The invention discloses a hybrid power drive speed control system and a control method. The hybrid power drive speed control system comprises an engine assembly, a first motor assembly, a second motor assembly, a gear assembly, a planet row and a power output assembly. The engine assembly is in transmission connection with the first motor assembly, the input end of the planet row is connected with an output shaft of the engine assembly, the gear assembly comprises a first gear and a second gear which are meshed with each other, the first gear is connected with the output end of the planet row, and the second gear is connected with the input end of the power output assembly and is in transmission connection with the second motor assembly. The hybrid power drive speed change system further comprises a first brake, a second brake and a clutch, and the first brake, the second brake and the clutch can be switched between a combined state and a separated state. According to the hybrid power driving speed control system, the size of the speed control system is reduced, the arrangement space is reduced, and the hybrid power driving speed control system improves the oil-saving effect of a hybrid power automobile under different working conditions and the dynamic property of the hybrid power automobile under high automobile speed and high load.

    本发明公开了一种混合动力驱动变速系统及控制方法,包括发动机组件、第一电机组件、第二电机组件、齿轮组件、行星排和动力输出组件。发动机组件与第一电机组件传动连接,行星排的输入端与发动机组件的输出轴相接,齿轮组件包括相互啮合的第一齿轮和第二齿轮,第一齿轮与行星排的输出端相接,第二齿轮与动力输出组件的输入端相接、且与第二电机组件传动连接。混合动力驱动变速系统还包括第一制动器、第二制动器以及离合器,第一制动器、第二制动器以及离合器能够在结合状态和分离状态之间切换。该系统减小了变速系统的体积、缩小了布置空间,该混合动力驱动变速系统提升了混动汽车在不同工况下的节油效果和高车速、高负荷下的动力性。
