Research on multi-system integrated and coordinated control of automotive chassis

In this paper, we analyze automotive chassis system modeling and subsystem control to construct a nonlinear chassis system by analyzing the dynamics of the whole vehicle, handling process, and manufacturing process. Secondly, the integrated braking system decoupling controller is designed to control both friction and electromagnetic integrated brake systems effectively. Finally, the Simulink simulation model is integrated into Matlab software to conduct an imitation study of the control system. When the brake controller is activated, the findings show that the wheel’s slip rate drops to almost 0.2, which is close to the desired value. The vehicle’s braking distance with conventional braking is close to 40m, but it is reduced to about 30m under the action of the ABS system, which effectively shortens the braking distance and ensures the vehicle’s safety in braking.
