<p>PURPOSE:To accomplish lighter steering operation by changing the driving force of the control mechanism according to the magnitude of the controlling force and the control direction of the steering wheel detected. CONSTITUTION:A positive or negative voltage is generated in resistance pieces a and b on a strain gauge in a differential amplifier 10 in proportion to the magnitude of controlling force and the control direction of the steering wheel 1. After amplified, the voltage is applied on a motor 8. The motor, a magnet motor, rotates positively or reversely depending on the voltage direction of the armature terminal. The motor 8 whose output is performed by the screwing or unscrewing of a ball screw gives the control mechanism a controlling force to ensure that it can follow the steering wheel control smoothly.</p> |
