Abstract
The positions of position-controlled members provided on a car, for example, the driver's seat, steering wheel and mirrors, are controlled by a host position control unit through a plurality of position control units which are controlled on the basis of control signals transmitted from the host position control unit. After receiving the signal transmitted from the host position control unit, each position control unit sends a 1-pulse answer signal to the host position control unit through a returning unit. When the returning unit sends no answer signal in response to a control signal transmitted from the host position control unit, an abnormality recognizing device recognizes the fact that there is an abnormality in the communication system. Accordingly, any abnormality occurring in the communication system is promptly detected and it is therefore possible to quickly cope with the abnormal situation.
