Abstract
A vehicle-to-vehicle communication device mounted in a subject vehicle includes (i) a transmitter-receiver for communication with other vehicle-to-vehicle communication devices mounted in other vehicles, (ii) a memory that stores communication wavelengths assigned to the other vehicles, and (iii) a communication control unit. When a certain vehicle is determined to be within a dangerous distance from the subject vehicle, the communication control unit refers to a communication wavelength assigned to the certain vehicle stored in the memory. When the communication wavelength assigned to the certain vehicle is identical to a communication wavelength assigned to the subject vehicle, the communication wavelength assigned to the subject vehicle is changed to another communication wavelength different from the communication wavelength assigned to the certain vehicle.
