Abstract
A first system and a second system include a first motor and a second motor for driving a steering mechanism in dependence on the rotational manipulation of a steering wheel. A first ECU and a second ECU mutually monitor abnormalities of the systems each to stop an abnormal system. When the respective systems are normal, the first ECU and the second ECU drivingly control the first motor and the second motor of their own systems to drive the steering mechanism by cooperation of the respective motors. When either one of the both systems is abnormal, the ECU of the other system solely drivingly controls the motor of its own system thereby to drive the steering mechanism. Thus, it can be realized to make the systems low in cost irrespective of the provision of the plural systems.
