Problems solved by technology

However, since all the power passes through the generator and the motor, the motor has high power requirements, large volume and heavy weight.
At the same time, because the energy transmission process undergoes two electromechanical and electromechanical conversions, the efficiency of the entire system is low.

Description

technical field [0001] The invention relates to the technical field of hybrid electric vehicles, in particular to a dual-planetary hybrid coupling mechanism and a motor vehicle. Background technique [0002] The powertrain consists of the engine (internal combustion engine) and a drive train consisting of a transmission, differential and drive shaft. Its function is to provide the vehicle with the driving power required to drive the wheels. Internal combustion engines have a range of speeds and torques, and they work best within a small range where either fuel consumption is minimized, harmful emissions are minimized, or both. However, the actual road conditions are ever-changing, not only in the speed of the driving wheels, but also in the torque required by the driving wheels. Therefore, it is the primary task of the transmission to realize the optimal speed and torque of the internal combustion engine, that is, the optimal state of power, and a good match with the power...
