Lane keeping Control Based on PWA Vehicle Model
When the road surface adhesion coefficient is low,the tire cornering force exhibits strong nonlinearity.In this situation,the general 2DOF(degree-of-freedom)vehicle model is deviated from the actual vehicle model,and the controller performance based on the model is inevitably reduced.In this paper,we use PWA(Piecewise Affine)method to linearize the lateral force of vehicle tire.Based on the PWA(Piecewise Affine)vehicle model and lateral driver model,the optimal steering wheel angle is calculated and the lane keeping controller is designed.The simulation results show that the performance of the lane keeping controller is better than that of the controller designed based on the general 2 DOF vehicle model when the road surface adhesion coefficient is low.
