Abstract

The invention relates to a method and device for controlling a vehicle engine, the engine, a storage medium and a vehicle. The technical problem that the overall vehicle NVH performance is influencedby severe shaking when an engine is shut down in the related technology is solved. The method for controlling the vehicle engine includes the steps of confirming that the engine is switched from an operating state to a power-off shut-down state; controlling a disc in an intake throttle valve of the engine to be closed for a preset period of time; and after the preset period of time, controlling the disc in the intake throttle valve to be reset.

Description

technical field [0001] The present disclosure relates to the field, and in particular, to a method and apparatus for controlling a vehicle engine, an engine, a storage medium, and a vehicle. Background technique [0002] In the related art, the function of the vehicle engine flywheel is to store the energy of the working stroke of the engine, and release the energy in the other three strokes, so as to make the crankshaft transmission stable. However, when the engine is turned off, due to the large inertia of the flywheel on the engine, the crankshaft continues to rotate under the inertia of the flywheel, and the engine will vibrate violently at the moment of turning off the engine, which will affect the NVH (Noise, Vibration, Harshness; noise, vibration, Acoustic roughness) performance. Contents of the invention [0003] The present disclosure provides a method and device for controlling a vehicle engine, the engine, a storage medium and a vehicle, so as to solve the tech...
