The invention discloses a road state early warning method and device, a vehicle and a storage medium, and relates to the technical field of automobile control. The road state early warning method comprises the steps that road data and real-time vehicle data of a current driving road are acquired, and the road data comprise video data and/or point cloud data; establishing a road three-dimensional model according to the road data; building a finite element structure body model based on the road three-dimensional model; according to the finite element structure body model and the real-time vehicle data, abnormal acceleration is determined in real time, and the abnormal acceleration is vehicle acceleration caused by abnormity of the current driving road; and outputting early warning information according to the abnormal acceleration. The technical problem that the early warning result output by the early warning method is not accurate enough due to the fact that the road state detection is not accurate enough in the current road state early warning method is solved.
本发明公开了一种道路状态预警方法、装置、车辆及存储介质,所涉及的技术领域为汽车控制技术领域。其中,道路状态预警方法包括:获取当前行驶道路的道路数据和实时车辆数据,道路数据包括视频数据和/或点云数据;根据道路数据建立道路三维模型;基于道路三维模型构建有限元结构体模型;根据有限元结构体模型和实时车辆数据实时确定异常加速度,其中,异常加速度为当前行驶道路异常导致的车辆加速度;根据异常加速度,输出预警信息。本发明解决了当前的道路状态预警方法中,对道路状态检测不够准确,进而使预警方法输出的预警结果不够准确的技术问题。
