The invention relates to a vulnerable traffic participant collision early warning method and system and a storage medium, and the method comprises the steps: obtaining the relative transverse distance between a vehicle and a vulnerable traffic participant and the speed of the vulnerable traffic participant, and determining an early warning scene according to the relative transverse distance and the speed of the vulnerable traffic participant; obtaining a relative speed of the vehicle relative to the vulnerable traffic participant, and calculating an early warning distance corresponding to the early warning scene according to the relative speed; and acquiring a relative distance between the vehicle and the vulnerable traffic participant, and determining whether to perform collision early warning of a corresponding level according to a comparison result of the calculated early warning distance and the relative distance, according to the invention, a driver can be helped to better identify risk sources and threat degrees and avoid the risk sources and the threat degrees.

    本发明涉及一种弱势交通参与者碰撞预警方法及其系统、存储介质,包括:获取本车与弱势交通参与者的相对横向距离与弱势交通参与者的速度,并根据所述相对横向距离与所述弱势交通参与者的速度确定预警场景;获取本车相对于弱势交通参与者的相对速度,根据所述相对速度计算与该预警场景对应的预警距离;以及,获取本车与弱势交通参与者的相对距离,并根据计算的预警距离与所述相对距离的比较结果确定是否进行对应级别的碰撞预警;本发明能帮助驾驶员更好地识别风险来源和威胁程度并进行规避。
