ABSTRACT:
A multiplex transmission system for vehicles having a plurality of multiplex nodes connected to a transmission path in order to communicate information therebetween for controlling a vehicle. Each of the multiplex nodes a priority code which indicates a priority of the signals to be transmitted with the data when a plurality of multiplex nodes concurrently transmit data and accordingly the signals therefrom collide with each other. The priority data includes a first priority which attaches importance to high responsiveness for the engine and a second priority which attaches importance to safety. A detector is provided for detecting the traffic condition in the multiplex transmission path. A priority changer is provided for changing the priority respectively in accordance with the traffic condition, so that proper control of both response and safety can be reconciled.
