Abstract
A power steering device has a hydraulic actuator that generates steering assistance power by using hydraulic fluid fed from a pump driven by a brushless electric motor. The device controls the motor's rotation speed to have a preset steering assistance speed in a steering assistance mode, and a preset standby speed in a steering assistance release mode. The motor rotation speed is set to the steering assistance speed after being set to a maximum speed that exceeds the steering assistance speed in the steering assistance mode.
