Power steering apparatus

摘要

A vehicle power steering apparatus for performing power steering by rotating a motor in accordance with a steering torque acting on input and output steering shafts and driving a steering direction control unit to perform power steering, comprises a sensor for generating an electrical signal corresponding to a displacement of a movable member displaced by a rotational force acting on the steering wheel; a controller for rotating the motor at a torque represented by the electrical signal during an ON time of the electrical signal generated from the sensor; and moving means for moving the movable member in a direction to cancel the displacement of the movable member driven by the motor.
