Abstract

The invention relates to a gearbox of a hybrid electric vehicle and a corresponding control method thereof. The gearbox comprises an engine, the engine is connected with a first main reducer through a first motor, the first main reducer is connected with a differential mechanism, the differential mechanism is respectively connected with a driving gear of a second main reducer and a driving gear of a third main reducer, the driving gear of the second main reducer is connected with a first planetary gear mechanism, the first planetary gear mechanism drives left wheels, the driving gear of the third main reducer is connected with a second planetary gear mechanism, and the second planetary gear mechanism drives right wheels. By using the gearbox of the hybrid electric vehicle and corresponding control method thereof disclosed by the invention, a traditional differential mechanism and a traditional planetary gear mechanism are adopted as a power coupling device for hybrid electric vehicles, and the coupling device realizes the stepless speed regulation of a vehicle, thereby greatly improving the fuel economy and the comfortableness of the whole vehicle, eliminating a traditional gearbox structure, effectively prolonging the service life of a battery, and effectively controlling the cost.

Description

technical field [0001] The present invention relates to the technical field of vehicle power devices, in particular to the technical field of power devices for hybrid electric vehicles, in particular to a gearbox for hybrid electric vehicles and a corresponding control method. Background technique [0002] Energy saving, environmental protection and safety are the three major themes in the world today. With the increase of car ownership, the environment and energy are under great pressure. Therefore, people have been actively exploring the research and development of new energy saving and environmental protection. Pure electric vehicles are the It is an ideal substitute for traditional cars, but due to technical limitations such as battery mileage and lifespan, hybrid cars are the best substitute at this stage. [0003] Hybrid electric vehicles include two or more power sources, arranged in various ways, and can be divided into serial, parallel and hybrid types from the dire...
