<p>PROBLEM TO BE SOLVED: To provide a control device for electric power steering device, which measures or presumes the temp. of a motor, corrects the motor current command value with the measurement or the presumptive value, and performs a compensative control for a change in the motor current characteristic resulting from a temp. change. SOLUTION: A control device of an electric power steering device is equipped with a torque sensor 10 to sense the steering torque of a steering wheel, a motor 20 to auxiliarily energize a steering shaft installed in a single piece with the steering wheel, and a control unit 30 to operate the motor 20 in compliance with the size of the steering torque, wherein the control unit 30 corrects the motor current command value on the basis of the measured value or presumed value of the motor temp. and controls the motor current with the corrected motor current command value.</p> |
