The invention discloses a vehicle pre-collision early warning method and system based on traffic accident element matching. The method comprises the following steps: extracting accident parameters from a traffic accident case; performing simulation restoration on the traffic accident process based on the extracted accident parameters, and extracting a multi-dimensional time sequence of traffic accident participants from the traffic accident process; importing the multi-dimensional time sequence into a DS-HDP-HMM model to obtain a corresponding hidden state sequence; marking each hidden state as a dangerous state, a secondary dangerous state and a normal state; storing the dangerous state sub-sequence and the secondary dangerous state sub-sequence into an accident state sub-library matched with the traffic accident; acquiring the type of a current road for a vehicle with an early warning demand, and acquiring real-time motion parameters of the vehicle and surrounding traffic participants; and calculating the similarity between the multi-dimensional time sequence of the vehicle and the sequence in the matching sub-library, and carrying out pre-collision early warning on the vehicle with the early warning demand based on the similarity.

    本发明公开了一种基于交通事故要素匹配的车辆预碰撞预警方法与系统,方法包括:从交通事故案例中提取事故参数;基于提取的事故参数对交通事故过程进行仿真还原,并从中提取交通事故参与者的多维时间序列;将多维时间序列导入DS‑HDP‑HMM模型,得到对应的隐状态序列;并将各隐状态标记为危险状态、次危险状态和正常状态;再将危险状态子序列和次危险状态子序列,存入与该交通事故吻合的事故状态子库中;有预警需求的车辆,获取当前所处的道路类型,获取自身以及周围交通参与者实时的运动参数;计算本车辆的多维时间序列与吻合子库中的序列的相似度,并基于相似度对该有预警需求的车辆进行预碰撞预警。
