Abstract: The present disclosure provides a method and system for determining a pure electric available power and a vehicle, the method being applied to a vehicle including a fuel cell, the vehicle further including a battery pack and a motor, the fuel cell and the battery pack being electrically connected to the motor, wherein the method includes: monitoring a current travelling state of the vehicle and a current on-off state of the fuel cell; acquiring a maximum peak power outputted by the motor, a maximum output power of the battery pack and a starting-up power of the fuel cell; and according to the current travelling state, the current on-off state of the fuel cell, the maximum peak power, the maximum output power and the starting-up power, determining the pure electric available power. The present disclosure may quickly determine the pure electric available power, without complicated logical operation, and the operation states of the vehicle, the fuel cell system, the motor and the battery pack are taken into consideration at a same time, whereby the determined pure electric available power is closer to the actual available power.

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.
