Description

The present invention relates to an automatic toll collection on-board device for an automatic toll collection (ETC (registered trademark) : Electronic Toll Collection) system that automatically collects tolls without stopping the vehicle.

  Currently, an automatic toll collection system (Electric Toll Collection System: hereinafter referred to as “ETC system”) can pay a fee even if the vehicle does not stop on a toll road. In the ETC system, an IC (Integrated Circuit) card called an ETC card is mounted, and a communication on-board device (hereinafter referred to as an ETC on-vehicle device) capable of communication and a communication antenna installed at a dedicated gate provided at the entrance / exit of a toll road DSRC (Dedicated Short Range Communication) communication is performed between the vehicle and the vehicle, information necessary for billing such as vehicle information is exchanged, and the fee is automatically settled.

In the ETC system, since the fee is settled using information such as the card ID stored in the ETC card inserted in the ETC on-board device, it is necessary that the ETC card is correctly inserted into the ETC on-board device at the toll gate on the toll road There is. Therefore, there is an automatic toll collection vehicle-mounted device that warns that the user has forgotten to install the ETC card even when the ETC card is removed in order to prevent theft in a conventional service area or parking area (for example, Patent Document 1).
Japanese Patent Laying-Open No. 2003-99831 ([0017], [0019], FIGS. 4 and 5).

Incidentally, in addition to conventional pay-per and uniform pricing pricing in Charge road, average speed, use distance, discounted in accordance with the utilization pathway has been studied. Conventionally, when using a toll road with a flat fee system in the ETC system, if an ETC card is inserted in the ETC on-board device at the entrance toll gate on the toll road, a uniform fee will be charged at the entrance toll gate. Even if the ETC card is not inserted at the exit of the road, normal charge settlement is performed. However, if a discount according to usage distance (hereinafter referred to as distance discount) is applied to a toll road with a flat fee system and the discount fee is refunded at the exit toll gate, the same ETC card at the exit of the toll road Must be plugged in.

However, in the above-mentioned automatic toll collection on-board device, it is judged that the user does not have to listen to the warning that the ETC card is installed or that the distance discount is not received, and the exit toll gate is installed without installing the ETC card. If an ETC card that is different from the ETC card that was accidentally inserted at the entrance toll gate is inserted and the exit toll gate is entered, the discount may not be applied.

As a result, the user can confirm that the distance discount is available. Note that the notification may be performed by either display or sound, or may be performed more reliably by using both.

  In S201, it is determined whether to take a break at SA or PA. Here, based on the position information detected by the position specifying unit 11 of the navigation device 1 and the map data stored in the map data storage unit 12, the navigation control unit 14 determines whether or not the vehicle has entered SA or PA. . If it is determined that the vehicle has entered the SA or PA, it is determined that the user is taking a break at the SA or PA (S201: YES), and the vehicle has just passed near the SA or PA, and is determined not to have entered the vehicle. Is determined not to take a break at SA or PA (S201: NO).

  If it is determined to take a break at SA or PA (S201: YES), the user may extract the ETC card 24 to prevent theft. For example, in S202, for example, “If an ETC card is extracted, the discount Please insert the same ETC card at the time of departure in order to receive the warning. ”The warning unit 13 warns the user to insert the ETC card 24 at the time of departure in order to receive a distance discount. The warning here may be given either by display or sound, or both. In S203, it is determined whether the parking brake operation is detected by the PKB state detection unit 16 connected to the navigation control unit 14, or the ACC state detection unit 15 detects that ACC is OFF. When it is determined that the operation of the parking brake or ACC OFF is not detected (S203: NO), it can be determined that the vehicle has not stopped yet, so the determination of S203 is repeated. When it is determined that the parking brake is activated or the ACC is turned off (S205: YES), it can be determined that the vehicle has stopped. Therefore, if the ETC card 24 is not removed, theft is prevented in S204. The notifying unit 13 warns to remove the ETC card 24.

