Description

technical field [0001] The invention belongs to the technical field of hybrid electric vehicles, and in particular relates to a multi-power input hybrid driving device. Background technique [0002] With the depletion of oil resources and the increasing pollution of automobiles, the world's major automobile manufacturers have invested heavily in the research and development of hybrid electric vehicles, among which plug-in hybrid is the most fuel-efficient solution other than pure electric solutions. From the perspective of power coupling, plug-in hybrid electric vehicle power drives are usually divided into three categories: parallel schemes, series schemes, and hybrid schemes. [0003] The parallel connection scheme refers to that the engine and the electric motor jointly drive the car, wherein the engine and the electric motor belong to two sets of power systems, which can provide torque to the driving wheels separately. When the vehicle is running at a medium or low spee...
