Abstract
A power steering apparatus for a vehicle having a hydraulic mechanism for generating a force applied to a steering mechanism for reducing a force needed to operate a steering member (wheel). A device is provided for determining a condition wherein a yaw rate generated in the vehicle does not match a steering operation of the steering member. A hydraulic or electric torque motor is operated for generating a counter steering force applied to the steering mechanism, to cancel the yaw rate which does not match the operation of the steering member.