  In S205, it is determined whether the PKB state detection unit 16 connected to the navigation control unit 14 has released the parking brake or the ACC state detection unit 15 has detected ACC ON. If the release of the parking brake or the ON of the ACC is not detected (S205: NO), it can be determined that the vehicle is still stopped, so the determination in S205 is repeated. If it is determined that the parking brake is released or ACC is turned on (S205: YES), since it can be determined that the vehicle starts to travel, it is determined in S206 whether or not the ETC card 24 is inserted. Here, whether or not the ETC card 24 is inserted is determined by an insertion / extraction detection circuit (not shown) provided in the ETC card interface unit 23.

  When it is determined that the ETC card 24 is not inserted (S206: NO), the notification unit 13 notifies the user that the ETC card 24 is inserted, such as “Please insert the same ETC card” in S207. When it is determined that the ETC card 24 is inserted (S206: YES), the process proceeds to S300 in FIG.

  On the other hand, if it is determined in S201 that there is no break in SA and PA (S201: NO), it is determined in S208 whether or not the ETC card 24 has been removed. The determination here detects a case where the driver or a passenger removes the ETC card 24 while traveling. Whether or not the ETC card 24 has been removed is determined by an insertion / removal detection circuit (not shown) provided in the ETC card interface unit 23 as in the determination in S206. When it is determined that the ETC card 24 has been extracted (S208: YES), for example, in S209, the notification unit 13 receives a distance discount, such as “Please insert the same ETC card to receive a discount”. A warning is given to insert the ETC card 24. On the other hand, if it is determined that the ETC card 24 has not been removed (S208: NO), the process proceeds to S300 in FIG.

  In FIG. 3, in S300 (processing corresponding to the exit determination means in the present invention), it is determined whether or not the vehicle has approached the vicinity of the exit toll gate on the toll road. Whether the vehicle has approached the vicinity of the exit toll booth is based on whether the ETC on-board unit 2 has started communication with the notice antenna of the exit toll booth installed on the road near the exit toll booth or the navigation device 1 Based on the position information detected by the position specifying unit 11 and the map data stored in the map data storage unit 12, it is determined whether or not the vehicle has approached the vicinity of the exit toll gate. When it is determined that the vehicle is not approaching the vicinity of the exit toll gate (S300: NO), the process proceeds to S201 in FIG. 2 and the above-described processing is repeated.

  On the other hand, if it is determined that the vehicle has approached the vicinity of the exit toll gate (S300: YES), whether or not the ETC card 24 is inserted is determined in S301 as in S206 of FIG. When it is determined that the ETC card 24 is inserted (S301: YES), the process proceeds to S303, and when it is determined that the ETC card 24 is not inserted (S301: NO), in S302, “The same ETC card is inserted. Etc. ”is notified by the notification unit 13. In S303, it is determined again whether or not the ETC card 24 is inserted, and a final confirmation for using the ETC card 24 at the exit toll gate is performed.

  If it is determined that the ETC card 24 is not inserted (S303: NO), a refund due to a distance discount such as "Discount service was not received" when passing through the exit toll booth in S308 Is notified (unprocessed notification). On the other hand, when it is determined that the ETC card 24 is inserted (S303: YES), it is determined whether or not the ETC card 24 inserted in S304 is the same as the ETC card 24 used at the entrance toll gate. Here, whether or not the ETC card 24 is used at the entrance toll booth is determined by the card ID of the ETC card 24 stored in the RAM of the ETC control unit 22 when passing through the entrance toll booth and the ETC card 24 inserted. This is done by comparing the card IDs. If the card ID stored in the RAM of the ETC controller 22 matches the card ID of the inserted ETC card 24, the inserted ETC card 24 is the same as the ETC card 24 used at the entrance toll gate. If they do not match, it is determined that the inserted ETC card 24 is not the ETC card 24 used at the entrance toll gate. If it is determined that the inserted ETC card 24 is the same as the ETC card 24 used at the entrance toll gate (S304: YES), a normal discount refund process is performed (S305).

