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.
Description
technical field [0001] The present invention relates to the technical field of safe driving, and more specifically relates to an auxiliary system, method, device and storage medium for safe driving using environmental noise. Background technique [0002] Accidents of moving vehicles often occur when the vehicle changes lanes. Therefore, when the driver changes the driving lane, it is important to confirm a nearby vehicle approaching from behind the lane to change. Drivers use the rearview mirror to identify nearby vehicles approaching from behind them. However, rearview mirrors have blind spots in which nearby vehicles may not be recognized. Blind spots indicate areas that the driver of my vehicle is not aware of even if nearby vehicles are approaching me. When the driver fails to find the vehicle in the blind spot and changes lanes to the same lane, a collision accident may result. [0003] Blind spot warning systems have recently been introduced to identify vehicles in...
