1. A method of inter-vehicular communication between a plurality of vehicles comprising the steps of:
- (a) assigning, in order, identification numbers to each of the vehicles in the plurality of vehicles;
(b) transmitting from each vehicle to at least one other vehicle, in order, starting from a smallest identification number, information including the identification number of the vehicle;
(c) wherein a first transmission from the vehicle having the smallest identification number functions as a reference time and wherein the first transmissions from the other vehicles and succeeding transmissions from all vehicles start after a predetermined time delay from the reference time; and
(d) wherein the vehicle identification numbers are assigned as the vehicles pass an identification number assigning means positioned along a road.

Abstract
To provide an inter-vehicular communication method which enables a plurality of vehicles to efficiently exchange information. A plurality of vehicles are assigned identification numbers (IDs) and perform transmission of information in order, on the basis of their identification numbers. A time which is allocated so that each of the vehicles can perform a transmission, is constant (one cycle=4 ms), and a time at which the vehicle of ID=1 starts its first transmission is set as a reference time. The vehicles of ID=2, ID=3 and ID=1 . . . sequentially perform their transmissions 4 ms, 8 ms and 12 ms . . . after the reference time. Thus, it is possible to avoid a problem that the plurality of vehicles perform their transmissions at the same time, and it is also possible to minimize the waste of time and to exchange information in a short time.
