Vehicle-to-vehicle communication system
First Claim
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, a vehicle-to-vehicle communication device provided in a subject vehicle, the device 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; and
a communication controlling unit that (i) refers to the communication conditions stored in the communication condition storing unit, (ii) controls the communicating unit under a communication condition corresponding to a communication wavelength assigned to the subject vehicle to transmit information to other vehicle-to-vehicle communication devices, and (iii) controls the communicating unit under a communication condition corresponding to a communication wavelength assigned to a nearby vehicle to receive information transmitted from a vehicle-to-vehicle communication device mounted in the nearby vehicle.

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.

10. 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,
a vehicle-to-vehicle communication device provided in a subject vehicle, the device comprising: -
a communication wavelength storing unit that stores a communication wavelengths, which are assigned to the subject vehicle and nearby vehicles for transmitting data;
a communicating unit for transmit data to a vehicle-to-vehicle communication device mounted in a nearby vehicle by using a first communication wavelength assign to the subject vehicle and for receiving data from a vehicle-to-vehicle communication device mounted in a certain nearby vehicle by using a second communication wavelength assigned to the certain nearby vehicle; and
a communication wavelength amending unit that refers to data stored in the communication wavelength storing unit and amends the first communication wavelength to a third communication wavelength different from the second communication wavelength when determining that the first communication wavelength assigned to the subject vehicle and the second communication wavelength assigned to the certain nearby vehicle are identical with each other.
