The invention provides a dual-motor driving system and a vehicle with the same. The dual-motor drive system includes: a first drive motor having a first output shaft; the second driving motor is provided with a second output shaft; the differential mechanism is provided with a differential mechanism gear, a first half shaft and a second half shaft; the first half shaft is selectively connected with the first output shaft through a first transmission mechanism, the second half shaft is connected with the second output shaft through a second transmission mechanism, and the differential gear is selectively connected with the first output shaft through a third transmission mechanism, so that the dual-motor driving system at least comprises a first driving mode and a second driving mode. According to the technical scheme, two driving modes of single-motor integrated driving and double-motor distributed driving are achieved, the advantages of being easy to arrange, simple in structure and capable of achieving large-speed-ratio design are achieved, the scheme integrates the integrated arrangement mode and the distributed arrangement mode, the economical efficiency of the whole vehicle is met, meanwhile, the dynamic property and the controllability of the whole vehicle are improved, and the driving efficiency of the whole vehicle is improved. And the driving experience of the user is improved.

    本发明提供了一种双电机驱动系统及具有其的车辆。双电机驱动系统包括:具有第一输出轴的第一驱动电机;具有第二输出轴的第二驱动电机;具有差速器齿轮、第一半轴和第二半轴的差速器;第一半轴通过第一传动机构可选择地与第一输出轴连接,第二半轴通过第二传动机构与第二输出轴连接,差速器齿轮通过第三传动机构可选择地与第一输出轴连接,以使双电机驱动系统至少包括第一驱动模式和第二驱动模式。应用本发明的技术方案,具有单电机集成式驱动和双电机分布式驱动两种驱动模式,具有易于布置、结构简单和可实现大速比设计的特点,本方案集成了集成式和分布式的布置方式,在满足整车经济性的同时,提升整车动力性和操控性,提升用户的驾车体验。
