摘要
该文以能量流分配较复杂的插电式混合动力汽车(PHEV)为研究对象,设计出了一种以理想的SOC下降线为基础的模糊控制策略使汽车的需求转矩在发动机和电机之间合理分配,在满足汽车动力性的前提下,提高整车的燃油经济性和尾气排放性能。该策略尽可能地使用动力电池的电能,从整体上能够接近全局优化且能实时控制整车。仿真的结果与传统插电式混合动力的CD-CS策略对比,从结果来看排放性能和燃油经济性有了较大的提高。
In this paper,energy distribution more complex of the plug-in hybrid electric vehicle（PHEV） as the object of study.Authors design a fuzzy control strategy based on the ideal SOC decline line which can make the rational allocation of torque between the engine and the motor.Under premising vehicle power,improved fuel economy and emissions performance of the vehicle. The strategy use battery power as much as possible,as a whole can be close to the global optimal results and control the vehicle in time. The simulation results compare with the PHEV traditional strategy of charge cepleting（CD）-charge sustaining（CS）,the emission performance and the fuel economy has been greatly improved.
