Abstract
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.
