Abstract
An inter-vehicle communication method according to the present invention performs communication by sequentially relaying transmission information among vehicles. For broadcasting the transmission information to peripheral vehicles, a vehicle transmitting the transmission information designates relay vehicles and causes the relay vehicles to broadcast reception information to peripheral vehicles of the relay vehicles. In order to designate the relay vehicles, the vehicle transmitting the transmission information receives positional information from its peripheral vehicles, identifies branch roads on which the respective peripheral vehicles exist by referring to map information, and designates as relay vehicles peripheral vehicles farthest away from the vehicle transmitting the transmission information on the respective branch roads.
