摘　　要：本文以搭载两挡AMT(Automated Mechanical Transmission)的微型纯电动货车为研究对象,首先,根据货车的使用特点,进行了动力性换挡规律设计。为提高整车经济性,采取动态规划方法获取最优换挡策略,并提取可用于实车的双参数经济性换挡规律。最后在前向整车仿真模型中对两种换挡规律在NEDC80工况和日本10-15工况下进行了仿真比较。结果表明,提取的经济性换挡规律可在满足动力性能要求下提高了整车的经济性。This paper took a Pure Electric Carrier Vehicle equipped with 2-speed AMT as the research object,studied the dynamic shifting schedule according to the use characteristics of logistic vehicle firstly.In order to improve the energy economy of the vehicle,dynamic programming method is adopted to obtain the optimal shifting map,and a two-parameter economic shifting schedule is extracted from map for the real vehicle.Compared with this two dynamic shifting schedule in two driving cycle nedc80 and JPN10-15 in a forward Simulink model.The results shows that the two-parameter economic shifting schedule can meet the performance requirements and improve the energy consumption economy.
