and held without being cleared, and the charge collection is incomplete. When the business such as the service area is completed, the vehicle-mounted ETC device is restarted and the IC card is inserted into the vehicle-mounted ETC device (step S31), and the latest usage statement information recorded on the IC card is read (step S32). ). Next, it is checked whether the IC card identification information is set in the nonvolatile memory 20 (step S33).
[0015]
The IC card identification information recorded and held in the non-volatile memory 20 is the latest usage statement information read when the IC card is inserted into the vehicle-mounted device to pass through the entrance tollgate. The usage statement information cannot be read from the IC card unless the fee is fixed after passing through the exit tollgate. Therefore, the usage statement information read after passing through the entrance tollgate, if the IC card used is the same, It is the same as the usage statement information before passing through the tollgate. Therefore, the latest usage statement information can be used as information for individually identifying IC cards.
[0016]
If the IC card discrimination information has not been set in the nonvolatile memory 20 in step S33, the read latest usage statement information is set in the nonvolatile memory 20 as IC card discrimination information. If it is after passing through the entrance tollgate, the latest usage statement information read before passing through the entrance tollgate has already been set in this IC card identification information. Processing is continued without setting usage details information. Next, it is checked whether or not the entrance passage information is set in the nonvolatile memory 20 (step S35). If the entrance passage information is set, it is determined that the vehicle has not passed through the exit tollgate, that is, the charge collection is not completed. Then, the IC card identification information set in the non-volatile memory 20 is compared and determined with the latest usage statement information read in step S32 (step S36). It is determined that the IC card used in step 1 is different from the IC card inserted later, and a warning sound indicating that the IC card is inserted incorrectly is output from the speaker 17 and / or the display 18 to notify the user. (Step S37). If the entrance passage information has not been set in step S35, it is determined that the charge collection has been completed, and the process is continued without outputting a warning sound. In step S36, if the IC card discrimination information set in the nonvolatile memory 20 is compared with the latest usage statement information read in step S32, if they match, it is determined that the IC card matches, and a warning sound is output. Continue without processing. Through these processes, it is possible to warn the user of the incorrect insertion of the IC card.
[0017]
As described above, according to the present embodiment, the entrance passage information indicating that the vehicle has passed the entrance tollgate and the IC card determination information for determining whether the IC cards before and after the entrance tollgate are the same are stored in the nonvolatile memory. When the IC card is re-inserted after stopping and restarting the vehicle-mounted device after passing through the entrance tollgate and checking the IC card identification information, it is checked whether the IC card is the same. Therefore, the user can be warned of an erroneous insertion of the IC card, and can normally pass through the exit tollgate.
[0018]
In this embodiment, the nonvolatile memory 20 is used for recording and holding the entrance passage information. However, it is needless to say that a memory backed up by a battery can be used, and similar effects can be obtained.
[0019]
