ABSTRACT:
An electronic controlled power steering apparatus is disclosed, in which the force required for manipulating the steering wheel is varied in accordance with not only the velocity of an automobile and but also with the steering angle, so that safety will be ensured during the running of an automobile. When sensing signals for the velocity of an automobile is other than normal, the force required for manipulating the steering wheel is maintained at a constant value regardless of the running state of the automobile, whereby an erroneous operation such that the force required for manipulating the steering wheel is varied by an abnormal velocity sensing signal is prevented.
