[0002]

2. Description of the Related Art In recent years, as one of the toll collection methods on toll roads, an automatic toll which completes toll collection by wireless communication between an interrogator installed on a toll gate and a transponder installed on a vehicle side. Receipt (ETC: Electronic Toll Collec
tion) system is being studied.

[0003] The automatic toll collection system is a wireless communication between a central processing unit (hereinafter referred to as a roadside unit) installed at a tollgate and an automatic toll collection unit (hereinafter referred to as an onboard unit) installed on a vehicle. This acts as a proxy for toll collection at tollgates. The roadside unit performs wireless transmission to the onboard unit, and the onboard unit transmits information on the vehicle side (vehicle type information, entrance tollgate information, check barrier information, etc.) according to the received content.
Is transmitted to the roadside device, the roadside device performs a charge calculation process in accordance with the information, transmits a result such as a charge notification to the vehicle-mounted device, and the vehicle-mounted device writes the received price information on a recording medium such as an IC card. To debit or pay later.

[0004] Automatic toll collection using an IC card is an extremely effective system because it is not necessary to stop when the vehicle is congested. If you forget to bring your IC card, you need to pay in cash. For this reason, toll booths include a booth that performs automatic toll collection and a booth that pays in cash, and the user can arbitrarily select the booth.

[0005]

However, payment at a toll booth is permitted in addition to cash payment, as well as coupon and highway card payment. Coupons and highway cards offer an advantage over discounts and are more advantageous than cash payments. Therefore, it is considered that payment is made by an IC card when the vehicle is crowded, and payment is made by a coupon or a highway card when the vehicle is not crowded. However, even if you are planning to pay by IC card because the vehicle is crowded, after the communication with the roadside machine is started near the toll booth, the congestion of the vehicle is resolved or the booth for cash payment is stopped. Since it is vacant, it may happen that you want to enter a cash-paying booth and pay by coupon or highway card.

[0006] In view of such a conventional problem, the present invention provides a method for controlling a vehicle even when the vehicle-mounted device is set in an automatic payment mode.
It is an object of the present invention to provide an on-vehicle device for road-to-vehicle communication capable of stopping automatic toll payment processing immediately before a tollgate.

The wireless circuit 2 performs wireless communication with a roadside device via an antenna. The power supply circuit 3 converts the battery voltage of the vehicle into a voltage suitable for operating each unit of the vehicle-mounted device. The non-volatile memory 4 is a memory that does not require a storage holding operation for storing an identification number unique to the vehicle on which the vehicle-mounted device is mounted and vehicle type information. RAM5
Is a memory that can be written and read at any time and temporarily stores data necessary for control and processing performed by the CPU 1. The ROM 6 is a read-only memory storing a program to be executed by the CPU 1. The operation unit 7 includes numeric keys and touch switches for giving instructions and instructions to the CPU 1. The display unit 8 includes a liquid crystal display that displays the operation state and the contents of the instruction in characters and a speaker that displays the operation state and instructions by voice. The IC card reader / writer 9 detects insertion of the IC card 10 and reads and writes data from the inserted IC card. The payment mode selection switch 11 is provided on the operation unit 7 and is a switch for the driver of the vehicle to select whether the payment mode is set to ETC or cash.

Next, the payment mode change processing in the present embodiment will be described with reference to the flowchart of FIG.
In FIG. 2, in step S1, the IC card 10
If it is detected that the card is inserted into the card reader / writer 9, it is checked in step S2 whether the ETC payment mode is selected. When the IC card is inserted, it is usually the case that the driver intends to select the ETC mode, and the driver sets the payment mode selection switch 11 to the ETC mode.
Switch to mode. In this operation, the IC card 10 may be inserted into the IC card reader / writer 9 after the payment mode selection switch 11 is switched to the ETC mode.
When the ETC payment mode is selected, in step S7,
It shifts to the ETC payment mode and enters the standby state.
When the driver changes his mind when approaching the tollgate in this state, and switches the payment mode selection switch 11 to the cash payment mode in step S3, the CPU 1 performs payment in step S4 based on the signal. Change the display of the method from ETC to cash. This display change is guided not only by the character change on the liquid crystal display but also by voice from a speaker, and the change can be easily confirmed. Next, the CPU 1 determines in step S5 that the ETC
Control to stop processing. This is, for example, the wireless circuit 2
This is done by sending an ETC cancel signal to the roadside device through Then, in step S6, the driver enters the cash payment booth and pays by cash, coupon, or highway card. If there is no change in the payment mode in step S3, the driver enters the ETC payment booth, performs the ETC processing as specified in step S8, and sets the toll from the deposit or postpaid amount described in the IC card 10. The subtracted amount is written.

As described above, according to the first embodiment,
Since the switch 11 for selecting the payment mode is provided, by selecting the cash payment mode with this switch, the automatic payment processing can be stopped even immediately before the toll booth, and the cash, coupon, highway Payment by card becomes possible.

Therefore, the same components are denoted by the same reference numerals, and the configuration is duplicated. Description is omitted.

Next, the payment mode change processing according to the second embodiment will be described with reference to the flowchart of FIG. In FIG. 4, in step S11, the IC card 10
Is detected to be inserted into the IC card reader / writer 9, in step S12, the mode automatically shifts to the ETC payment mode, and the apparatus enters the standby state. This is because, when an IC card is inserted, the driver normally intends to select the ETC mode, so that the mode automatically shifts to the ETC payment mode. Another aim is to prevent the IC card from being inserted in order to prevent forgetting to insert the IC card.
This is to prevent the transition to the TC payment mode.
After shifting to the ETC payment mode, the driver changes his / her mind, and in step S13, the cash payment mode switch 1
When 2 is pressed, the CPU 1 changes the display of the payment method from ETC to cash in step S14 based on the signal. This display change is guided not only by the character change on the liquid crystal display but also by voice from a speaker, and the change can be easily confirmed. Next, in step S15, control for stopping the ETC process by the CPU 1 is performed. This is performed, for example, by sending an ETC cancel signal to the roadside device through the wireless circuit 2. Thereafter, in step S16, the driver enters the cash payment booth and pays by cash, coupon, or highway card. If there is no change in the payment mode in step S13, the driver enters the ETC payment booth, performs the ETC processing as specified in step S17, and sets the toll from the deposit or postpaid amount described in the IC card 10. The subtracted amount is written.

As described above, according to the second embodiment,
Since the cash payment mode switch 12 is provided, the automatic payment processing can be stopped even immediately before the toll booth by selecting the cash payment mode with this switch, and the cash, coupon, and highway card can be used. Payment becomes possible.
