According to the road noise roar improvement system and method, in the vehicle running process, the back door mode is detected in real time, the back door mode is compared with a set value, and when the back door mode is larger than the set value, a back door mode formation changing module is controlled to act to change the back door mode formation, and roars in a vehicle are reduced. According to the method, the vibration mode of the back door is detected, when the mode of the back door is larger than the set value, the mode formation of the back door is changed by driving the back door mode formation changing module to generate repulsive force, the purpose of reducing roar sound is achieved, and the method has the advantages of being simple, convenient to implement and low in cost.
本发明公开了一种路噪轰鸣音改善系统及方法,车辆行驶过程中,实时检测后背门模态,将后背门模态与设定值进行比较,当后背门模态大于设定值时,控制后背门模态阵型改变模块动作改变后背门模态阵型,减小车内轰鸣音。本发明通过检测后背门的振动模态,当后背门模态大于设定值时,通过驱动后背门模态阵型改变模块产生斥力来改变后背门的模态阵形,达到减小轰鸣音的目的,该方法具有简单、实现方便,成本低的优点。
