The invention provides a dual-motor driving system, a vehicle and a control method.The dual-motor driving system comprises a first motor, a second motor and a Ravigneaux type planetary gear mechanism; wherein an output shaft of the first motor is in clutch transmission connection with a large sun gear of the Ravigneaux planetary gear mechanism, and an output shaft of the second motor is in clutch transmission connection with a small sun gear of the Ravigneaux planetary gear mechanism; a shell and a gear ring of the Ravigneaux planetary gear mechanism, the shell and a large sun gear, and the shell and a small sun gear are in clutch transmission connection respectively; a planet carrier of the Ravigneaux planetary gear mechanism is used for outputting constant torque. According to the dual-motor driving system, the vehicle and the control method, switching of different working modes can be achieved through cooperation of the clutch structures, so that constant output of torque is achieved, the power use efficiency of the driving system is effectively improved, and then the economical efficiency of the driving system is improved.

    本公开提出一种双电机驱动系统、车辆和控制方法,其中,双电机驱动系统包括:第一电机、第二电机和拉维娜式行星齿轮机构;其中,第一电机的输出轴和拉维娜式行星齿轮机构的大太阳轮为离合式传动相连,第二电机的输出轴和拉维娜式行星齿轮机构的小太阳轮为离合式传动相连;拉维娜式行星齿轮机构的壳体和齿圈之间、壳体和大太阳轮之间以及壳体和小太阳轮之间分别为离合式传动相连;拉维娜式行星齿轮机构的行星架用于输出恒定扭矩。在本公开的一种双电机驱动系统、车辆和控制方法中,利用各个离合结构的配合,能够实现不同工作模式的切换,以便于实现扭矩的恒定输出,从而有效提高驱动系统的动力使用效率,进而提高驱动系统的经济性。
