Abstract

Provided is an electric power steering system that prevents the oscillation of the steering wheel at each steering stroke end. If the steering stroke end flag Fse is 1 or if the determination result is Yes in step S, the EPS-ECU () determines if the right steering flag (Fdrc) is 1 in step S. If the determination result is Yes, it is then determined if the steering torque difference base value (Dtsb) is positive in step S. If the determination result of step Sis Yes, the EPS-ECU () uses the steering torque difference base value (Dtsb) as the steering torque difference (Dts) in step S. If the determination result is No, the steering torque difference (Dts) is given by a value 0 in step S, and the control process is concluded.
