Study on handling stability of four-wheel steering distributed drive electric vehicles
To study the impact of four-wheel steering technology on the handling stability of electric ve-hicles,a specific four-wheel steering(4WS)electric vehicle was taken as the research object,a two-degree-of-freedom model was established based on the relevant parameters.A dynamic simulation model of 4WS elec-tric vehicle was then built by using the dynamic simulation software CarSim,and low speed steering and high speed steering were simulated.The results show that compared with the traditional front wheel steering vehi-cle,the yaw rate fluctuation of 4WS electric vehicle is smaller,and it can resist the outside interference better 4WS system effectively improves the stability and safety performance of electric vehicle during high-speed and low-speed cornering.
