摘要： A pump rotation speed correcting unit (63) includes a valve opening degree command differential value computing unit (71), a pump rotation speed correction value computing unit (72), and a correction value adding unit (73). The valve opening degree command differential value computing unit (71) computes a temporal differential value of a valve opening degree command value that is set by a valve opening degree command value setting unit (52). The pump rotation speed correction value computing unit (72) computes a correction value of a pump rotation speed command value on the basis of the valve opening degree command differential value. The correction value adding unit (73) adds the pump rotation speed correction value to the pump rotation speed command value that is set by the pump rotation speed command value setting unit (62).

摘要： A motor (27) is stopped when a steering angular speed (VΘ) is not greater than a stop threshold (VS) and a motor electric current value (Im) is kept within a motor stop range (ΔI) for a predetermined time period. The value of a steering torque (T) increases as the motor electric current value (Im) increases. Therefore, the motor (27) can assuredly be stopped when the steering torque (T) is small. Such motor stop range (ΔI) is defined by a range starting from the non-load electric current value (I0), which is calculated for compensating its variation depending mainly on the temperature of the working oil. Further, when the motor is off, the sensitivity for motor actuation with respect to a change in the steering angle (Θ) is set higher as the value of the steering angle increases.

摘要： A damping control unit (62) sets a damping torque command value (TD*) that corresponds to a steering angular velocity (ωh) when a direction of a detected steering torque (Th) is a turning direction, a magnitude (absolute value) of the detected steering torque (Th) is larger than or equal to a first threshold (A1) (A1 ≥ 0), a direction of the steering angular velocity (ωh) is a returning direction and a magnitude (absolute value) of the steering angular velocity (ωh) is higher than or equal to a second threshold (B1) (B 1 ≥ 0). An addition unit (63) adds the damping torque command value (TD*) generated by the damping control unit (62) to a basic assist torque command value (TAO*) set by a basic assist torque command value setting unit (61).
