摘要： A hydraulic power steering apparatus assists in steering of a vehicle with a hydraulic cylinder. The hydraulic power steering apparatus includes a flow control valve, a steering torque sensor, a steering angle sensor, a vehicle speed sensor, and an ECU. The flow control valve changes the supply/drainage amount of hydraulic fluid for the hydraulic cylinder. The ECU sets a supply/drainage mode for supplying/draining the hydraulic fluid with respect to the hydraulic cylinder based on detection results from the aforementioned sensors and controls the flow control valve in accordance with the supply/drainage mode of the hydraulic fluid.

摘要： A pump rotation speed correcting unit includes a valve opening degree command differential value computing unit, a pump rotation speed correction value computing unit, and a correction value adding unit. The valve opening degree command differential value computing unit computes a temporal differential value of a valve opening degree command value that is set by a valve opening degree command value setting unit. The pump rotation speed correction value computing unit 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 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.
