<p>A communication system for a vehicle in which mutual communication is performed between a central station and a plurality of peripheral stations via a communication signal line, wherein with respect to the above mentioned peripheral stations, a communication signal from the central station is inputted via the communication signal line, which is outputted to an output circuit 16 via a shift resistor B and a resistor B so as to drive and control the driven items (lamps and the like). In addition, a continuity control circuit 103 is controlled during a period from a state in which supply of an electric power supply voltage from a battery carried on the vehicle to the peripheral station is started until the peripheral station receives a first communication signal from the central station so as to electrically separate connection between the resistor B and the output circuit 16. In such a case, the output circuit 16 is connected such that the above mentioned control system is subjected to drive control in a desired initial state irrelevant to the above mentioned communication signal. And when the first communication signal from the central station is received, drive control of the above mentioned control system is carried out in accordance with the communication signal.</p> |
