“…The suspension system and the composite braking system are coupled by the tire model. The vertical load Fz1 and Fz2 of tire model are applied by the suspension model, and the tire model outputs ground adhesion Fx1 and Fx2 to the composite braking system when the vehicle is running [16][17][18]. Due to the existence of braking inertia, the suspension will have pitching, so the composite braking model outputs the compensating pitching moment T to the suspension system.…”

As pure electric vehicles add the braking energy recovery function, the coordinated control between the chassis brake subsystem and the suspension subsystem faces new challenges. In this paper, the fuzzy coordinated control strategy between composite braking and active suspension is used to improve the braking energy recovery performance and braking safety. Based on the tire longitudinal mechanics test, a tire longitudinal mechanics model was established. Meanwhile, designed a fuzzy coordinated control strategy combined with a compound braking model and active suspension integrated dynamics model. Carsim and Simulink joint simulation was used to verify the coordinated control performance. The research results show that the coordinated control strategy designed in this paper has greatly improved the composite braking performance and improved the overall performance of the vehicle chassis while sacrificing the performance of a small part of the suspension.
