Description

technical field [0001] The invention relates to the technical field of automobile power systems, in particular to a multi-mode hybrid power coupling device based on a three-plane row. Background technique [0002] At present, domestic and foreign hybrid systems mostly adopt three configurations: series, parallel and hybrid. Among them, the series type realizes the mechanical decoupling between the engine and the driving wheels, and the traction characteristics of the motor are close to the torque-speed characteristics, which is more suitable for heavy off-road vehicles, but due to the secondary conversion of energy, the overall efficiency is low; Although there is no secondary conversion of energy in the parallel type, because the engine and the driving wheels are mechanically coupled, the operating point of the engine is mostly fixed in a narrow speed-torque area, so the overall efficiency of the engine is still difficult to control; There are many applications in the fiel...
