Zusammenfassung:When only one of sensor signals (Sa, Sb) generated by the plural systems and output from a torque sensor (14) is normal, a control variable restriction processing part (29) performs an assist restricting process for setting an upper limit value and a lower limit value of a basic assist control variable (µ_as) in accordance with at least one of the lateral acceleration (g), the steering angle (¸s), the steering speed (ws), or the yaw rate.
