摘　　要：以4×2型氢燃料电池重卡为研究对象,针对其动力系统的能量管理策略展开研究。首先,提出一种基于模糊控制的氢燃料电池重卡动力系统控制策略;然后,对常用的功率跟随型控制策略和模糊控制策略进行理论分析与设计;最后,利用AVL-Cruise软件建立整车模型和能量管理策略模型,并联合Simulink与MATLAB软件进行仿真,通过城市UDC工况、六工况和40 km/h等速工况进行仿真计算,对比验证2种控制策略的经济性。结果表明:模糊控制能量管理策略相较功率跟随式能量控制策略经济性有明显提高,能量分配更为合理,为后续进一步对燃料电池汽车的动力系统优化提供了参考。Taking the 4×2 hydrogen fuel cell heavy truck as the research object,the energy management strategy of its power system of was studied.Firstly,a control strategy of hydrogen fuel cell heavy truck power system based on fuzzy control is proposed;Then,the power following control strategy and fuzzy control strategy are analyzed and designed;Finally,AVL Cruise software is used to establish the vehicle model and energy management strategy model,and Simulink and MATLAB software are combined for simulation.The simulation calculation is carried out through urban UDC working condition,six working conditions and 40 km/h constant speed working condition,so as to compare and verify the economy of the two control strategies.The results show that the economy of the fuzzy control energy management strategy is significantly improved compared with the power following energy control strategy,and the energy distribution is more reasonable,which provides a reference for further optimization of the power system of fuel cell vehicles.
