ABSTRACT:
A power steering apparatus includes a motor, a torque sensor, and a motor resolver. The motor generates an assisting force to reduce the steering force of the steering wheel. The torque sensor detects the steering torque of the steering wheel. The motor resolver detects the rotational angle of the motor. An electronic control unit (ECU) detects the absolute position of the steering wheel based on a detection signal Rt sent from a second resolver of the torque sensor and a detection signal Rm sent from a motor resolver. As a result, the cost is reduced and the absolute position of the steering wheel is accurately detected.
