The invention discloses a multi-mode double-planet-row hybrid power driving system. An engine and a first motor jointly drive a first planet row mechanism; the first planet row mechanism drives a second planet row mechanism through an intermediate gear; the second planet row mechanism is in transmission connection with a second motor and further drives a differential mechanism assembly, the firstplanet row serves as an engine power dividing mechanism, when fine energy flow control is matched, range-extending type power generation and vehicle driving power can be considered at the same time, and the engine is ensured to work in the optimal energy-saving rotating speed area; under multi-mode switching, the motor works in the optimal efficiency area as much as possible, the problems that anengine is serious in oil consumption during driving in an urban area, the motor is weak in acceleration during high-speed driving, the motor is serious in energy consumption and the like are effectively solved, and high practicability is achieved.
本发明公开了一种多模双行星排混合动力驱动系统,其动机和第一电机联合驱动第一行星排机构,第一行星排机构通过中间齿轮传动第二行星排机构,第二行星排机构与第二电机传动地连接并且第二行星排机构还传动差速器总成,第一行星排作为发动机功率分流机构,当配以精细的能量流控制,能同时兼顾增程式发电和车辆驱动动力,并且保证发动机工作在最佳节能转速区;电动机在多模式切换下,尽可能在最佳效率区工作,有效解决了在市区行驶发动机耗油严重、高速行驶电动机加速乏力、电动机耗能严重等问题,具有很强的实用性。
