The invention discloses a multi-mode hybrid variable speed driving system of an automobile and the automobile. The multi-mode hybrid variable speed driving system comprises a power supply device, a power transmission device and a power control device. The power supply device comprises an engine, a first motor and a second motor. The power transmission device includes a first planetary gear set and a second planetary gear set. The power control device comprises a brake and a clutch. In the multi-mode hybrid variable-speed driving system of the automobile, six driving modes including a power dividing mode, a traditional mode, a parallel connection mode, a single-motor pure electric mode, a double-motor pure electric mode and an energy recovery mode can be achieved by controlling closing and opening of a brake and a clutch, and the multi-mode hybrid variable-speed driving system of the automobile is achieved by switching the modes. And the phenomenon of power backflow generated when the automobile runs at a high speed in a power split mode state is avoided, so that the efficiency of the multi-mode hybrid variable-speed driving system of the automobile is improved, and the oil consumption of the system is reduced.

    本发明公开了一种汽车的多模式混动变速驱动系统及汽车,多模式混动变速驱动系统包括动力供给装置、动力传输装置以及动力控制装置。动力供给装置包括发动机、第一电机以及第二电机。动力传输装置包括第一行星齿轮组和第二行星齿轮组。动力控制装置包括制动器和离合器。在该汽车的多模式混动变速驱动系统中,可通过控制制动器和离合器的闭合与断开,实现功率分流模式、传统模式、并联模式、单电机纯电模式、双电机纯电模式、能量回收模式这六种驱动模式,并通过模式之间的切换,来避免汽车在功率分流模式状态下高速行驶时,产生功率回流的现象,从而提高汽车的多模式混动变速驱动系统的效率,降低系统油耗。
