The invention belongs to the technical field of NVH (Noise Vibration and Harshness) of hybrid electric vehicles, and discloses a vehicle noise optimization method, device and equipment and a storage medium. An initial engine adjustment relation table is obtained according to engine oil consumption and emission performance, the current vehicle working condition and the vehicle speed of a vehicle are obtained, and when the vehicle speed is smaller than a noise adjustment vehicle speed threshold value, the initial engine adjustment relation table is searched according to the current vehicle working condition and the vehicle speed; a target engine adjusting strategy corresponding to the current vehicle working condition and the vehicle speed is obtained, and the target engine adjusting strategy comprises a target engine rotating speed adjusting strategy and a target engine rotating speed rising speed adjusting strategy when the generated power is kept unchanged; adjusting the rotating speed and the rotating speed rising rate of the engine according to the target engine adjusting strategy to enable the rotating speed of the engine to be in the target power generation working condition, and reducing noise of the vehicle. According to the method, on the basis of considering the vehicle charging efficiency, the engine noise in the vehicle acceleration process can be reduced in a more economical mode.
