摘要:【中文】本发明涉及降噪技术领域,特别涉及车辆道路噪声的降噪方法、系统和实现该方法的计算机设备和计算机可读存储介质。按照本发明一个方面的车辆道路噪声的降噪方法包含下列步骤:采集并存储不同路况的道路噪声信号;采集并识别处理道路的路况信息,将经识别处理的路况信息作为参考信号;基于所述参考信号和所述道路噪声信号,确定在当前路况下的与所述道路噪声信号反相的噪声控制信号;以及以声波的方式发射所述噪声控制信号以抵消当前路况的道路噪声信号。 【EN】The present invention relates to the field of noise reduction technologies, and in particular, to a method and a system for reducing noise of vehicle road noise, and a computer device and a computer-readable storage medium for implementing the method. A method for reducing noise of a road noise of a vehicle according to an aspect of the present invention comprises the steps of: collecting and storing road noise signals of different road conditions; collecting and identifying road condition information of a road, and taking the identified road condition information as a reference signal; determining a noise control signal in phase opposition to the road noise signal under the current road condition based on the reference signal and the road noise signal; and transmitting the noise control signal in a sound wave mode to offset the road noise signal of the current road condition.
