摘　　要：为缩短对某款纯电动多用途汽车(MPV)整车研发周期,提出了一种基于AVL Cruise的经济性优化设计.首先根据整车设计参数,对MPV驱动电机、动力电池、传动系统等参数进行了匹配.然后基于AVL Cruise软件搭建整车仿真模型,对模型进行动力性和经济性分析,仿真结果验证纯电动MPV满足动力经济性指标,验证了动力性和经济性分析方法的合理性.最后为了提高车辆的经济性,对MPV的减速比进行了优化,目标函数为车辆在新欧洲驾驶循环(NEDC)工况下百公里的电耗.仿真结果表明,优化前后,NEDC工况下百公里电耗降低2.4%,全球统一轻型车辆测试程序(WLTP)工况下百公里电耗降低2.5%.In order to shorten the research and development cycle of a battery electric multi-purpose vehicle(MPV),this paper proposes an economy optimization design based on AVL Cruise.Firstly,according to the design parameters of the vehicle,the MPV driving motor,power battery,transmission system and other parameters are matched.Then the vehicle simulation model is built based on AVL Cruise software;analysis on dynamic property and economy of the model is carried out;the simulation results verify that the battery electric MPV meets the dynamic economy indicators,and also verify the rationality of the analysis methods for the dynamic property and economy.Finally,in order to improve the economy of the vehicle,the deceleration ratio of the MPV is optimized,and the objective function is the electricity consumption per 100 km of the vehicle in the New European Driving Cycle(NEDC)working condition.The simulation results show that before and after optimization,the electricity consumption per 100 km in the NEDC working condition is reduced by 2.4%,and the electricity consumption per 100 km in the Worldwide Harmonized Light Vehicles Test Procedure(WLTP)working condition is reduced by 2.5%.
