  • Patent number: 7213675
    Abstract: A method for implementing anti-static steering for vehicle steering systems includes receiving a desired rear wheel angle input and receiving a vehicle speed input. An approved rear wheel angle output is generated using the desired rear wheel angle input and the vehicle speed input, wherein the approved rear wheel angle is based upon one of a plurality of defined operating states, the plurality of operating states including operation at a speed in a first range, operation at a speed in a second range, and transitions therebetween.
    Type: Grant

  • Publication number: 20050043874
    Abstract: A control system for a steering system in a vehicle comprising: a reference model responsive to an operator input that computes desired states of the vehicle; a feedforward controller in operable communication with the reference model. The feedforward controller computes a first control value based on input from said reference model and based on at least one of: a lateral velocity, a rate of lateral velocity, a lateral acceleration, and a combination, wherein the combination includes a yaw rate with at least one of a lateral velocity, a rate of lateral velocity, and a lateral acceleration of the motor vehicle. The system also includes an actuator for affecting the steering system based on the first control value, the actuator in operable communication with the feedforward controller.
