Based on the selection of basic vehicle parameters and the determination of performance indicators, this paper carries out the design matching of dynamic performance parameters of pure electric vehicles. Then, a pure electric vehicle dynamic simulation model is established by vehicle simulation software, and the vehicle dynamic performance index is simulated and analyzed by inputting relevant parameters. Finally, the rationality of simulation model and parameter matching is verified by real car test. This study can provide theoretical basis for the matching design of various systems in the initial stage of pure electric vehicles, carry out range and performance test evaluation of vehicle performance, and provide reference for the analysis of dynamic performance and economic index of pure electric vehicles.
