Patent ID: 7181326

Claim:
A method for providing active front steering for a vehicle, said method comprising: providing a vehicle speed signal of the vehicle; providing a lateral acceleration signal of the lateral acceleration of the vehicle; providing an actual yaw rate signal of the actual yaw rate of the vehicle; providing a steering angle signal indicative of the vehicle operator's desired steering direction; determining a desired yaw rate of the vehicle based on the steering angle signal and the vehicle speed signal; determining a desired side-slip rate of the vehicle based on the steering angle signal and the vehicle speed signal; determining a yaw rate feedback signal based on the desired yaw rate signal and the actual yaw rate signal; determining a side-slip rate feedback signal based on the desired side-slip rate signal, the vehicle speed signal, the actual yaw rate signal and the vehicle lateral acceleration signal; and integrating the yaw rate feedback signal and the side-slip rate feedback signal to generate a stability enhancement control signal used for providing the active front steering of the vehicle, wherein integrating the yaw rate feedback signal and the side-slip rate feedback signal includes weighting one or both of the yaw rate feedback signal and the side-slip rate feedback signal.
