摘要： 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.

摘要： Electric power steering system comprises an electric motor (9) for producing a steering assist force reducing a steering effort of a vehicle operator and a control unit (21) determining a control value for the electric motor, the control unit being configured to determine the control value by selecting a map representing a relationship between a vehicle state variable and a control value for each of a plurality of control modes. When switching control modes, the control unit gradually changes the control value from that obtained from a map corresponding to a preceding control mode to that of a following control mode. A different time period of gradual transition from the preceding control mode to the following control mode is selected depending on those control modes.
