Problems solved by technology

[0003] Existing hybrid power generally has two modes of pure electric driving and hybrid drive, such as BYD F3DM dual-mode hybrid power, which is a dual-clutch + dual-motor structure. Through reasonable matching, it can achieve better fuel economy than traditional vehicles, but its structure is complex ; In addition, there are also three-mode hybrid vehicle systems, such as the Lexus LS600hL three-mode hybrid power system, whose three-mode functions are hybrid, power and snow modes. The "hybrid" mode can run smoothly and is suitable for urban or suburban areas. Driving, the "power" mode speeds up the response of the accelerator pedal, and the "snow" mode slows down the response of the accelerator pedal, making it easy to accelerate on slippery roads, but its three-mode function is not unique to hybrids. Hybrids have the advantages of combining economy and power underutilized

Abstract

The invention provides a hybrid power system and a hybrid vehicle. The hybrid power system comprises a composite motor unit, a planet gear unit, a first clutch and a second clutch, a motor, a first brake and a second brake and a one-way clutch. The hybrid power system provided by the invention combines revolving speed coupling properties of the planet gear unit and the electromagnetic coupling properties of the composite motor unit; the combination can realize four forward driving modes, a backward driving mode and a stop charging mode, thereby increasing the fun of driving; while the fuel economy is optimized, the power output is considered; and the hybrid power system better exerts the advantages in the aspects of economy and power property.

Description

technical field [0001] The invention relates to the field of hybrid electric vehicles, in particular to a hybrid power system capable of realizing multiple driving modes and a hybrid power vehicle using the power system. Background technique [0002] Hybrid has become the focus of current automobile development. Its advantages of energy saving and emission reduction have been widely valued by automobile companies and research institutions, and they have invested heavily in research and development, and many molded products have been put on the market. In the foreseeable future, it will be promoted and used on a large scale as the mainstream direction of automobile development. [0003] Existing hybrid power generally has two modes of pure electric driving and hybrid drive, such as BYD F3DM dual-mode hybrid power, which is a dual-clutch + dual-motor structure. Through reasonable matching, it can achieve better fuel economy than traditional vehicles, but its structure is compl...
