Dynamic performance optimization of four-wheel independent drive vehicle based on sliding mode control

Abstract

: This study mainly analyzes the influencing factors of four-wheel independent drive/independent steering in the process of vehicle operation, and establishes a two-degree-of-freedom dynamic model under the ideal condition. By changing the dynamic model of carsim, Realize the carsim model of four-wheel drive and MATLAB/simulink joint dynamic simulation, the output analysis results, for more accurate and more adaptable to the complex environment of the control to lay a theoretical analysis foundation, for the consideration of working conditions, four-wheel independent drive/independent steering vehicle in the process of motion stability is very important, through the ideal sliding mode control, Improve the handling stability of the car.
