摘　　要：为了使电动汽车在满足动力性能要求的前提下,具有更佳的经济性,根据整车性能要求对动力系统参数进行匹配与选型,基于AVL cruise软件建立整车模型,仿真分析整车的动力性与经济性。基于Pointer优化算法对主减速比进行优化,分析对比优化前后整车的动力性与经济性。结果表明,通过对电动汽车主减速比的优化,可以在满足整车动力性性能指标的要求下,得到更佳的经济性。To make electric vehicles more economical under the premise of meeting the performance requirements, according to its performance requirements, the power system parameters are matched and selected, and the vehicle model is built based on AVL cruise software which is used to simulate and analyze its power and economy. Based on the Pointer optimization algorithm, the main reduction ratio is optimized, and the power and economy of the whole vehicle before and after the optimization are analyzed and compared. The results show that by optimizing the main reduction ratio, it is possible to obtain better economy under meeting its power requirements.
