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 idling series power generation or low-vehicle-speed series power generation in the cold region, the rotating speed of the engine can be adjusted; it is guaranteed that the suspension system is located in a good vibration isolation interval, transmission of engine excitation energy to the vehicle body side is reduced, and shaking of a steering wheel is reduced.

    本发明属于混合动力汽车整车NVH控制技术领域,公开了一种汽车方向盘抖动优化方法、装置、设备及存储介质。本发明在车辆处于怠速或低车速串联发电工况时,读取车辆的控制参数,根据环境温度确定发动机转速补偿策略,根据发动机转速补偿策略得到目标转速和目标补偿时长,调整发动机的转速,实现在车辆处于怠速或低车速串联发电工况时,通过控制参数确定发动机的目标转速和目标补偿时长,相对于混合动力车辆在寒区怠速串联发电或低车速串联发电时发动机转速不依据环境温度进行调节,悬置系统隔振性能下降,导致方向盘抖动,本发明能够对发动机的转速进行调整,保证悬置系统处于较好的隔振区间,降低发动机激励能量向车身侧的传递,降低方向盘的抖动。
