The embodiment of the invention discloses a vehicle collision early warning method and device, electronic equipment and a storage medium. The method comprises the following steps: acquiring a target driving distance between a current vehicle and a target vehicle; determining a driving fatigue index associated with the current vehicle, and determining a target braking distance early warning threshold value between the current vehicle and the target vehicle according to the driving fatigue index; and according to the current vehicle driving speed and the target driving distance, whether the braking distance when the current vehicle collides is smaller than a target braking distance early warning threshold value or not is determined, and vehicle collision early warning is sent to the current vehicle. By adopting the technical scheme of the embodiment of the invention, the problem of rear-end collision accidents caused by insufficient braking distance when the relative speed between the current vehicle and the target vehicle is relatively low is solved. By adopting dual detection of the image sensor and the radar detector, the accuracy of target driving distance detection is improved, so that the efficiency of vehicle collision early warning is improved, and the occurrence rate of vehicle collision is reduced.
本发明实施例公开了一种车辆碰撞预警方法、装置、电子设备及存储介质。该方法包括:获取当前车辆与目标车辆间的目标行车距离;确定与当前车辆关联的驾驶疲劳指数,并依据所述驾驶疲劳指数确定当前车辆与目标车辆间的目标制动距离预警阈值;依据当前车辆行驶速度以及目标行车距离,确定当前车辆发生碰撞时的制动距离是否小于目标制动距离预警阈值,并对当前车辆发出车辆碰撞预警。采用本发明实施例的技术方案,解决了在当前车辆与目标车辆间的相对速度较小时,由于制动距离不足导致的追尾事故发生的问题。采用图像传感器以及雷达探测器的双重检测,提高目标行车距离检测的准确性,从而提高车辆碰撞预警的效率,降低车辆碰撞的发生率。
