Feedforward control of motor vehicle roll angle |
摘要 |
A technique for reducing excessive motor vehicle roll angle using a feedforward control comprises a number of steps. Initially, a steering angle and a speed of the-motor vehicle are determined. Next, a lateral acceleration of the vehicle is estimated based on the steering angle and the speed. Then, a lateral acceleration proportional and derivative (PD) term of the estimated lateral acceleration is determined and roll angle reduction is implemented when the lateral acceleration PD term exceeds a first threshold. The roll angle reduction may be achieved through application of a braking force to an outside front wheel of the vehicle. A magnitude of the braking force may be proportional to a difference between the lateral acceleration PD term and the first threshold.
