The invention provides an atmosphere lamp control method and an atmosphere lamp control system for a vehicle, and relates to the technical field of vehicle atmosphere lamps. According to the method, the audio digital signal of the vehicle-mounted entertainment system is periodically acquired, the audio digital signal is converted into the frequency domain signal, then the plurality of preset frequency bands are extracted from the frequency domain signal, the decibel value corresponding to each preset frequency band is acquired, and then the decibel value corresponding to each preset frequency band is adjusted by using the adjustment parameter, so that the decibel value of the vehicle-mounted entertainment system is adjusted. And finally, adjusting the brightness of a plurality of lamp beads of each atmosphere lamp according to the adjusted decibel values of the plurality of preset frequency bands. According to the technical scheme, each preset frequency band is adjusted by adjusting the parameters, that is, the relative relationship among the multiple preset frequency bands is reasonably adjusted, so that the difference among the multiple preset frequency bands is expanded, the change amplitude of the brightness of the atmosphere lamp can be matched with the constantly changing audio, and the immersion of a user can be improved.

    本发明提供了一种用于车辆的氛围灯控制方法及氛围灯控制系统,涉及车辆氛围灯技术领域。本发明先周期性地获取车载娱乐系统的音频数字信号,并将音频数字信号转换为频域信号,之后从频域信号中提取多个预设频段,并获取与每个预设频段对应的分贝值,然后利用调整参数对每个预设频段对应的分贝值进行调整,以获得对应的调整后的分贝值,最后根据多个预设频段的调整后的分贝值对每个氛围灯的多个灯珠的亮度进行调节。上述技术方案通过调整参数对每个预设频段进行调整,也就是合理调整多个预设频段之间的相对关系,从而拉开多个预设频段之间的差距,使得氛围灯亮度的变化幅度能够与不断变化的音频相匹配,从而可以提高用户的沉浸感。
