Hybrid driving system and vehicle including same

Abstract

The invention relates to a hybrid driving system, which comprises an internal-combustion engine, a first motor, a second motor, a power output shaft used for outputting power, a first brake, a second brake, a first transmission mechanism, and a second transmission mechanism. Two connected transmission mechanisms and brakes are arranged in the hybrid driving system. When the two brakes respectively brake, the two transmission mechanisms are in two different connection modes, namely two different transmission ratios (tap positions) are formed, therefore various working modes and corresponding tap positions can be selected according to different driving conditions of a vehicle, and driving requirements of the vehicle under different working conditions can be met further. Besides, by the adoption of the hybrid driving system provided by the invention, the low-speed torsion of the whole vehicle can be increased and the starting is quickened, moreover, the highest efficiency of the internal-combustion engine can be exerted under a high-speed condition, thereby promoting energy conversion efficiency, reducing tail gas emission and energy loss, and finally achieving the effects of low emission, low fuel consumption and high kinetic energy of the whole vehicle.

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, ...
