本发明的技术路线如下：一种基于双排行星系统的单电机混动耦合装置，包括发动机E、电机M、输出轴out、2个行星系统、2个制动器和2个离合器，行星系统A1包括太阳轮S1、行星架PC1、行星轮P1、齿圈R1，行星系统A2包括太阳轮S2、行星架PC2、行星轮P2、齿圈R2；行星系统A1的行星架PC1与行星系统A2的齿圈R2相连，行星系统A1的太阳轮S1与行星系统A2的太阳轮S2相连。
发动机E通过离合器C1与行星系统A1的行星架PC1相连、通过离合器C2与行星系统A1的太阳轮S1相连，电机M与行星系统A1的太阳轮S1相连；制动器B1与行星系统A1的齿圈R1相连，制动器B2与行星系统A2的齿圈R2相连；输出轴out与行星系统A2的行星架PC2相连，并由该输出轴驱动。
本发明相对于现有技术的优点有：结构紧凑：本发明采用双排行星系统，2个离合器及2个制动器，仅需1个电机，可显著降低成本及结构复杂度；工作模式多、传动效率高：本发明具有4种电机驱动、4种发动机驱动、4种混合驱动、4种行车发电、2种制动发电及1种停车发电模式，可适应各种复杂的工况，动力性及燃油经济性俱佳。
