Abstract:
1. A vehicle-to-vehicle communication system including a plurality of vehicle-to-vehicle communication devices that are mounted in vehicles and communicate with one another, and a vehicle-to-vehicle communication device provided in a subject vehicle, the vehicle-to-vehicle communication device provided in the subject vehicle comprising: a communication wavelength storing unit that stores communication wavelengths assigned to the subject vehicle and nearby vehicles; a communication condition storing unit that stores communication conditions with respect to communication wavelengths stored in the communication wavelength storing unit; a communicating unit for communication with other vehicle-to-vehicle communication devices mounted in the nearby vehicles; a communication controlling unit that an identity determining unit that refers to data stored in the communication wavelength storing unit and determines whether or not a communication wavelength assigned to the subject vehicle and a communication wavelength assigned to a nearby vehicle are identical with each other; and a first storage controlling unit that, when it is determined by the identity determining unit that the communication wavelength assigned to the subject vehicle and the communication wavelength assigned to the nearby vehicle are identical with each other, changes the communication wavelength assigned to the subject vehicle so that a new communication wavelength is not identical with the communication wavelength assigned to the nearby vehicle, and updates data stored in the communication wavelength storing unit with the new communication wavelength newly assigned to the subject vehicle, wherein the vehicle-to-vehicle communication device provided in the subject vehicle further comprises:
