According to the technical scheme, the device and method for controlling the wind vibration noise of the automobile comprise a plurality of elastic air bags, inflation equipment and a control system; the elastic air bag is arranged inside the automobile interior trimming panel; the inflation equipment is arranged between the automobile interior trim panel and an automobile shell metal plate or between the automobile interior trim panel and an automobile bottom plate. The control system is used for judging whether wind vibration noise is generated in a compartment or not according to the received vehicle state information; when the control system judges that wind vibration noise occurs in the compartment, the control system drives the inflation equipment to inflate the elastic air bags, so that the elastic air bags are increased in size and enter the compartment to reduce the internal space of the compartment. The sound cavity in the automobile is changed by changing the size of the compartment space, the appearance of the automobile is not changed while the wind vibration noise is effectively controlled, and the aerodynamic resistance during automobile running is not increased.
本发明采用的技术方案是:一种控制汽车风振噪声的装置及方法,包括若干个弹性气囊、充气设备和控制系统;所述弹性气囊设置于汽车内饰板内部;所述充气设备设置于汽车内饰板与汽车外壳钣金之间或者汽车内饰板与汽车底板之间;所述控制系统用于根据接收到的车辆状态信息判断车厢内部是否发生风振噪声;当控制系统判定车厢内部发生风振噪声,控制系统驱动充气设备向弹性气囊充气,使弹性气囊体积增大并进入车厢内部以减小车厢内部空间。本发明通过改变车厢空间大小改变车内声腔,有效控制风振噪声的同时不改变汽车外观,不增加汽车行驶时的气动阻力。
