两挡纯电动汽车性能仿真与换挡策略优化

Performance Simulation and Optimization of Shifting Strategy for Two-speed Pure Electric Vehicle

以某型搭载了两挡变速器的纯电动汽车为研究对象,重点分析匹配其关键动力系统参数,并在Matlab/Simulink环境下搭建整车仿真模型,对研究车型动力性经济性进行仿真分析,校核匹配参数的可行性,最后提出换挡策略的优化方案,为研究车型的项目开发提供参考。

With a two-speed pure electric vehicle as the research object,the paper focuses on analysis of matching the key power system parameters,and simulates the dynamic economy of the research model by setting up the vehicle simulation model in Matlab/Simulink environment.Then the feasibility of the matching parameters is checked.Finally the optimization scheme of shifting strategy is put forward,which provides a reference for project development of research vehicle.
