<p>A power steering apparatus which generates a steering assist force to be applied to a steering mechanism (1) by a hydraulic pressure generated by a pump (26) driven by an electric motor (27). The apparatus determines a rotation speed (R) of the motor (27) in accordance with a steering angular speed (W&thetas;) sensed when the steering mechanism (1) is operated. The motor (27) is driven at a lower motor rotation speed when the steering mechanism (1) is operated toward a steering angle midpoint than when the steering mechanism is operated away from the steering angle midpoint. <IMAGE></p> |
