Abstract
A microcomputer o n EPS performs failure diagnosis of a motor or a motor driving circuit after an ignition switch is turned on and before an ECU starts control of power supply to the motor. When an angular velocity of the motor rotatable with a steering wheel is greater than a predetermined value, the failure diagnosis is not made. Thus, a period from the turn-on of the ignition switch to the start of current supply control is shortened.
