| Abstract: | The nonlinear characteristics of tire were taken into account in this paper,and the Magic Formula was adopted in setting up the nonlinear vehicle mechanics model.A forward BP artificial neural network was used to identify this nonlinear model and another one was used to identify the parameters of PID controller.The discrete control system and control algorithm were designed.The simulation results show that nonlinear model can effectively improve the stability of four wheel steering in vehicles. |
