The invention belongs to the technical field of hybrid electric vehicle NVH control, and discloses an automobile steering wheel shaking optimization method, device and equipment and a storage medium. When the vehicle is in the idling or low-speed series power generation working condition, the control parameters of the vehicle are read, the engine rotating speed compensation strategy is determined according to the environment temperature, the target rotating speed and the target compensation duration are obtained according to the engine rotating speed compensation strategy, and the rotating speed of the engine is adjusted. The target rotating speed and the target compensation duration of the engine are determined through the control parameters, and compared with the situation that the rotating speed of the engine is not adjusted according to the environment temperature, the vibration isolation performance of a suspension system is reduced, and a steering wheel shakes when the hybrid power vehicle conducts idli
