纯电动汽车传动系统参数匹配及优化

Parameters Matching and Optimization for Power-train of Electrical Vehicle

纯电动汽车的传动系统参数匹配是车辆节能设计的关键,关系到整车经济性与动力性的表现。为实现纯电动汽车传动系统参数的合理匹配与优化,以整车动力性能和续驶里程要求为设计依据,实现对某纯电动汽车电机、电池、减速器的参数匹配。并运用人群搜索算法对汽车传动系统参数进行优化,优化结果在AVLCruise软件仿真中表现出较好的整车综合性能。

The parameter matching of transmission system of pure electric vehicle is the key of vehicle energy-saving design,which is related to the performance of vehicle economy and power. In order to realize the reasonable matching and optimiza-tion of transmission system parameters of pure electric vehicle, the parameters matching of motor, battery and reducer of a pure electric vehicle is realized on the basis of vehicle power performance and driving mileage requirements. SOA is used to optimize the parameters of the automobile transmission system, and the optimization results show better comprehensive performance in the simulation by using AVL Cruise.
