摘　　要：为了提高汽车燃油经济性和排放性能,针对并联混合动力汽车,提出了一种基于模糊控制技术的转矩协调控制策略。首先,分析并联混合动力汽车驱动系统的整体结构和转矩耦合下的运行模式,其次,利用MATLAB/Simulink工具建立系统转矩模糊控制策略,并在5次NEDC和UDDS循环工况下与ADVISOR平台进行联合仿真。结果表明,相较于电机辅助控制策略,在满足动力性能前提下,该方法进一步提升了整车燃油经济性、环保性和发动机工作性能。In order to improve the fuel economy and emission performance of automobiles,this paper proposes a torque coordination control strategy for parallel hybrid electric vehicles based on fuzzy control technology.Firstly,the overall structure of the parallel hybrid electric vehicle drive system and the operation modes under torque coupling are analyzed.Secondly,the system torque fuzzy control strategy is established by using MATLAB/Simulink tool,and its simulation is carried out with ADVISOR platform under five cycles of NEDC and UDDS.By comparison with the motor-assisted control strategy,the results indicate that,the proposed method further improves the fuel economy,environmental protection and engine performance of the whole vehicle on the premise of satisfying the dynamic performance.
