ABSTRACT

In order to improve the transmission efficiency as well as the range of centralized drive electric vehicle and simplify the structure of the whole vehicle, a distributed drive electric vehicle is adopted. Taking a single-motor centralized drive electric vehicle as a reference object, the original model was changed to a distributed drive model according to the structural of distributed power system electric vehicles. The Cruise software is used to establish two types of electric vehicle models, centralized and distributed, and to verify the correctness of the centralized model based on the experimental data of the actual driving of the original vehicle. Analyzing the simulation results of dynamic and economy of the two models, it can be concluded that all the indicators of distributed electric vehicles meet the target requirements, and the performance of distributed electric vehicles is better than that of centralized electric vehicles.
