The invention discloses a double-planet-row hybrid power system and an auxiliary braking method thereof. The double-planet-row hybrid power system comprises an engine, a driving motor, a first planetrow and a second planet row, wherein the engine is connected with a first transmission assembly used for performing power transmission, the first transmission assembly is connected with the first planet row, the driving motor is connected with a second transmission assembly for power transmission, the second transmission assembly is connected with the second planet row, the first transmission assembly is provided with a first locking device for power locking, the first planet row and the second planet row are both connected with an output assembly used for whole vehicle driving, the first planet row is connected with a third transmission assembly, the third transmission assembly is connected with a generator, and a second locking device for locking the generator is arranged on the third transmission assembly. The double-planet-row hybrid power system is advantaged in that braking energy efficiency of the whole vehicle is improved, use of friction plates of a main brake of the vehicle is reduced, the auxiliary braking effect of other vehicle accessories such as an engine and a driving motor is improved, and oil consumption cost of the vehicle is reduced.

    本发明公开了一种双行星排混合动力系统及其辅助制动方法,其包括发动机、驱动电机、第一行星排及第二行星排,其中:发动机连接有一用于动力传输的第一传动组件,第一传动组件与第一行星排相连接;驱动电机连接有一用于动力传输的第二传动组件,第二传动组件与第二行星排相连接;第一传动组件上设有用于动力锁止的第一锁止器;第一行星排与第二行星排均与用于整车驱动的输出组件相连接;第一行星排连接有第三传动组件,第三传动组件连接有一发电机;第三传动组件上设有用于发电机锁止的第二锁止器;本发明提高了整车制动能量效率,减少车辆主制动器摩擦片的使用,提高了利用发动机、驱动电机等其他车辆配件进行辅助制动效果,降低了车辆油耗成本。
