Method and system for adaptively compensating open loop front-wheel steering control |
摘要 |
An active front-wheel vehicle steering control system that employs open-loop control that includes an adaptive compensation sub-system that compensate for changes in vehicle dynamic parameters. The control system includes a dynamic parameter estimation sub-system that provides an estimated understeer coefficient based on a front-wheel steering angle signal, a vehicle lateral acceleration signal, a vehicle yaw rate signal and a vehicle speed signal. An open-loop control sub-system generates a steering angle control signal for controlling steering of the front wheels using a combination of a nominal open-loop steering angle control signal and a corrected open-loop steering angle control signal that is based on a real-time estimated understeer coefficient.
