Abstract

The invention provides a hybrid power driven system. The hybrid power driven system comprises an internal-combustion engine, a first motor and a second motor, wherein the hybrid power driven system further comprises a first clutch, a second clutch, an output shaft for outputting power, a first input shaft and a second input shaft, wherein a first transmission ratio is formed between the first input shaft and output shaft by a single-level or multi-level gear pair, and a second transmission ratio is formed between the second input shaft and the output shaft by the single-level or multi-level gear pair; the internal-combustion engine is connected to the first motor; the first motor is connected to the first input shaft by the first clutch; the second motor is connected to the second input shaft; and the first motor is further connected to the second input shaft by the second clutch. The invention further provides a vehicle comprising the hybrid power driven system. In the invention, two gears of a vehicle forward gear are arranged, so that various work modes and various corresponding gears can be flexibly selected according to different driving conditions of the vehicle; and therefore the driving needs of the vehicle in different working conditions are satisfied well.

Description

technical field [0001] The invention relates to a hybrid drive system and a vehicle including the drive system. Background technique [0002] In today's world, human beings are facing two major challenges: energy scarcity and environmental degradation. Traditional automobiles are increasingly plagued by the oil crisis. Energy conservation and environmental protection have gradually become the development theme of the automobile industry. In view of this, the call for the introduction of pure electric vehicles is increasing day by day. However, due to the constraints of many factors such as technology and policy, the current pure electric vehicles cannot be mass-produced and fully marketed. [0003] Due to its excellent performance in energy saving and environmental protection, hybrid electric vehicles are undoubtedly one of the most realistic technologies before the industrialization of pure electric vehicles. [0004] The prior art discloses a vehicle hybrid drive system, ...
