The invention provides a prompt method and device for abnormal deceleration of a motor vehicle on a highway section and a storage medium. The method comprises the following steps: updating speed data of all running motor vehicles in a highway section in a certain period; performing abnormity judgment on the speed data of each running motor vehicle in the current updating period, namely acquiring a speed sudden change value in a preset time threshold range, and comparing the acquired speed sudden change value with a normal sudden change threshold, so as to determine the motor vehicle with abnormal running speed; speed data and position data of the motor vehicle with the abnormal running state are obtained, the abnormal speed data and the abnormal position data are pushed to target vehicles, and the target vehicles comprise running vehicles within the early warning range of the vehicles with the abnormal running state. By means of the satellite positioning technology, the abnormal running speed of the motor vehicles on the highway can be rapidly recognized, meanwhile, the motor vehicles within a certain range of the upstream of an accident are rapidly prompted based on the navigation platform, and more sufficient emergency response time is provided for a driver.
本发明提供一种高速路段机动车异常减速提示方法、装置及存储介质。方法包括:以一定周期更新高速路段内所有运行机动车的速度数据;在当前更新周期内对每一运行机动车的速度数据进行异常判断,包括在预设的时间阈值范围内获取速度突变值,比较获取的速度突变值与正常突变阈值,从而确定运行速度异常的机动车;获取运行状态异常的机动车的速度数据和位置数据,并将异常速度数据和位置数据推送至目标车辆,所述目标车辆包括为运行状态异常车辆预警范围内的运行车辆。本发明借助卫星定位技术,实现高速路上机动车辆行车速度异常的快速识别,同时基于导航平台,对事故上游一定范围内的机动车辆进行快速提示,给予驾驶员更充足的应急响应时间。
