| Abstract: | A new control strategy for Anti lock Braking System is developed to improve the vehicle braking performance during the emergency maneuvers. Firstly, a control strategy is designed by setting up a simple dynamic vehicle model under braking with two degrees of freedom. To improve the evaluated control strategy, conjugate boundary method and Poincare mapping concept are applied. Secondly, the prediction and re selection method is used with a nonlinear vehicle model and a nonlinear tire model. At last, various control strategies are simulated with computer. The result of simulation shows that the new method is more effective during emergency braking than the old ones. |
