As shown in FIG. 11, when the vehicle A detects that the vehicle-mounted device 30 has entered the communication area in step 600, the detection time as the time when the vehicle 30 enters the communication area is recorded in step 602.

Similarly, in vehicle B, when it is detected that vehicle-mounted device 30 has entered the communication area in step 604, the detection time as the time when the vehicle 30 enters the communication area is recorded.

As a method for the in-vehicle device 30 to detect that the vehicles A and B have entered the communication area, for example, it is detected whether or not the signals from the tollgate antennas 342, 344, and 346 are received.

On the other hand, in the roadside machine, the inquiry signal is transmitted from the tollgate antenna 341 in step 608.

In the vehicle A, the in-vehicle device 30 executes the step 610.
When the inquiry signal is received at, the recording time is read at step 612, and the ID of the vehicle A and the recording time are transmitted to the tollgate antenna 341 at step 614.

Similarly, in vehicle B, when the in-vehicle device 30 receives the inquiry signal in step 616, step 61
The recorded time is read out in step 8, and the ID of vehicle B is read in step 620.
And the recording time are transmitted to the tollgate antenna 341.

On the other hand, when the roadside machine receives the ID and the recording time from the vehicles A and B by the tollgate antenna 341 in step 622, the recording time of the vehicle A and the recording time of the vehicle B are compared in step 624. At this time, the recording time of the vehicle A that has entered the communication area earlier is earlier than the recording time of the vehicle B. Therefore, in step 626, the vehicle having the earlier recording time is specified as the vehicle A and the recording time is later. One vehicle is identified as vehicle B.

The following processing is the same as in the first embodiment,
The same reference numerals are given to the steps and the description thereof will be omitted.

Therefore, in the third embodiment, even if there are a plurality of vehicles within the communicable area, all the vehicles can be surely identified, and the pinpoint antenna is not used, so that the structure is simplified.

Incidentally, instead of the detection time of the second embodiment,
Record the information indicating the order of entry into the communication area on the road machine,
Each vehicle may be specified based on this.

In addition, specifying the communication vehicle by the communication vehicle specifying device of the present invention is extremely effective in connection with the illegal traffic image capturing system for photographing the vehicle such as communication failure or insufficient charge.

[0094]

According to the communication vehicle identification device of the present invention as set forth in claim 1, an in-vehicle device for judging entry into a toll collection area, storing order information, and transmitting the stored order information to a roadside antenna, Even if there are multiple vehicles in the communicable area, it is configured to include a roadside device that identifies a communication vehicle based on the order information transmitted from the vehicle-mounted device and performs transmission for fee collection. It has an excellent effect that all vehicles can be surely specified.

In the communication vehicle specifying device according to the present invention as set forth in claim 2, in the invention as set forth in claim 1, the order information is the time when the charge collection area is entered, the time elapsed from the entry, and the order of entry. Therefore, even if there are a plurality of vehicles in the communicable area, all the vehicles can be reliably identified, which is an excellent effect.

In the communication vehicle identification device according to the present invention as defined in claim 3, the on-vehicle device determines the entry into the toll collection area by receiving the radio wave from the pinpoint antenna arranged on the road. In addition to the effect, it has an excellent effect that it is possible to judge the entry into the toll collection area in advance and to give a sufficient preparation time for the toll collection communication.

In the communication vehicle specifying device according to the present invention of claim 4, in addition to the effect of claim 3, the radio wave from the pinpoint antenna includes time information and the time information is stored in the vehicle-mounted device. The excellent effect that the reference time does not vary among the vehicles and the vehicle can be accurately identified.

According to the communication vehicle identifying apparatus of the present invention as defined in claim 5, the communication vehicles are identified by the on-road equipment in the invention as defined in claim 1 in order from the earliest transmitted time. Even if a plurality of vehicles exist in the area, all the vehicles can be surely specified, which is an excellent effect.

In the communication vehicle specifying device according to the present invention as defined in claim 6, the communication vehicles are identified by the roadside equipment in the invention as defined in claim 2 in order from the one with the shortest transmitted time. Even if there are a plurality of vehicles in the feasible region, it is possible to reliably identify all the vehicles.

The communication vehicle specifying device according to the present invention of claim 7 is a pinpoint for receiving an ID from a vehicle arranged on the road and entering a toll collection area and transmitting the ID to the toll antenna on the toll collection road. Since all the vehicles are secured even if there are multiple vehicles within the communicable area, the antenna and the roadside device that identifies the communication vehicle based on the ID and performs transmission for fee collection are adopted. Can be specified as
Since the ID originally owned by the vehicle can be used, there is an excellent effect that it is not necessary to generate special information for identifying the vehicle.
