摘　　要：以某微型纯电动汽车作为研究对象,以整车的动力性和续驶里程作为设计指标,通过理论计算匹配并验证了动力系统的关键参数。随后利用CRUISE仿真软件建立仿真模型并进行仿真。最后使用Matlab优化工具箱对汽车的传动比进行优化,并将优化前后的仿真结果与理论计算进行对比。仿真结果表明汽车动力系统的选择和匹配是合理的。A micro-electric vehicle is taken as the research object, and the vehicle＇s power performance and mileage are taken as design targets. Through theoretical calculation, the key parame- ters of power system are matched and verified. Then CRUISE simulation software is used to establish and simulate the simulation model. Finally, Matlab optimization toolbox is used to optimize the trans- mission ratio, and the simulation results before and after optimization are compared to the results ob- tained through theoretical calculation. The simulation result shows that the selection and matching of automobile powertrain are reasonable.
