The invention discloses a vehicle accident identification method and device, relates to the technical field of Internet of Vehicles, and aims to solve the problem that accident behaviors of vehicles on a road cannot be accurately identified due to the fact that no monitoring camera is installed on the road. According to the specific technical schemes, the vehicle accident identification method compromises the following steps that: a vehicle accident recognition device obtains all initial time points in a first time period and vehicle data of a target vehicle at each initial time point; at least one candidate accident time point is determined in all the initial time points according to the vehicle data of each initial time point; according to each candidate accident time point and a preset classification model, an accident probability corresponding to each candidate accident time point is determined, wherein the accident probability is the probability that the target vehicle has an accident; and the candidate accident time point corresponding to the maximum accident probability in the at least one candidate accident time point is determined as a target accident time point.
本发明公开一种车辆事故识别方法及装置,涉及车联网技术领域,解决了由于道路上未安装监控摄像头导致无法准确地识别该道路上车辆的事故行为的问题。具体方案为:车辆事故识别装置获取第一时间段内的所有初始时间点,以及目标车辆在每个初始时间点的车辆数据;根据每个初始时间点的车辆数据,在所有初始时间点中确定至少一个候选事故时间点;根据每个候选事故时间点和预设的分类模型,确定每个候选事故时间点对应的事故概率,事故概率为目标车辆发生事故的概率;将至少一个候选事故时间点中,最大的事故概率对应的候选事故时间点确定为目标事故时间点。
