中文摘要:
      针对一款并联混合动力轿车,分析了其结构形式下机械自动变速器的换档过程;设计制定了较为完善的电机有源同步辅助换档控制策略。使得在换档的同步过程中,电机可以主动调节变速器输入轴转速,从而实现了减小变速器输入与输出轴转速差和缩短同步时间的目的。通过对MATLAB/Simulink环境下建立的动力传动系统模型进行仿真试验以及进行实车试验,证明了该技术有效地缩短了并联混合动力轿车的换档时间,保障了同步器的寿命。
英文摘要:
      Aimed at a Parallel Hybrid electric vehicle,a strategy of electric motor active synchronistic control is put forward based on the dynamic analysis of the powertrain during the whole shifting process.The proposed control strategy enables the electric motor during shifting process through its speed control to adjust the input shaft speed of the transmission to its output shaft speed.Results from the simulation on the platform of MATLAB/Simulink based on a powertrain's dynamic model as well as results from the...
