The invention provides a dual-motor torque vectoring system, a control method and an automobile. The double-motor torque vectoring system comprises a first double-row planetary mechanism having the output end connected with a left wheel, a second double-row planetary mechanism having the output end connected with a right wheel, a first motor having a rotor shaft connected with the input end of thefirst double-row planetary mechanism through a first clutch, and a second motor having a rotor shaft connected with the input end of the second double-row planetary mechanism through a second clutch;the rotor shaft of the first motor is connected with the rotor shaft of the second motor and the second clutch through a third clutch. The efficient coaxial double-motor torque vectoring system is simple in structure, mature in technology and process, high in part universalization degree, small in system control difficulty and capable of adapting to various working conditions.

    本发明提出了一种双电机扭矩矢量系统、控制方法及汽车。双电机扭矩矢量系统,包括:第一双排行星机构,输出端与左侧车轮相连;第二双排行星机构,输出端与右侧车轮连接;第一电机,转子轴通过第一离合器与所述第一双排行星机构的输入端连接;第二电机,转子轴通过第二离合器与所述第二双排行星机构的输入端连接;其中,所述第一电机的转子轴通过第三离合器与所述第二电机的转子轴以及第二离合器连接。本发明的高效同轴式双电机扭矩矢量系统结构简单、技术及工艺成熟、零部件通用化程度高、系统控制难度小,能够适应各种工况。
