摘　　要：以某款混合动力商用车为研究对象,分析了基于规则的能量管理策略的不足,将基于规则的能量管理策略与模糊控制理论相结合,提出一种基于模糊控制的能量管理策略。设计以电池SOC和车速为输入变量,以发动机启停控制命令为输出变量的模糊控制器,控制发动机的启停。在MATLAB/Simulink软件中搭建出能量管理策略模型,在AVL Cruise软件中搭建出整车仿真模型,进行NEDC循环工况的联合仿真。仿真结果表明,基于模糊控制的能量管理策略优化能够合理分配发动机与电机的输出转矩,并能够进行合理的行车模式切换。Taking a hybrid commercial vehicle as the research object, the paper analyzes the deficiency of rulebased energy management strategy. Combining the rule-based energy management strategy with fuzzy control theory,a new energy management strategy based on fuzzy control is proposed. The fuzzy controller which takes SOC and vehicle speed as input variables and engine start and stop control command as output variable is designed to control the start and stop of engine. The energy management strategy model is built in matlab/simulink software, and the vehicle simulation model is built in AVL cruise software to perform the joint simulation of NEDC cycle conditions. The simulation results show that the optimization of energy management strategy based on fuzzy control can distribute the output torque of engine and motor reasonably and switch the driving mode reasonably.
