ABSTRACT:
A motor-operated power steering apparatus comprises an electric motor for generating assistive steering power in a steering force transmitting system, steering force detecting means for detecting the steering force in the steering force transmitting system and generating a steering force signal indicative of the detected steering force, temperature detecting means for detecting the temperature of the steering force transmitting system and generating a temperature signal indicative of the detected temperature, correcting means for correcting the steering force detected by the steering force detecting means based on the temperature detected by the temperature detecting means to determine a corrected steering force, current value determining means for determining a target current value based on the corrected steering force and generating a target current control signal indicative of the determined target current value, and energizing means for supplying a current of the target current value to the motor based on the target current control signal from the current value determining means.
