Inter-vehicle communication system

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

• a DSRC communication unit configured to transmit vehicle information associated with an identification code of an own-vehicle and receive vehicle information associated with an identification code of another vehicle through the DSRC;
• an optical communication unit including an optical transmitting unit and an optical receiving unit each configured to transmit the identification code of the own-vehicle and receive the identification code of the another vehicle, respectively, by performing communication between the own-vehicle and the another vehicle to which an optical signal is projected from the own-vehicle;
• and
• an information detecting unit configured to compare the identification code of the another vehicle received by the optical communication unit with the identification code of the another vehicle associated with the vehicle information of the another vehicle received by the DSRC communication unit, and obtain the vehicle information of the another vehicle received by the DSRC communication unit when the identification code of the another vehicle received by the optical communication unit and the identification code of the another vehicle received by the DSRC communication unit are identical,
• wherein the optical transmitting unit and the optical receiving unit of the optical communication unit are integrally embedded in at least a head lamp and a rear lamp of the own-vehicle.
