基于模糊控制的PHEV转矩管理策略

A Torque Management Strategy for a Parallel Hybrid Vehicle Based on Fuzzy Logic Control

针对并联型混合动力汽车提出了一种基于模糊逻辑控制方法的转矩管理策略,可对发动机和电动机的输出转矩进行实时分配,并保证在整个运行路段中电池电量的平衡。通过在Advisor软件的US06路段上进行仿真测试,结果表明设计的控制器可以在一定程度上提高混合动力汽车的燃油经济性,同时降低各类污染物的排放量。

This paper presents a torque management strategy for a parallel hybrid vehicle based on fuzzylogic control. The proposed stratery assesses the amount of engine and motor＇s torque output and ensurebetter battery＇s charge balance during the driving cycle. Finally, simulation test is provided by Advisor onthe the driving cycle of US06 to evaluate the proposed stratery. The result shows that significant improve-ment of fuel economy could be achieved with polution emission reduction.
