摘　　要：混合动力电动汽车的控制策略对汽车的各方面性能都起着重要作用,尤其对其燃油经济性有着极大影响。以混联式混合动力电动汽车为研究对象,对规则控制策略的工作模式进行分析,通过Cruise_Matlab在WLTC循环工况下联合仿真,对各模式切换阈值进行优化,提升其燃油经济性。仿真数据显示:油耗得到了明显降低。通过转鼓试验,验证了优化后控制策略的有效性。The control strategy of hybrid electric vehicle plays an important role in all aspects of vehicle performance,especially its fuel economy.Taking hybrid electric vehicle(HEV)as the research object,the working mode of the rule control strategy was analyzed.Cruise_Matlab cosimulation under WLTC cycle conditions was used to optimize the switching threshold of each mode to improve its fuel economy.The simulation data showed that the fuel consumption was significantly reduced.The effectiveness of the optimized control strategy was verified by the drum test.
