摘　　要：针对插电式混合动力汽车具有电量消耗和电量保持2个阶段的特点,文章提出一种基于转矩分配的模糊控制策略。在Matlab/Simulink环境下建立整车模型,并对提出的控制策略在不同行驶工况下进行仿真。结果表明,在已知路况里程的前提下,能使得电量消耗续驶里程尽量接近总行驶里程,发动机工作在高效区域,并且具有较好的燃油经济性。The operation mode of plug-in hybrid electric vehicle can be separated into two segments, namely charging depleting mode and charging sustaining mode. On this basis, a fuzzy logic control strategy is put forward based on torque distribution. The vehicle model is established under the Mat- lab/Simulink environment to evaluate the proposed control strategy under different driving scenario. The simulation results indicate that under the premise that the road condition and mileage are known, the vehicle charging depleting range can approach the total driving range and also ensure the engine operating in the high efficiency region to get better fuel economy.
