Abstract

The invention relates to an engine torsion control method in the shift process of mixed power vehicle speed changer, wherein based on the driving speed and the position of acceleration pedal, the controller via preset method, calculates out the torsion needed on the output axle of speed changer, to obtain the output torsion after and before the shift. With said invention, the power transmitted to the wheels can keep stable in shift process, to reach the stability of CVT (stepless speed changer).

Description

technical field

[0001] The invention relates to an engine torque control method in the gear shifting process of a transmission of a hybrid electric vehicle, in particular to an engine torque control method in the gear shifting process of an automatic gear shifting stepped transmission of a hybrid electric vehicle. Background technique

[0002] With the increasingly prominent global environmental and energy issues, the development of new vehicles with low emissions and low fuel consumption has become the primary task of the development of the automotive industry today. Hybrid electric vehicle technology avoids the shortage of battery technology and energy infrastructure of pure electric vehicles. It is a good solution to current problems and has become a hot spot in international automotive research and development.

[0003] In a traditional car driven only by an internal combustion engine, the power of the internal combustion engine cannot be continuously transmitted to the ...
