Abstract

PROBLEM TO BE SOLVED: To improve the convenience of a toll road etc., by automatically displaying a traffic charge at the point of a present traveling time at an exit etc., of the toll road etc. SOLUTION: When a vehicle mounting an IC card 11 passes through the entrance (a point A) of the toll road and arrives at its exit (a point B), the traffic charge is calculated through the radio transmission and reception of data between with automatic charging devices 12a and 12b. A processor 13 executes subtracting processing from a traffic charge stored in the IC card 11 by radio transmission and reception through the automatic charging device 12. In this case, from the traveling position (two-dimensional latitude and longitude) of its own vehicle measured by a GPS receiver 18, the traffic charge of the toll road at each exit of the toll road in a picture-displayed map is outputted to LCD 21a to display at the lower part of its picture.

In FIG. 2, this automatic billing system is mounted on a vehicle to wirelessly transmit and receive information about traveling on a toll road, and, for example, I that stores a toll in advance.
It has a C card 1 (prepaid card). Further, the automatic charging device 2a is installed at an entrance (point A) of a toll road or the like and wirelessly transmits / receives information regarding traveling to / from the IC card 1, and is installed at an exit (point B) of a toll road or the like, the IC card 1 and an automatic billing device 2b that transmits and receives information regarding traveling to and from the vehicle. Further, it has a processing device 3 which is connected to the automatic billing devices 2a and 2b by a communication line to exchange information regarding the traveling of a vehicle equipped with the IC card 1 on a toll road to process (billing) a traveling toll. ing.

The operation of this conventional example will be described below. A vehicle equipped with the IC card 1 approaches and passes an entrance (point A) such as a toll road. At this time, the automatic billing device 2a transmits an information reading radio wave to the IC card 1,
The C card 1 transmits self-information, for example, self-identification code information, passing point (entrance or exit) information such as toll roads, and remaining toll information to the automatic billing device 2a. The self-identification code of the vehicle equipped with the IC card 1, the entrance (point A) information such as a toll road, and the remaining toll information received by the automatic billing device 2a are transmitted to the processing device 3 through the communication line. . After that, when the vehicle equipped with the IC card 1 travels on the toll road and approaches the exit (point B), the automatic billing device 2b which detects this approach transmits a radio wave for reading information to the IC card 1, and the IC card 1 1 transmits identification code information and toll road entrance (point A) information to the automatic charging device 2b.

The vehicle identification code information and the exit (point B) information received by the automatic charging device 2b are transmitted to the processing device 3 through a communication line. In the processing device 3, the vehicle (self-identification code) information equipped with the IC card 1 transmitted from the automatic charging device 2a, the entrance (point A) information of the toll road, etc. and the remaining toll information, and the automatic charging device 2b. Compared with the vehicle identification code information and exit (point B) information transmitted from
Calculate tolls. When the IC card 1 stores (prepaid) the toll in advance, a process of subtracting from the remaining toll is performed.

As described above, the above-described conventional automatic billing display system can automatically bill the toll on a toll road or the like.

[0006]

However, in the above-described automatic billing display system of the conventional example, the toll is not known unless the vehicle passes the point B at the exit of the toll road or the like, which is inconvenient. That is, there is a drawback that the toll up to the current time of travel is not known while the vehicle is traveling on the toll road.

The present invention solves the problems in the prior art as described above, and can automatically display the current traveling point on a toll road, for example, a toll for each passage through an exit, and to use the toll. To provide an excellent automatic billing display system with improved convenience.

[0008]

In order to achieve the above object, the automatic billing display system of the present invention measures the present time of a traveling route such as a toll road and automatically calculates the toll at the present moment during traveling. Is displayed. As a result, the toll is known in advance and the convenience of its use is improved.
