摘　　要：针对插电式混合动力电动汽车(PHEV)运行特点,提出了PHEV最优模糊控制策略。模糊控制器将发动机的工作点控制在发动机最小燃油消耗的高效率区间内,使发动机具有较好的燃油经济性。根据路况功率需求和蓄电池SOC,调节发动机给定功率,并对能量回收不足SOC下降的情况进行改进,实现电池SOC平衡控制。将建立的模糊控制模型嵌入ADVISOR仿真软件,进行二次开发,在不同工况下进行仿真实验。结果表明:PHEV最优模糊逻辑控制具有较好的鲁棒性,在能量回收不足工况下实现电池SOC平衡,且具有较好的燃油经济性。Based on the characteristics of plug-in hybrid electric vehicle,PHEV optimal fuzzy control was proposed.The engine operating points were controlled on optimal fuel consumption curve.On the basis of the power request and SOC,the fuzzy controller could distribute the engine given power and the condition of SOC drop with insufficient of energy recovery was improved to realize constant SOC control.Furthermore,ADVISOR was developed by fuzzy control model embedding and simulated under different driving cycle.The study proved that PHEV optimal fuzzy control could realize the constant SOC control under road conditions,so that it has good robustness.
