[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a toll collection system for charging a passing vehicle by exchanging information with the passing vehicle by wireless communication.

[0002]

2. Description of the Related Art As a toll collection system of this type, a non-stop automatic toll collection system (ETC system) which has been proposed in the past, requires an antenna provided at a tollgate and an on-board unit mounted on a vehicle. Then, information for toll collection is exchanged by two-way communication in the designated communication area. This communication area is provided for each lane in which a vehicle-equipped vehicle (ETC vehicle) passes in a tollgate, and a lane separation band is provided on both sides of each lane so that one vehicle can pass each vehicle. Are configured. When setting up a gate, it is necessary to take the form of an interchange, which limits the places where it can be implemented,
Expenses such as installation, maintenance, and management are required. further,
The provision of the gate makes it impossible for a passing vehicle to run through at high speed, which may cause traffic congestion depending on the implementation environment. In order to solve such a problem, a system has been proposed which performs automatic toll collection in a free lane system in which a plurality of lanes in a tollgate can be moved left and right freely without a gate.

[0003] With respect to the usage status of such a system, see, for example, Japanese Patent Laid-Open Publication No.
1) It is described in "Automatic charging system" and the like.

A second unbilled vehicle photographing camera for photographing the vehicles passing the second lane that is not charged is detected by the confirmation roadside wireless device.

Next, the operation will be described. The first billing roadside device 6a installed in the first gantry 4 communicates with the first vehicle-mounted device 3a mounted on the first ETC vehicle 2a passing through the first gantry. Transfer of toll information is performed within the communication area provided by the roadside wireless device 6a, and toll billing processing is performed based on the transferred information. First
The vehicle detection means 7a of the first gantry 4
It detects that the C vehicle 2a has passed. The first billing confirmation roadside wireless device 8a installed in the second gantry 5 is configured such that the first ETC vehicle 2a whose passage has been confirmed by the first vehicle detecting means 7a is connected to the first billing roadside wireless device. Machine 6a
Confirm that you have been charged by. The first non-billed vehicle photographing camera 9a captures a license plate of a vehicle (non-billed vehicle) whose passing has been confirmed by the first vehicle detecting means 7a but has not been confirmed to have been charged. Later, based on the information on the license plate, the user (for an uncharged vehicle) is billed for payment and the fee is settled. Regarding the second charging roadside radio 6b, the second vehicle detecting means 7b, the second charging confirmation roadside radio 8b, and the second non-charging vehicle photographing camera 9b, the second ETC vehicle 2
b and the second vehicle-mounted device 3b mounted on the second ETC vehicle 2b with respect to the first charging roadside radio 6a,
Vehicle detection means 7a, first billing confirmation roadside radio 8a,
Further, the same operation as the operation of the first uncharged vehicle photographing camera 9a with respect to the first ETC vehicle 2a and the first vehicle-mounted device 3a mounted on the first ETC vehicle 2a is performed.

[0006]

In the non-stop automatic toll collection system of the free lane system as described above, the transmission wave from the charging roadside radio corresponding to the adjacent lane is changed to the charging roadside corresponding to the own lane. Leakage may occur near the communication area of the wireless device. If the electric field strength level of the transmitted wave in the leaked portion is higher than the minimum reception sensitivity level of the vehicle-mounted device, the vehicle-mounted device passing through the own lane temporarily reacts to the transmission wave from the adjacent lane, A failure may occur in communication between the on-vehicle device and the charging roadside device corresponding to the own lane and in charging processing. For example, as shown in FIG.
0 (non-ETC vehicle) runs on the second lane 1b
The first lane 1a on which the non-ETC vehicle 10 travels when traveling in the first lane 1a in the direction A in parallel with the vehicle 2b.
The first charging roadside radio 6a (and the first charging confirmation roadside radio 8a) establishes communication 11 of charging information (and charging confirmation information) with the ETC vehicle 2b running on the second lane 1b. Therefore, it is determined that the non-ETC vehicle 10 has been charged, and the vehicle passes through the non-ETC vehicle 10 without being charged. There is a problem that communication with the vehicle 2b is hindered and normal billing processing is not performed.

SUMMARY OF THE INVENTION The present invention has been made to solve such a problem, and has a non-ET driving in a free lane.
The purpose is to prevent vehicle C from passing without being charged.
