The source is stored, and in the case of a towing vehicle such as a trailer head, towing information, that is, a towing code is stored. The information stored in the read-only memory 5 is read by the CPU 2.

The vehicle-mounted device 1 is provided with a readable / writable memory (not shown). The readable / writable memory stores a balance amount, a payment history, and the like in a rewritable manner. The CPU 2 transmits information such as ID information and vehicle specifications from the read-only memory 5 and the readable / writable memory via the communication circuit 3 and the antenna 4 in accordance with an instruction from the roadside device 10.

The on-road unit 10 comprises an antenna 11, a communication control circuit 12, a vehicle type discriminating unit 13, a toll calculating unit 14, a vehicle axis number measuring unit 15, and the like. The above-mentioned road machine 1
In the case of No. 0, wireless communication is performed with the vehicle-mounted device 1 by the communication control circuit 12 via the antenna 11, and information such as vehicle specifications stored in the read-only memory 5 is input to the vehicle type determination unit 13. The vehicle type determining unit 13 determines whether or not the tow code is stored in the read-only memory 5, and if the tow code is not stored, performs the vehicle type determination based on the vehicle specifications and stores the tow code. Then, it is determined whether the passing vehicle is a large-sized vehicle or a medium-sized vehicle based on the number of vehicle axes measured by the vehicle axis number measuring unit 15. In this case, if the number of axes detected by the vehicle axis number measuring unit 15 is three or more, it is determined that the vehicle is a large vehicle and if the number is less than three, it is a medium-sized vehicle.

In addition, the vehicle axis number measuring unit 15 has, for example, a light transmitting unit and a light receiving unit arranged opposite to each other on both sides of a road. The light-sending unit includes a plurality of light-sending tubes arranged at regular intervals in a vertical direction, and the light-receiving unit includes a plurality of light-receiving sensors corresponding to the light-sending tubes. The number of axes of the passing vehicle is detected based on the state of light incident on the light receiving sensor by blocking the projection light from the light transmitting unit by passing the vehicle through the gap.

When the vehicle equipped with the vehicle-mounted device 1 enters the tollgate, the roadside device 10 detects the approaching vehicle, performs wireless communication with the vehicle-mounted device 1 through the communication control circuit 12 via the antenna 11, and reads out the read-only memory. The information such as vehicle specifications stored in 5 is input to the vehicle type discriminating unit 13 as shown in FIG. 2 (step A1). When the information such as the vehicle specifications is input, the vehicle type determining unit 13 determines whether or not the tow code is included (step A2). If the tow code is not included, the vehicle information further matches. It is determined whether or not to perform (step A3). As this vehicle information, for example, the license plate information of the vehicle is read and the number of axes is measured by a road machine, and it is determined whether or not the number plate information and the number of axes information included in the vehicle specifications match. . If it is determined in step A3 that the vehicle type information does not match, the collection member visually determines the vehicle type. If it is determined in step A3 that the vehicle information matches, the vehicle type is determined based on the vehicle specifications (step A4). For example, the vehicle type is specified into five categories, such as a mini car, a normal car, a medium-sized car, a large car, and an oversized car. In the case of the four-car classification, the mini-cars and the like are included in the ordinary cars and specified.

In step A2, if it is determined that the tow code is included in the readout information, it is determined whether the number of vehicle axes measured by the vehicle axis number measuring unit 15 is, for example, three or more. (Step A5), it is determined that the vehicle is a large vehicle if it has three axes or more, and a medium-sized vehicle if it is less than three axes (Step A7).

As shown in FIG. 3, when only the trailer head 21 enters the tollgate, the number of axes is "2", so that the process proceeds from step A5 to step A7 to determine that the vehicle is a medium-sized vehicle. Further, when the trailer 23 enters the toll booth as shown in FIG.
If the vehicle is towing the container 22, the number of axes is "3", and the process proceeds from step A5 to step A6, where it is determined that the vehicle is a large vehicle.

When the vehicle classification is specified by the vehicle type discriminating unit 13, the corresponding fee is calculated by the fee calculating unit 14 and transferred to the on-vehicle device 1, and the withdrawal process is performed from the balance in the readable / writable memory. In the case of the post-payment method, a process of withdrawing a charge from a pre-registered account of a predetermined financial institution is performed.

As described above, the vehicle type determining section 13 determines whether or not the tow code is stored in the read-only memory 5, and if not, performs the vehicle type determination based on the vehicle specifications. If stored, the vehicle type is determined based on the number of axes detected by the vehicle axis number measuring unit 15, so that even for a towing vehicle such as a trailer head, the presence or absence of towing can be reliably determined, and the vehicle type is determined.
