Abstract
A power steering apparatus which generates a steering assist force by a hydraulic pressure generated by a pump driven by an electric motor. The power steering apparatus actuates the electric motor in its off state, on condition that a change amount of a steering angle exceeds an actuation threshold. A first actuation threshold which is to be employed when a steering wheel is operated away from a steering angle midpoint and a second actuation threshold which is to be employed when the steering wheel is operated toward the steering angle midpoint are determined in accordance with a sensed steering angle so that the sum of the first and second actuation thresholds is virtually constant.
