The invention provides a road noise absorption method and system and an automobile. The road noise absorption method comprises the steps that the vibration frequency output by a vibration sensor is obtained; acquiring a vibration absorption frequency adjusting mode of the vibration absorber; determining a target position of the mass block according to the vibration frequency and the vibration absorption frequency adjustment mode; a frequency adjusting instruction corresponding to the target position is output to the vibration absorber, and the frequency adjusting instruction is used for controlling the vibration absorber to adjust the mass block to the target position according to the vibration absorption frequency adjusting mode so as to absorb the road noise of the vibration frequency. The vibration frequency of vehicle vibration caused by road excitation and the vibration absorption frequency adjustment mode of the vibration absorber are detected, and the target position of the mass block is determined according to the vibration frequency and the vibration absorption frequency adjustment mode, so that the adjustment process of the vibration absorber is comprehensively considered in the adjustment process of the vibration absorption frequency of the vibration absorber, and the adjustment accuracy of the vibration absorber is improved. And the vibration absorption effect of the vibration absorber is better.

    本发明提供了一种路面噪音吸收方法、系统及汽车,该路面噪音吸收方法包括:获取振动传感器输出的振动频率;获取吸振器的吸振频率调节方式;根据振动频率和吸振频率调节方式确定质量块的目标位置;输出目标位置对应的频率调节指令至吸振器,频率调节指令用于控制吸振器按照吸振频率调节方式质量块调节至所述目标位置,以吸收振动频率的路面噪音。在本发明中通过检测路面激励引起车辆振动的振动频率以及吸振器的吸振频率调节方式,并根据该振动频率和吸振频率调节方式确定质量块的目标位置,从而吸振器的吸振频率进行调节过程中,综合考虑吸振器的调节过程,使吸振器的吸振效果更佳。
