<p>PROBLEM TO BE SOLVED: To efficiently, rationally and economically perform information communication between control computers with the small resources by dividingly setting a communication timing to be transmitted to a communication path according to the vehicular speed. SOLUTION: Respective control computers and a communication control circuit 3 are connected through interface circuits 1 and a multiplex communication path 2, information can be transmitted to respective control computers at a communication timing set on the basis of the same vehicular speed information, at the priority and at the operating mode, and the unification of information transmission can be performed. When the vehicular speed exceeds 30 Km/h, a vehicle is in the high-speed traveling state, and transmission of car-to-car distance display information from a car-to-car distance control computer 6 to a meter display control computer 8 is preceded. Moreover, a specified communication timing (for instant, 0.4 sec/per) is set, and an operating mode is set according to the information amount.</p> |
