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 S8, the EPS-ECU (21) determines if the right steering flag (Fdrc) is 1 in step S10. If the determination result is Yes, it is then determined if the steering torque difference base value (Dtsb) is positive in step S11. If the determination result of step S11 is Yes, the EPS-ECU (21) uses the steering torque difference base value (Dtsb) as the steering torque difference (Dts) in step S12. If the determination result is No, the steering torque difference (Dts) is given by a value 0 in step S13, and the control process is concluded.
