Abstract

The invention discloses a hybrid power coupling mechanism. The hybrid power coupling mechanism comprises two motors, two planetary lines, an axial gear system and the like, wherein an engine is connected with a planet carrier of the first planetary line and is connected with a sun gear of the first planetary line; a driving motor is connected with a sun gear of the second planetary line through agear pair, a planet carrier of the second planetary line is fixed, and an inner gear ring of the second planetary line is output. The invention further discloses a corresponding control system and a control method. By means of the hybrid power coupling mechanism, the control system and the control method, multiple driving mode of a pure electric mode, a hybrid power mode and the like can be achieved, only three shafts need to be arranged, the structure is compact, and requirementsfor the space are lowered.

Description

technical field [0001] The invention relates to the field of hybrid electric vehicles, in particular to a hybrid coupling mechanism, a control system and a control method. 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 state...
