The invention discloses a dual-motor multi-mode driving system, a driving strategy and an automobile. The driving system comprises double motors, double speed reducers, double clutches, driven gears and a differential mechanism. The driving modes of the driving system comprise a single-motor driving mode, a dual-motor common driving mode and a single-motor driving single-tire mode. According to the dual-motor multi-mode driving system, a single motor independently drives a vehicle to run, dual motors jointly drive the vehicle to run, or the dual motors respectively drive respective corresponding tires so as to drive the vehicle; the problems that in the prior art, the number of working modes is small, motor efficiency is low, and the speed ratio expansion and development difficulty of a motor and a transmission is large due to structural limitation are solved. By selecting different driving modes, the normal running of the vehicle under various working conditions can be ensured.

    本发明公开了一种双电机多模式驱动系统、驱动策略及汽车。该驱动系统包括:双电机、双减速器、双离合器、从动齿轮和差速器;该驱动系统的驱动模式包括:单电机驱动模式、双电机共同驱动模式和单电机驱动单轮胎模式。本发明通过此双电机多模式驱动系统,实现了单电机单独驱动车辆行驶、双电机共同驱动车辆行驶或者双电机分别驱动各自对应的轮胎进而驱动车辆,解决现有技术中存在的工作模式少、电机效率低、结构限制导致电机和变速器速比拓展开发难度大等问题;通过选择不同的驱动模式,能够保证车辆在各种工况下正常行驶。
