ABSTRACT:
A electric motor, which drives a fluid pressure pump used to derive a steering assist force, is controlled in a required manner using a simplified arrangement. Specifically, a pump 11 which feeds a fluid pressure in order to produce an assist force is driven by a D.C. brushless motor 11 which is provided with means 18 for detecting a rotational position of a rotor 23 thereof. Motor control means 14, 15 drives and controls the motor to rotate at a given number of revolutions. Vehicle speed detecting means 16 detects a running speed of a vehicle. The motor control means controls the number of revolutions of the brushless motor on the basis of information representing a vehicle speed, a number of revolutions of the rotor which is determined by utilizing a signal from the rotor position detecting means, and information from means which detect a steer angle and a steering angular rate.
