Title:
METHOD AND APPARATUS FOR CONTROLLING IMPACT TORQUE OF HYBRID VEHICLE
Document Type and Number:
WIPO Patent Application WO/2022/266877
Kind Code:
A1
Abstract:
A method for controlling an impact torque of a hybrid vehicle. The hybrid vehicle comprises an engine, a driving electric motor, and a clutch, which is arranged between the engine and the driving electric motor. The control method comprises: an acquisition step, which is used for acquiring the torque of an engine; and a first adjustment step, which is used for causing the torque capacity of a clutch to reduce to an impact torque capacity limit value when the torque of the engine exceeds a first torque threshold value, wherein the impact torque capacity limit value is determined on the basis of the intensity of an assembly in a torque transfer path of a hybrid vehicle. Therefore, even if an excessive impact torque occurs, an impact torque which is transferred to an assembly in a torque transfer path via a clutch can be reduced, such that the impact of the excessive impact torque on the assembly can be avoided; furthermore, the corresponding assembly of a hybrid vehicle can be prevented from cracking or breaking due to the excessive impact torque. The present application further relates to an apparatus for controlling an impact torque of a hybrid vehicle.
