| Abstract: | According to the characteristics of the vehicle brake, the main stages of automobile brake are analyzed, the main factors of affecting vehicle brake are discussed, the dynamic model of tire rotation and half vehicle braking model are established. An anti lock braking system with sliding mode variable structure is proposed, and a braking law based on exponential approach law is adopted. The simulation results show that the method can improve the braking performance of the vehicle, shorten the braking distance and effectively suppress the jitter phenomenon. |
