| description | The invention relates to the technical field of engine control, in particular to an engine control method and system, a medium, a controller and a vehicle. When the target excess air coefficient changes, whether the engine output torque step can be caused by responding to the change of the target excess air coefficient or not is judged; if the target excess air coefficient change is responded, the engine output torque step cannot be caused, the target excess air coefficient change is allowed to be responded, and the engine is coordinated to change the current excess air coefficient. Different from an existing engine control method with engine performance optimization as the target, the method can effectively solve the step problem generated by the output torque of the engine when the current excess air coefficient change is coordinated, has better market prospects, and is easy to operate and implement.
