摘　　要：文章以插电式混合动力汽车(plug-in hybrid electric vehicle,PHEV)为研究对象,以提高整车燃油经济性和排放性能为目标,设计了能够实现需求转矩在发动机和驱动电机之间合理分配的模糊逻辑控制策略。该模糊控制策略以SOC参考轨迹作为切入点,最大程度地发挥动力电池的存储能量。仿真结果表明,该模糊控制策略能够较好地优化发动机工作区间,提高燃油经济性和排放性能,并且能使动力电池SOC保持在设定的参考轨迹附近波动。In order to improve the fuel economy and emission performance of the plug‐in hybrid electric vehicle（PHEV） ,a fuzzy logic control strategy is designed which can realize the reasonable distribution of demand torque between the engine and the motor .In the fuzzy control strategy ,the SOC reference trajectory is chosen as the breakthrough point so as to maximize the energy storage of battery .The simulation results show that with the fuzzy control strategy ,the engine working range can be opti‐mized ,the fuel economy and emission performance improved ,and the SOC of the battery can be made fluctuate around the reference trajectory predetermined .
