摘　　要：基于CRUISE/Simulink软件对某款增程式混合动力车辆进行建模仿真,对三种可行的増程器能量控制策略进行对比分析。结果表明:单点控制策略具有最佳的燃油经济性,两点控制策略的等效燃油消耗量与功率跟随控制持平,较单点跟随控制策略高1%。功率跟随控制策略保证最低的能量转换损耗,两点控制策略能合理分配动力电池和増程器的能量,综合考虑整车能量利用率和动力电池使用寿命,最大程度发挥增程式混动系统的优势。In this paper,modeling and simulation of a range-extended hybrid electric vehicleis implemented with AVLCRUISE and MATLAB/Simulink,three feasible energy control strategies of APU(Auxiliary Power Unit) are compared and analyzed.The simulation results illustrate that:the single-point control strategy has the best fuel economy;the optimal operation line control strategy ensures the lowest energy conversion loss.The two-point control strategy can allocate the battery energy andAPU energy reasonably,which can comprehensively consider the energy utilization rate and battery cycle life,takes the full advantage of series range-extended hybrid system.
