Problems solved by technology

[0002] Since the dual-clutch actuators are subject to the control of external suppliers, the shift time of domestic dual-clutch transmissions is relatively long
During the driving process, it is easy for the driver to feel power interruption, causing the driver a bad driving experience of unstable acceleration
At the same time, since the motor of the 7DCTH plug-in hybrid power system is in the even-numbered gear of the transmission, the gear shifting of the motor is equivalent to the gear shifting of the AMT automatic transmission, and the power interruption will be obvious when the motor torque is large.

Abstract

The invention relates to the field of vehicle control, in particular to a method and a system for compensating gear shifting torque of a hybrid system. The method and system are applied to an engine upshift process and a motor gear shifting process, and torque stability and acceleration stability of the wheel end of a vehicle can be guaranteed by means of mutual compensation of the torque betweenthe engine and the motor.

Description

technical field [0001] The invention relates to the field of vehicle control, in particular to a shift torque compensation method and system for a hybrid system. Background technique [0002] Since the dual-clutch actuator is subject to the control of an external supplier, the shift time of the domestic dual-clutch transmission is relatively long. During the driving process, it is easy for the driver to feel the power interruption, which will cause the driver a bad driving experience of unstable acceleration. At the same time, since the motor of the 7DCTH plug-in hybrid power system is in the even-numbered gear of the transmission, the gear shifting of the motor is equivalent to the gear shifting of the AMT automatic transmission, which will cause obvious power interruption when the motor torque is large. Contents of the invention [0003] Aiming at the defects of the prior art, the present invention provides a shift torque compensation method and system for a hybrid syst...
