| 20090292421 | STEERING APPARATUS - An apparatus for use in turning steerable vehicle wheels upon manual rotation of a hand wheel includes a torque sensor connected with the hand wheel. A controller is connected with the torque sensor and a rear steering gear. The controller is operable to effect operation of 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 torque sensor has an output which corresponds to a torque which is less than the predetermined torque throughout turning of the front wheels through a first range of turning movement. The torque sensor has an output which corresponds to a torque which is at least as great as the predetermined torque which occurs when turning of the front wheels during a second range of turning movement of the front wheels. The controller is operable to effect operation of the rear steering gear in response to the output from the torque sensor through the 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. The controller being operable to effect operation of the rear steering gear in response to the output from the torque sensor through the 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 to the steering angle of the front wheels. | 11-26-2009 |
