Abstract: A method for controlling an interference torque for a vehicle is provided. The method 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.

Abstract: A turbo lag boost compensation method is provided, including: calculate a theoretically required boost torque Ts; compare the theoretically required boost torque Ts with the maximum output torque Tpmax of a P2 motor; when Ts≥Tpmax, a required output boost torque Ts′ is equal to Tpmax; when Ts
