The invention discloses a safe driving aid system and method utilizing environmental noise, equipment and a storable medium. According to the safe driving aid system and method utilizing environmentalnoise, the equipment and the storable medium invention, environmental noise is converted into a spectrogram; different features in the spectrogram are extracted through different learning models, wherein the features comprise sound pressure change features and frequency change features; the sound pressure change features are used for representing the relative speeds of vehicles in a blind area and a driving vehicle; the frequency change features are used for representing the types of the vehicles (cars, trucks and the like) in the blind area; the sound pressure change features and the frequency change features are compared with features extracted from historical data, and the distance between the vehicles in the blind area and the driving vehicles is judged, so that a driver is reminded,and whether lane changing is suitable or not is selected according to the feedback distance.
本发明公开了一种利用环境噪声安全行驶辅助系统、方法、设备以及可存储介质,本发明将环境噪声转换成语谱图,通过不同的学习模型进行提取语谱图中不同的特征,其中包括声压变化特征、频率变化特征,用声压变化特征表征盲区内车辆与驾驶车辆的相对速度,用频率变化特征表征盲区内车辆的类型(轿车、货车等),将声压变化特征、频率变化特征与历史数据中提取的特征进行比对,判断盲区中车辆与驾驶车辆的远近,从而提醒驾驶员,根据反馈的远近距离选择是否适合变道。
