| 摘 要： | 讨论以发动机最佳燃油经济性或电动机最佳效率为控制目标的动力转换控制策略，以油门踏板位置及蓄电池SOC状态为输入变量，设计了混合动力汽车动力转换模糊控制器，建立了整车控制仿真模型。文中阐述了由电机切换到发动机工作时发动机的起动、调速控制，以及离合器快速平稳地结合的过程。仿真结果表明：对转换车速的门限值控制模糊化能够使转换车速更加符合驾驶员对动力性的要求。

| Abstract: | The control strategy on power conversion that the engine keeps on working along the optimal economy curve or the motor running in a higher efficiency is elaborated in this paper. With the throttle position and the battery＇s SOC state to determine the working state of the two power source, the power conversion fuzzy control of the super-mild hybrid electric vehicles is designed. And the overall vehicle control and simulation model is built. In the end the control of engine starting, speed regulation is discussed, which makes the quick and smooth clutch combination. |
