Abstract:
In an electric power assisting system for a vehicle, a control unit receives an input shaft rotation angle detected by an input shaft rotation angle sensor and an output shaft rotation angle detected by an output shaft rotation angle sensor. The control unit controls rotation of a motor based on the detected two rotation angles. The control unit differently controls the rotation of the motor whether torque is applied from a steering wheel side or from a road surface side.
