Hybrid power assembly having four-wheel drive characteristics and vehicle assembled with same

Abstract

The invention discloses a hybrid power assembly having four-wheel drive characteristics and a vehicle assembled with the same. The power assembly comprises a first power driven system, a second power driven system and a vehicle integrated control unit, wherein the first power driven system comprises an engine, an engine electric control unit and a first gear shifting mechanism; the input end of the first gear shifting mechanism is connected with the engine through a clutch and the output end of the first gear shifting mechanism is connected with a vehicle front wheel; the second power driven system comprises a power battery stack, a management system of the power battery stack, a main motor system, and a second gear shifting mechanism; the input end and the output end of the main motor system are connected with the power battery stack and the second gear shifting mechanism respectively; the second gear shifting mechanism is connected with a vehicle back wheel; and the electric control unit of each component is connected with the vehicle integrated control unit through a bus. In the hybrid power assembly and the vehicle assembled with the hybrid power assembly, the vehicle integrated control unit is used for distributing vehicle power, which realizes not only the drive between a front axle and a back axle, but also the biaxial four-wheel drive; besides, the power assembly has the advantages of no direct mechanical coupling at the front and the back drive parts, high reliability, and easy implementation.

Description

technical field [0001] The present invention relates to the field of hybrid electric vehicles, in particular to a hybrid power assembly with four-wheel drive features and a vehicle equipped with the assembly. Background technique [0002] In recent years, the research on the vehicle power drive system that can replace the internal combustion engine has attracted more and more attention worldwide. Among many technical solutions, the electric drive system has become the most efficient due to its high efficiency, energy independent of fuel, and "zero emissions". Competitive technology; and hybrid electric vehicle has attracted more and more attention because of its low emission advantages of electric vehicles and high specific energy advantages of internal combustion engine vehicles, and has become one of the new vehicles that are competing to be developed. [0003] The application number is 200610105106.3, and the invention title is "a power system of a rechargeable hybrid ele...
