The invention relates to the technical field of automobiles, and discloses a three-planet-row hybrid power system, a hybrid power method and a hybrid electric vehicle. According to the three-planet-row hybrid power system, a hybrid power system which is based on configuration of three planet rows and combines two clutches, two brakes, two motors and an engine is provided through reasonable layoutof a planet row mechanical structure, and various working modes are realized through different combinations of the operating elements. According to the hybrid power method utilizing the three-planet-row hybrid power system, four pure electric drive modes, two ECVT hybrid power modes, four engine direct drive/parallel drive modes and four brake energy recovery modes are achieved through specific on-off combination of all operating elements and control over the engine and the motors, so that the system performance of a gearbox is further improved, and higher transmission efficiency is further obtained. The hybrid electric vehicle has higher transmission efficiency and more excellent hybrid power performance (dynamic property and economy).

    本发明涉及汽车技术领域,公开了一种三行星排混合动力系统、混动方法及混合动力汽车,该三行星排混合动力系统通过行星排机械结构的合理布局提供了一种基于3个行星排构型并结合两个离合器、两个制动器、两个电机和发动机的混合动力系统,并通过各操作元件的不同组合以实现多种工作模式,该利用三行星排混合动力系统的混动方法通过具体地各操作元件的启闭组合及其对发动机、电机的控制实现了四个纯电驱动模式、两个ECVT混动模式、四个发动机直驱/并联驱动模式和四个制动能量回收模式;从而进一步地提高了变速箱的系统性能,进一步获得了更高的传动效率。该混合动力汽车具有了更高的传递效率,具备了更优良的混合动力性能(动力性和经济性)。
