Abstract
An apparatus for use in turning steerable vehicle wheels upon manual rotation of a hand wheel includes a torque sensor connected with a torque sensor and a rear steering gear. The controller selectively controls the rear steering gear in response to an output from the torque sensor upon manual application of at least a predetermined torque to the hand wheel. The controller selectively controls the rear steering gear in response to the output from the torque sensor through a first range of turning movement of the front wheels so that the steering angle of the rear wheels has a first relationship to the steering angle of the front wheels and through a second range of turning movement of the front wheels so that the steering angle of the rear wheels has a second relationship different from the first relationship.
