摘　　要：为了有效的实现行星齿轮机构的动力耦合功能,分析了双动力源与单排行星齿轮机构连接方式的系统效率,提出了实现混合动力汽车多种工作模式的结构方案,建立了行星齿轮机构的动力学模型,针对启动加速这一工况,建立了电机助力的控制策略,基于matlab/simulink建立了仿真模型,基于该模型进行了加速工况动态仿真并获得了良好的控制效果。该分析有助于混合动力汽车的动力匹配与优化控制。In order to realize effectively the function of gear unit for power compound, based on the analysis of system efficiency, the scheme to integrate double power source and planet gear unit is contrived. Furthermore, the confignration of power train, which is to help realize various working mode of hybrid electric vehicle, is put forward. According to this embodiment, the mathematical model of power train and control strategy of motor/generator are also founded. Based on matlab/simulink, the acceleration process is simulated. The results show that the method is efficient for prevention of vibrations.The design scheme and control strategy can be used to guide the power matching and optimized control in hybrid electric vehicle.
