The invention relates to the field of power arrangement of vehicles, in particular to a dual-mode electric drive system and a vehicle. A first motor and a second motor in the dual-mode electric driving system are connected to an output end through a gear transmission structure, and a clutch is arranged between the first motor or the second motor and the output end so that the first motor or the second motor can be selectively connected into the dual-mode electric driving system. When a vehicle is in a working condition with relatively low power demand, one motor can be disconnected from the dual-mode electric driving system by using the clutch, and only one motor is used for driving, so that the motor is conveniently maintained at relatively high output power, and the problem that in a dual-motor electric driving system in the prior art, the power consumption of the dual-mode electric driving system is reduced is solved. The problems that the output power of a single motor is small due to the fact that both the two motors output power, and the efficiency of the two motors is reduced due to the small output power when the vehicle is in the working condition with the small power requirement are solved.
本发明涉及车辆的动力布置领域,尤其涉及一种双模式电驱动系统及车辆。双模式电驱动系统中第一电机和第二电机通过齿轮传动结构连接至输出端,所述第一电机或第二电机与输出端之间设置有离合器以使第一电机或第二电机选择性的接入该双模式电驱动系统。当车辆处于功率需求较小的工况时,可以使用离合器将其中的一个电机与该双模式电驱动系统断开,仅使用一个电机进行驱动,进而便于将该电机维持在相对较大的输出功率下,进而解决了现有技术中双电机电驱动系统中,两个电机均进行动力输出导致单个电机的输出功率小,在车辆处于功率需求较小的工况时,两个电机由于输出功率小使得电机效率降低的问题。
