ABSTRACT:
The amount of wiring required in a steering control system is reduced, and a power loss which occurs in the wiring of the power system is also reduced. The influences of electric noises upon the wiring between sensors and a control unit is reduced, thus improving the reliability. The control unit 9 connected with sensors and a servo unit SVU each include an independent computer 1, 8, and are connected to each other through a communication line. The control unit 9 is disposed adjacent to the sensors, while the servo unit SVU is disposed adjacent to an actuator. Information relating to a target steer angle and which is transmitted is chosen to be a variance T.DELTA. thereof, and on the receiving end, T.DELTA. is accumulated to obtain a target steer angle T.theta.. A steer angle deviation 0e is transmitted from SVU to the control unit 9. The presence or absence of any abnormality occurring is examined by checking the period of signal reception and signal values.
