摘要

The anti-lock braking system based on multi-body dynamic and control theory is researched. Multi-body vehicle dynamic model is built in ADAMS/Car and suspension system, tire model, braking system, engine system, steer system, vehicle frame are included. The non-linear characteristics of tire, bushing, spring and damper is considered, so it can accurately express the dynamics performance of the vehicle. Besides, logic threshold control model of ABS based on wheel deceleration and slip rate is designed under Matlab/Simulink environment, and the two models are integrated and co-simulation by the interface of ADAMS/Control. Simulation results that based on different arrangement of ABS system are compared with general brake results. Analysis results indicate that vehicle braking performance is improved with shorter braking distance and less lateral displacement, so vehicle with ABS has much more practical significance
