The invention discloses an early warning method and device for the rear distance of a vehicle, electronic equipment and a reading and storing medium. The method comprises the steps that the orientation and the distance of a following vehicle relative to a target vehicle are obtained; if the following vehicle is right behind the target vehicle, whether the vehicle distance is smaller than an emergency braking safety early warning distance or not is judged according to the braking distance of the two vehicles; if the following vehicle is behind the side of the target vehicle, whether the vehicle distance is smaller than a lane changing safety early warning distance or not is judged according to the vehicle speeds of the two vehicles; when the vehicle distance is smaller than the emergency braking safety early warning distance or the lane changing safety early warning distance, early warning is started, and a driver can be assisted to accurately judge whether emergency braking or lane changing is conducted or not according to the detected orientation and distance of the following vehicle behind and the orientation and distance between the following vehicle and the driver under the extreme weather condition; and the alarm prompt is started according to the orientation and distance of the following vehicle, so that the occurrence of safety accidents in the driving process is effectively avoided.

    本发明公开了一种车辆后车距预警方法、装置、电子设备及读存介质,获取跟车车辆相对目标车辆的方位和车距;若跟车车辆在目标车辆正后方,则根据两车的制动距离判断所述车距是否小于紧急制动安全预警距离;若跟车车辆在目标车辆侧后方,则根据两车的车速判断所述车距是否小于变道安全预警距离;当车距小于紧急制动安全预警距离或变道安全预警距离时,开启预警,能够在极端天气情况下,根据探测到的后方跟车车辆的方位和距离,并根据与跟车车辆之间的方位和距离,辅助驾驶员准确判断是否紧急制动或变道,并且通过跟车车辆的方位和距离开启报警提示,有效的避免了驾驶过程中安全事故的发生。
