Abstract

PURPOSE:To obtain a car communication controlling system which never invades a privacy by giving a new car number to a road running car which enters the communication area of a road equipment. CONSTITUTION:When running cars 2a, 2c and 2d enter the communication area of a road equipment 1a, unnumbered-car information on the running car 2a is received by the road equipment 1a, which transfers the information to a center 3. The center 3 sends out a car number (n), which is not used, to the running cars 2a, 2c and 2d through the road equipment 1a. Athough the cars 2a, 2c and 2d receives and stores the car number (n), the car 2a receives it first and returns the received car number (n) to the road equipment 1a, which resends the car number (n) to those cars. Since the car 2a has sent the car number (n) already, it does not changes the car number (n) stored in its storage part, but the cars 2c and 2d reset the car number (n) stored in their storage parts. Similarly, a car number (n+1) is set in the running car 2c, and a car number (n+2) is set in the running car 2d.
