基于用户接受度的增程式混合动力汽车控制策略研究

Strategy of Extended Range Electric Vehicle Based on User’s Approval

介绍了一种能够克服电池低能量密度瓶颈的增程式混合动力电动汽车(EREV)控制策略。同时,在基于欧洲法规和真实的长距离路面工况下,进行了3种控制策略的仿真,以此来确定EREV最能被用户接受的控制策略。通过比较各控制策略下整车的CO2排放、价格、NVH性能以及行驶里程,可以看出最优的控制策略不仅应重视改善燃油经济性,更需要重视改善用户的使用性能。

Operation strategies are presented for an extended range electric vehicle（EREV）,which is a solution to overcome low energy density limitation of batteries. Based on European legislation and a real long distance trip,simulation analyses have been done to determine which strategy is the most acceptable one for an EREV. Three strategies are analyzed in the paper. By comparing CO2 emissions,cost, NVH and driving range,the optimized operation strategy will not only focus on improving the fuel consumption but also on improving the customer usability.
