Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention receives identification information transmitted from an in-vehicle device mounted on a vehicle passing through an exit gate of a toll road, and calculates a toll of the vehicle,
The present invention relates to a toll road toll collection method for deducting a toll from a prepaid card (hereinafter referred to as a "prepaid card") attached to the onboard device through communication with the onboard device.

[0002]

2. Description of the Related Art A non-stop toll collection system has been proposed which collects tolls without stopping the vehicle by wirelessly communicating between the toll booth and the vehicle when passing through a toll road. (See Kaihei 1-259484). With this system, when a vehicle enters the entrance of a toll road, an in-vehicle response device (hereinafter abbreviated as "in-vehicle device")
Transmits the identification information of the vehicle and the credit number of the user, and when the road side receives the identification information, the identification information of the entrance is transmitted to the vehicle-mounted device. At the toll road exit toll gate, when the entrance identification information is received from the vehicle-mounted device, the toll is calculated and charged to the account of the vehicle owner or the like.
Since this system does not stop the vehicle at the tollgate, it has an advantage that traffic congestion at the tollgate on the toll road can be eliminated.

By the way, the system is modified so that a prepaid card is combined with an in-vehicle device, and when a vehicle passes through an exit toll gate on a toll road, the amount corresponding to the charge is automatically withdrawn from the prepaid card. It is also possible.

[0004]

When automatically deducting the amount of money from a prepaid card at the exit of a toll road, the amount cannot be automatically deducted if the balance of the card is insufficient. Must be stopped and cash must be delivered. Therefore, there is a problem that the flow of vehicles stops at the exit of the toll gate, and the advantage of the non-stop toll collection system that eliminates traffic congestion at the entrances and exits of toll roads cannot be utilized.

Also, if the vehicle breaks through the exit, the license plate must be photographed by the camera and billed at a later date. Therefore, the present invention provides a toll road charge collecting method that allows a vehicle to pass nonstop without stopping the vehicle at the exit of the toll road even when it is necessary to stop the vehicle and settle the toll. Aim to achieve.

[0006]

One of the features of the toll road toll collection method of the present invention is that a prepaid card provided with an area for writing user identification information is used.
If the identification information including the user identification information transmitted from the in-vehicle device equipped with this type of card is received, the card balance becomes negative when the amount equivalent to the toll is automatically deducted from the card. If it is determined to be negative, it stores the user identification information and
Information that the balance is negative is transmitted to the vehicle-mounted device of the vehicle to allow the vehicle to pass nonstop.

Therefore, at the exit of the toll road, the vehicle can be passed nonstop without stopping the vehicle. Charges can be individually billed at a later date based on the stored user identification information. When selling the "prepaid card provided with an area for writing user identification information", when the purchaser presents an identification card, the purchaser's name, address, and other information for identifying the purchaser are recorded on the card. It is preferable to write in. This is because when the user passes the vehicle due to insufficient balance, he / she will ask the user to increase the balance at a later date, and if there is no increase even after a certain period of time, the charge will be reminded.

The entrance information is information for identifying the entrance gate where the vehicle has entered the toll road, and this entrance information is the same system as that shown in FIG. There is no collection place 1i, and instead there is a toll ticket issuing place.) Is the information transmitted to the vehicle-mounted device.
However, entrance information is not required if it is a toll road with a uniform fare.

The on-road unit 1g receives the identification information transmitted from the on-vehicle unit, and stores the information in the memory 1 built in the information processing unit 1g _2.
Store in g ₃ . Then, the balance of the card is checked to determine whether or not the amount of money required to pass the exit remains (step S8). If it remains, it is judged to be normal (step S10) and the new balance is written in the card 3 (step S11).

When the vehicle leaves the first zone Z ₁ , thereafter, an instruction to "pass through" is displayed on the guide display plate 1h (FIG. 5; step S15). This display is continued until it is confirmed that the display end sensor 1f has detected the vehicle (step S16). After that, the vehicle is in the second zone Z

On the other hand, if the balance is judged in step S9 and there is no balance (step S12), the fact that the balance is insufficient is written in the in-vehicle device through the first antenna 1c (step S13), and the vehicle is in the first zone Z ₁ Wait until you move out of the zone _{1 and} when the vehicle moves out of the first zone Z ₁ , "Please pass through to the information display board 1h. However, please pay the deficit within a few days because the balance of the card is insufficient. Is displayed (FIG. 5; step S21). This display continues until the display end sensor 1f confirms that the vehicle is detected (step S22). From this display, the driver knows that he / she can pass through the exit, but the balance of the card is insufficient, and the account needs to be paid at a later date. Vehicle is second
When entering the zone Z ₂ (step S23), the vehicle is passed without erasing the identification information (step S24). The liquidity display section 2d of the vehicle-mounted device 2 displays for a while the fact that the payment is required later.

As shown in the above processing procedure, stopping the vehicle at the exit of the toll road means that the card is not inserted or communication is not established between the road and vehicle, and the toll collection point 1i collects the toll. Only when the procedure (step S6) is performed, in all other cases, the vehicle can be passed nonstop. Then, it is conceivable that the driver, who has learned that the balance of the card is insufficient and that the fee needs to be settled at a later date, takes an action to settle at a predetermined institution. For example, when buying a new card at a store,
Ask the card to reduce the balance.
