The invention discloses an integrated automobile road noise active noise control method, which comprises the following steps that: 1) an IVI host acquires automobile parameter information in real time, judges whether a current condition meets an active noise reduction function or not, and transmits the active noise reduction function to an external power amplifier when the current condition meets the active noise reduction function; 2) the IVI host selects one preset noise control method according to the parameter information and transmits the noise control method to an external power amplifier for execution; (3) an external power amplifier obtains driving parameter information in real time; and 4) adjusting loudspeaker output according to the real-time vehicle parameters. According to the active road noise control method, the road noise level can be well improved, the hardware cost of the whole vehicle can be remarkably reduced through the integrated design, and the customer function experience is improved.

    本发明揭示了一种集成式汽车路噪主动噪声控制方法,包括以下步骤:1)IVI主机实时获取车辆参数信息,IVI主机判断当前条件是否满足执行主动降噪功能,当满足条件时输送主动降噪功能至外置功放;2)IVI主机根据参数信息选择预设的其中一个噪声控制方法并输送至外置功放执行;3)外置功放实时获取行车参数信息;4)根据实时车辆参数调整扬声器输出。本发明路噪主动噪声控制方法可较好改善路噪水平,集成式设计可显著降低整车硬件成本,增加客户功能体验。
