The invention provides an intelligent warning control method and system for whistling outside a vehicle, and the method comprises the steps: obtaining an audio signal outside the vehicle, carrying out the audio feature recognition of the audio signal outside the vehicle, and extracting a whistling audio; spectrogram feature processing is conducted on the whistling audio, feature parameters of the whistling audio are obtained, and the distance between the whistling vehicle and the vehicle and the whistling early warning level are determined according to the feature parameters of the whistling audio; and according to the distance and the whistling early warning level, determining to generate a safety early warning signal, and controlling a vehicle machine system of the vehicle to carry out early warning according to the safety early warning signal so as to prompt a driver of the vehicle. According to the method, danger warning for the driver in the vehicle is achieved, the safety risk that the driver cannot find dangerous conditions in time due to the fact that the volume in the vehicle is too large and whistles outside the vehicle are covered is avoided, and the vehicle driving safety is improved.

    本发明提供一种车外鸣笛智能警示控制方法和系统,其中,该方法包括:获取本车车外音频信号,并对所述车外音频信号进行音频特征识别,提取鸣笛音频;对所述鸣笛音频进行语谱图特征处理,获得所述鸣笛音频的特征参数,根据所述鸣笛音频的特征参数确定鸣笛车辆与本车的距离和鸣笛预警等级;根据所述距离和鸣笛预警等级确定生成安全预警信号,并控制本车的车机系统根据所述安全预警信号进行预警,以提示本车驾驶员。该方法实现了对车内驾驶员的危险警示,避免了车内音量过大而覆盖车外鸣笛声导致驾驶员无法及时发现危险情况的安全风险,提高了车辆驾驶安全性。
