摘要： The present disclosure relates to a method and an apparatus for a torque control of a hybrid vehicle, a storage medium and an electronic device. The method includes: determining a target-total-torque-change-gradient under a condition that a limitation requirement based on a gradient of torque change of a DCT is received, where the target-total-torque-change-gradient is a minimum of the gradient of torque change of the DCT and a total-torque-request-filter-gradient of a front-axle; and determining a torque request of an electric motor and an actual-torque-response-change-gradient of an engine; and determining a gradient of torque change of the electric motor according to the target-total-torque-change-gradient and the actual-torque-response-change-gradient of the engine; filtering the torque request of the electric motor according to the gradient of torque change of the electric motor. The limitation of the gradient of torque change of the DCT is considered, a problem that the actual total torque responses of the electric motor and the engine exceeds the limitation requirement of the gradient of torque change of the DCT because that the actual torque response of the engine does not meet the limitation requirement of the gradient of torque change of the engine is effectively solved, and a drivability of the whole vehicle is improved.

摘要： The present disclosure relates to the field of vehicle control technology, and provides a method and a device for controlling an interference torque for a vehicle, a controller, an equipment, a program, a medium. The method provided in the present disclosure is applied to a new energy vehicle including an electric motor and an engine, and includes steps of: arbitrating between a pedal torque of a driver and an interference torque required by ESP; performing an initial allocation on the electric motor and/or the engine in response to the pedal torque when the vehicle is in a hybrid drive mode, to meet an engine torque request while ensuring that the engine is operated at an optimal operation point; and determining, based on the initial allocation, whether the motor is capable of fully responding to the arbitrated torque, if so, controlling the motor to respond to the arbitrated torque in priority, otherwise controlling the engine and the motor to cooperatively respond to the arbitrated torque. The present disclosure, by enabling the motor to respond to ESP interference in priority, achieves the objective of enabling the vehicle to respond rapidly to the interference torque from the ESP.
