“…The wire-controlled drive system structure for new energy vehicles is mainly divided into three types: centralized drive, central transmission drive, and distributed drive. At present, electric drive bridge technology, wheel edge deceleration drive, and hub motor direct drive technology are mainstream structures [57][58][59].…”

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.

The purpose is to study the handling stability and energy saving mode of energy saving electric vehicles. First, the differences between electric vehicles and traditional fuel vehicles are analyzed. Moreover, based on active safety technology, the control stability, handling stability and driving safety of electric vehicles are improved. Then, based on the vehicle dynamics theory and the proposed assumptions, the modular electric vehicle dynamics model is established, including the wheel model, tire model and driver model, which can effectively control the error of the vehicle model and reduce the difficulty and complexity of vehicle modeling. Next, based on the model predictive control theory, the vehicle steady-state control strategy is established, which can predict and control the state of the electric vehicle in the compound condition and improve the control stability of the vehicle. Finally, the vehicle dynamic model and steady-state control system are simulated and tested. The experimental results show that the simulation results of the established dynamic model of the electric vehicle in angle step condition and single line shifting condition are consistent with the results of professional software, which shows that the established dynamic model can accurately describe the dynamic state of electric vehicle and provides the basis for the research of vehicle stability control strategy. Experimental results of the control strategy under the condition of double line shifting show that the designed control strategy can accurately track the state of the system and constrain the deviation in a small range, so as to ensure the driving stability of the electric vehicle. This exploration provides a reference for the study of dynamic analysis and handling stability control strategy of electric vehicles.
