ABSTRACT:
A power steering apparatus having a torque sensor for detecting steering force, an actuator for assisting the steering force according to the torque detected by the torque sensor, two vehicle speed sensors for detecting vehicle speed, and a microcomputer for controlling the actuator according to the detection results by the vehicle speed sensors. When the difference between the vehicle speed values detected by the two vehicle speed sensors becomes greater than a predetermined value, the greater vehicle speed value of the two is integrated to obtain a control vehicle speed value for control of the actuator. When the vehicle speed value difference is greater than the predetermined value and remains in that state for more than a predetermined duration of time, either a predetermined vehicle speed value is set as the control vehicle speed value or the operation of the actuator is disabled.
