The invention discloses an automobile anti-collision early warning method and system and a storage medium. The method comprises the steps: if a rear vehicle is detected to be exist, measuring the vehicle-to-vehicle distance between the rear vehicle and the vehicle; if the vehicle-to-vehicle distance is within a preset vehicle-to-vehicle distance threshold, calculating the collision time of the rear vehicle and the vehicle according to the vehicle-to-vehicle distance; and if the collision time is less than a preset time threshold, sending an alarm signal. According to the invention, if the rearvehicle is detected, the vehicle-to-vehicle distance between the vehicle and the rear vehicle is measured, the collision time is calculated according to the vehicle-to-vehicle distance, and if the collision time is less than the preset time threshold, the alarm signal is sent out to prompt a driver that the rear vehicle has rear-end collision threatening, so that the driver can take correspondingprevention measures. Therefore, the safety of the driving process is improved.
本发明公开了一种汽车防撞预警方法、系统及存储介质。方法包括:若检测后方车辆存在,测量所述后方车辆与本车辆的车间距离;若所述车间距离位于预设车间距离阈值内,根据所述车间距离计算所述后方车辆和本车辆的碰撞时间;若所述碰撞时间小于预设的时间阈值,发出报警信号。本发明通过若检测存在后方车辆时,测量本车辆与后方车辆的车间距离,并根据车间距离计算出碰撞时间,若碰撞时间小于预设的时间阈值,发出报警信号,以提示驾驶员后方车辆存在追尾的威胁性,以便于驾驶员做出对应的防范措施,从而提高驾驶过程的安全性。
