The device has the advantages of compact structure, effectivity, energy conservation and the like.

Description

technical field [0001] The invention belongs to the technical field of automobiles, and relates to a hybrid driving device, in particular to a dual-clutch hybrid hybrid driving device. Background technique [0002] With the increasing awareness of environmental protection and the increasing shortage of non-renewable resources such as petroleum, many car manufacturers are paying more and more attention to the research and development of energy-saving and emission-reducing models, and various hybrid vehicles are gradually coming out. Hybrid electric vehicles can meet the needs of energy and environmental protection to the greatest extent, so they have more market prospects. Currently developed hybrid electric vehicle powertrain configurations are series, parallel and hybrid three types. The series type has simple structure and easy control, but low efficiency and high cost. The parallel type is generally used for mildly mixed A-class passenger cars or below; for B-class and ...
