ABSTRACT:
An electric power steering system includes a steering torque detecting device for detecting a steering torque applied between an input shaft connected to a steering wheel and an output shaft connected to a steering gear in response to an elastic deformation of an elastic member connecting the input shaft with the output shaft, an electric motor whose rotation is controlled by a control signal from a control device in response to a detecting signal from the steering torque detecting device, and a clutch device interposed between the electric motor and the output shaft and controlling an intermittent transmission of the rotation of the electric motor to the output shaft in response to the elastic deformation of the elastic member. Thereby, it is possible to improve the safety performance, the reliability and the steering wheel feeling of an electric power steering system.
