Abstract

The present disclosure provides an inter-vehicle communication system configured to detect a vehicle as a communication target of DSRC to properly establish an automatic driving system. In the inter-vehicle communication system configured to perform communication between a plurality of vehicles using DSRC, each of vehicles includes an identification code (ID) of the vehicle in information to be transmitted by a DSRC unit. Each vehicle includes: an individual communication unit (optical communication unit) for optical communication, which is configured to transmit/receive IDs of vehicles through communication between individual vehicles; and a unit configured to detect information having a corresponding ID by collating the ID received by the individual communication unit with the ID included in the information received by the DSRC unit. Through ID collation, a communication counterpart vehicle of DSRC is detected.

Claims

1. An inter-vehicle communication system configured to perform communication between a plurality of vehicles using dedicated short range communication (DSRC),

wherein each of the vehicles includes:

an individual communication unit configured to transmit information by DSRC after incorporating an identification code of the vehicle in the information and transmit/receive identification codes of the vehicles by performing communication between the vehicles, respectively; and

an information detecting unit configured to detect information required for an own-vehicle based on an identification code included in information received by the DSRC.

2. The inter-vehicle communication system of claim 1, wherein each of the vehicles transmits a signal including an identification code of the own-vehicle, and

the information detecting unit collates the identification code received by the individual communication unit with the identification code included in the information received by the DSRC to detect information having a corresponding identification code.

3. The inter-vehicle communication system of claim 1, wherein each of the vehicles transmits a signal including an identification code of a communication counterpart vehicle, and

the information detecting unit collates an identification code of an own-vehicle with the identification code included in the information received by the DSRC to detect information having a corresponding identification code.

4. The inter-vehicle communication system of claim 2, wherein each of the vehicles transmits a signal including an identification code of a communication counterpart vehicle, and

the information detecting unit collates an identification code of an own-vehicle with the identification code included in the information received by the DSRC to detect information having a corresponding identification code.

5. The inter-vehicle communication system of claim 1, wherein the individual communication unit is an optical communication unit configured to transmit/receive an identification code between one vehicle and another vehicle to which an optical signal is projected from the one vehicle.

6. The inter-vehicle communication system of claim 2, wherein the individual communication unit is an optical communication unit configured to transmit/receive an identification code between one vehicle and another vehicle to which an optical signal is projected from the one vehicle.

7. The inter-vehicle communication system of claim 3, wherein the individual communication unit is an optical communication unit configured to transmit/receive an identification code between one vehicle and another vehicle to which an optical signal is projected from the one vehicle.

8. The inter-vehicle communication system of claim 4, wherein the individual communication unit is an optical communication unit configured to transmit/receive an identification code between one vehicle and another vehicle to which an optical signal is projected from the one vehicle.

9. The inter-vehicle communication system of claim 5, wherein at least an optical transmitting unit and an optical receiving unit of the individual communication unit are integrally embedded in a lamp of an automobile.

10. The inter-vehicle communication system of claim 6, wherein at least an optical transmitting unit and an optical receiving unit of the individual communication unit are integrally embedded in a lamp of an automobile.

11. The inter-vehicle communication system of claim 7, wherein at least an optical transmitting unit and an optical receiving unit of the individual communication unit are integrally embedded in a lamp of an automobile.

12. The inter-vehicle communication system of claim 8, wherein at least an optical transmitting unit and an optical receiving unit of the individual communication unit are integrally embedded in a lamp of an automobile.

13. The inter-vehicle communication system of claim 1, wherein the information transmitted by the DSRC includes at least travel information of the own-vehicle and road information.

14. The inter-vehicle communication system of claim 1, wherein the inter-vehicle communication system is employed in a vehicle provided with an automatic driving system configured to perform an automatic driving control with reference to the information received by the DSRC.
