  • Rear steering sensor diagnostic algorithm for four-wheel steering systems
    Patent number: 8024088
    Abstract: A method for controlling the rear steering angle of a vehicle includes receiving a plurality of signals indicative of rear steering angle; checking at least one of the plurality of signals to determine if it falls within a valid range; correlating at least a first signal of the plurality of signals with at least a second signal of the plurality of signals to determine if either the first signal or the second signal is invalid; and rejecting any signals found to be invalid.
    Type: Grant

  • Wheel and steering sensor system
    Patent number: 7347433
    Abstract: A steerable element angular sensor system may include a sensor having a sensing axis positioned along an axis of rotation of a knuckle, a connector connecting a yoke and a knuckle of a steering system. The sensor may detect rotation of at least one of the knuckle and the connector. Also, the sensor system may include protection from rotation detection interference from linear and angular movements of at least one of the connector and the knuckle. The sensor system may be included within a steerable element assembly and provided within a vehicle.
