The invention belongs to the technical field of vehicles, and discloses a vehicle noise optimization method and device, equipment and a storage medium. The method comprises the following steps: acquiring modals of all noise related parts of a vehicle; when the modal difference value of each noise-related part is greater than the modal frequency-avoiding limit, acquiring a motor noise value of the vehicle; when the motor noise value is greater than the motor noise threshold value, detecting a reference torque distribution proportion corresponding to the minimum motor noise under each road condition; performing noise optimization on the vehicle based on the reference torque distribution proportion; according to the method, frequency avoiding is carried out on motor noise related part modals in the whole vehicle development and design stage; in the vehicle adjustment stage, torque distribution and adjustment are carried out based on the vehicle model, the noise in the vehicle under the starting working condition is effectively reduced, parts do not need to be changed in the vehicle model real object stage, the cost for solving the electric vehicle starting motor noise problem is reduced, meanwhile, the efficiency is improved, the motor starting noise is optimized, the use experience of a user is improved, and the customer satisfaction degree is improved.

    本发明属于车辆技术领域,公开了一种车辆噪声优化方法、装置、设备及存储介质;该方法包括:获取车辆各个噪声关联零部件的模态;在各个噪声关联零部件的模态差值大于模态避频限制时,获取车辆的电机噪声值;在电机噪声值大于电机噪声阈值时,检测各个路况下的最小电机噪声对应的参考扭矩分配比例;基于参考扭矩分配比例对车辆进行噪声优化;本发明通过在整车开发设计阶段对电机噪声关联零部件模态进行避频;在车辆调校阶段,基于车型进行扭矩分配和调整,有效降低起步工况车内噪声,不需要在车型实物阶段进行零部件设变,降低电动车起步电机噪声问题解决成本,同时提升效率优化电机起步噪声,提升用户使用体验,提高客户满意度。
