The invention provides a vehicle collision early warning method, device and equipment and a storage medium, and relates to the technical field of driving assistance systems.The method comprises the steps that according to the relative distance and the relative speed between a vehicle behind a target vehicle and the target vehicle, the predicted collision duration when the vehicle behind the target vehicle collides with the target vehicle is calculated; a plurality of candidate collision risk levels are determined, each candidate collision risk level corresponds to a preset collision time threshold value, and the higher the candidate collision risk levels are, the smaller the corresponding preset collision time threshold value is; and determining a candidate collision risk level corresponding to a preset collision time threshold value which is greater than or equal to the predicted collision duration and has a minimum numerical value as a target collision risk level, and outputting collision early warning prompt information corresponding to the target collision risk level. According to the invention, multi-level collision risk early warning is realized, and the rear vehicle can visually know the degree of the current collision risk.
本申请提供一种车辆碰撞预警方法、装置、设备及存储介质,涉及驾驶辅助系统技术领域,包括:根据目标车辆后方车辆与目标车辆的相对距离、相对速度计算后方车辆碰撞上目标车辆的预测碰撞时长;确定若干个候选碰撞风险等级,每个候选碰撞风险等级对应一个预设碰撞时间阈值,候选碰撞风险等级的等级越高,对应的预设碰撞时间阈值越小;将大于或等于预测碰撞时长,且数值最小的预设碰撞时间阈值对应的候选碰撞风险等级确定为目标碰撞风险等级并输出目标碰撞风险等级对应的碰撞预警提示信息。本申请实现了多级碰撞风险预警,可以使后方车辆直观地了解到当前碰撞风险的程度。
