以某款纯电动轻卡为研究对象,按照所设定的整车动力性和经济性指标,对动力系统各部件参数进行匹配设计,集成整车仿真软件Cruise和优化软件Isight进行联合仿真,依据优化算法理论,设计合理的组合算法对变速器各挡传动比进行优化。结果显示,优化后的百公里能耗降低了12.8%,续航里程提升了14.8%。 Taking a pure electric light truck as the research object, the parameters of the powertrain system are designed and matched according to the vehicle dynamics and economic indicators set up. The Cruise and the optimization software Isight are integrated to simulate the optimization. Algorithm theory, a well-designed combination of algorithms to optimize the transmission gear ratio. The results show that the optimized energy consumption per hundred kilometers has been reduced by 12.8% and the mileage has been raised by 14.8%.
