摘　　要：混合动力汽车的发动机与电动机之间的动力切换由行驶车速控制，设计模糊逻辑控制策略，以油门踏板开度和蓄电池荷电状态（SOC值）判定转换车速值。基于ADVISOR仿真分析动力切换车速值对汽车经济性和动力性的影响。通过模糊控制，在满足驾驶员对汽车动力性需求的前提下，尽可能提高汽车的经济性和排放性。The power switch between the engine and motor of the hybrid electric vehicle is controlled by the vehicle speed. Design the power switching fuzzy control strategy with its throttle position and the battery＇ s SOC state to determine the power switching speed. Research on simulation of the power switching speed for the vehicle＇ s fuel economy and power based on ADVISOR. The simulation results show that the fuzzy torque control can properly distribute the torque between engine and motor. Use the fuzzy control can improve the fuel economy and the emission performance of the vehicle in the case of meeting the driver＇ s dynamic performance requirements.
