Abstract

An on-vehicle terminal apparatus for a DSRC system includes a mobile station (1) mounted on a car, a radio tag (2) mounted on the car separately from the mobile station (1), and a first communication means (11) provided for communication with the mobile station (1) and a base station (3) installed on a road. Information transmitted to the base (3) from the mobile (1) contains car information which serves to determine operation of application for which the DSRC system is employed. Tag information recorded in the tag (2) contains the car information. The mobile station (1) includes a second communication means (12) for communication with the tag (2). The car information transmitted to the base station (3) is acquired from the radio tag (2) through the second communication means (12). Handleability and serviceability of the on-vehicle terminal apparatus is remarkably enhanced.

Claims

1. An on-vehicle terminal apparatus for a dedicated short range communication system, comprising:

a mobile station mounted on a motor vehicle;

a radio tag mounted on said motor vehicle separately from said mobile station; and

first communication means provided in association with said mobile station for performing communication not only with said mobile station but also with a base station installed in association with a road,

wherein information transmitted to said base station from said mobile station contains motor vehicle information which serves for determining operation of application for which said dedicated short range communication system is employed,

wherein tag information recorded in said radio tag contains said motor vehicle information,

wherein said mobile station includes second communication means for performing communication with said radio tag, and

wherein said motor vehicle information transmitted to said base station is acquired from said radio tag through the medium of said second communication means.

2. An on-vehicle terminal apparatus for a dedicated short range communication system according to claim 1,

wherein said radio tag includes function destroying means for disabling permanently intrinsic function as said radio tag.

3. An on-vehicle terminal apparatus for a dedicated short range communication system according to claim 1,

wherein said motor vehicle information recorded in said radio tag contains vehicle type information concerning classification of the motor vehicle types on a per toll road basis.

4. An on-vehicle terminal apparatus for a dedicated short range communication system according to claim 1,

said mobile station including:

a temporary recording area;

information reading means for reading out said tag information recorded in said radio tag; and

information recording means for recording the tag information read out by said information reading means in said temporary recording area,

wherein said first communication means is designed to transmit the information recorded in said temporary recording area to said base station.

5. An on-vehicle terminal apparatus for a dedicated short range communication system according to claim 4,

wherein said mobile station is so arranged that upon power-on of said mobile station, said tag information is read out from said radio tag to be recorded in said temporary recording area.

6. An on-vehicle terminal apparatus for a dedicated short range communication system according to claim 4,

wherein said mobile station is so arranged that after completion of the dedicated short range communication, said tag information is read out from said radio tag to be recorded in said temporary recording area for updating the information recorded in said temporary recording area.

7. An on-vehicle terminal apparatus for a dedicated short range communication system according to claim 6,

wherein said mobile station is so arranged that after lapse of a predetermined time since completion of end processing of the dedicated short range communication, said tag information is read out from said radio tag to be recorded in said temporary recording area for updating the information recorded in said temporary recording area.

8. An on-vehicle terminal apparatus for a dedicated short range communication system according to claim 4,

wherein said mobile station is so arranged that after the processing for reading out said tag information has ended successfully, said tag information is read out from said radio tag by a first predetermined number of times at a predetermined period to be recorded in said temporary recording area.

9. An on-vehicle terminal apparatus for a dedicated short range communication system according to claim 4,

wherein said mobile station is arranged such that the tag information is read out from said radio tag at a predetermined period to be recorded in said temporary recording area and that when processing for reading out said tag information has failed at least a second predetermined number of times, the information recorded in said temporary recording area is discarded.