  In the normal discount refund process in S305, first, the entrance toll gate information stored in the memory 25 of the ETC card 24 is transmitted to the communication antenna installed at the exit toll gate of the ETC system via the communication control unit 21, The discount amount calculated based on the entrance toll gate information at the exit toll gate is received by the ETC on-board unit 2. Then, a process of refunding the discount amount to the inserted ETC card 24 is performed.

When it is determined that the inserted ETC card 24 is not the same as the ETC card 24 used at the entrance toll gate (S304: NO), the process proceeds to S306. In S306, it is determined whether or not the fee can be settled corresponding to the ETC card 24 inserted at the exit toll gate that is approaching. This determination is made based on information received by the ETC vehicle-mounted device 2 from the notice antenna when the vehicle approaches the vicinity of the exit toll gate. If it is determined that the ETC system at the exit toll booth is not compatible with the ETC card 24 in which it is inserted (S306: NO), the process proceeds to S308, and “No discount service was received when passing through the toll booth. ”Or the like to notify that a refund due to a distance discount is not received (unprocessed notification). On the other hand, when it is determined that the processing of the ETC card 24 in which the ETC system at the exit toll gate is inserted (S306: YES), another card processing of S307 is performed.

  In the separate card processing of S307, since the inserted ETC card 24 is an ETC card 24 different from the ETC card 24 used at the entrance toll gate, the entrance toll gate stored in the RAM of the ETC control unit 22 The information is transmitted to the communication antenna installed at the exit toll booth of the ETC system via the communication control unit 21, and the discount amount calculated based on the entrance toll booth information is received by the ETC on-board unit 2 at the exit toll booth. The Then, a process of refunding the discount amount to the inserted ETC card 24 is performed.

  The processing method for refunding the discount amount by the distance discount in S305 and S307 differs depending on whether the inserted ETC card 24 is a prepaid card or a credit card. When the inserted ETC card 24 is a prepaid card, by adding the discount amount received by the ETC in-vehicle device 2 to the balance information of the prepaid card stored in the memory 25 of the ETC card 24, and rewriting the balance information, Refund the discount amount.

  On the other hand, when the inserted ETC card 24 is a credit card, it is possible to transfer the discount amount to the designated account registered in the ETC card 24, but the transfer fee is added to the refund of a small amount. , The burden on the operator will increase. Therefore, a prepaid amount (addition amount of discount amount) area (corresponding to a storage area in the present invention) is secured in the memory 25 of the ETC card 24, and the discount amount is stored in the prepaid amount area. Then, when the ETC system is used next time, the amount stored in the prepaid amount area is used preferentially, and the difference from the required fee is settled by credit. In the case of a prepaid card, a prepaid amount area may be secured separately from the balance information of the prepaid card, and a discount amount may be added to increase the amount.

  As described above, according to the ETC vehicle-mounted device 2 of the present embodiment, the ETC card 24 that has been inserted at the entrance toll gate is inserted on the toll road of the flat fee system that is connected to the navigation device 1 and to which the distance discount is applied. Even if an ETC card 24 that is different from the ETC card 24 inserted at the entrance toll gate is inserted, the discount fee can be refunded smoothly or passed through the exit toll gate. . Therefore, it is possible to prevent different cards from being inserted at the entrance toll gate and the exit toll gate, and to settle when a different card is inserted.

  In the present embodiment, the ETC vehicle-mounted device 2 connected to the navigation device 1 has been described as an example. However, the ETC vehicle-mounted device 2 may not be connected to the navigation device 1. In that case, the ETC vehicle-mounted device 2 has the same configuration as the ACC state detection unit 15, the PKB state detection unit 16, and the notification unit 13, and SA, PA based on the detection signal of the ACC state detection unit 15 or the PKB state detection unit 16. Stops and outgoing calls are detected, approach to the vicinity of the exit toll gate is detected by signal reception from the notice antenna by the communication control unit 21, and various notifications and warnings are performed by notification means provided in the ETC on-vehicle device 2. As a result, it is possible to smoothly refund the discounted amount of charges and to pass through the exit toll gate.
