The invention relates to a vehicle early warning method and device for driving risks, a vehicle and a storage medium, and the method comprises the steps: obtaining a plurality of scene events when the vehicle is driven in a target evaluation site and driving parameters corresponding to each scene event; comparing the distance between the event coordinate point of each scene event and a preset style coordinate point one by one, and determining the driving styles of the driver under different scene events; and determining a transverse driving risk value and a longitudinal driving risk value of the driver according to the occurrence frequency of each driving style in different scene events, and constructing a driving risk model of the driver in combination with the scene parameters so as to perform driving risk early warning on the current driving scene of the vehicle by using the driving risk model. Therefore, the technical problems that the analysis result is inaccurate and the accuracy of follow-up driving risk assessment is affected due to the fact that the driving style is determined according to the driver operation data of the vehicle under different driving working conditions, the analysis process is rough and the characteristics of the driver are submerged in the analysis process in the related technology are solved.
本申请涉及一种驾驶风险的车辆预警方法、装置、车辆及存储介质,其中,方法包括:获取车辆在目标评估场地行驶时的多种场景事件以及每种场景事件对应的行驶参数;逐一对比每种场景事件的事件坐标点和预先设置的风格坐标点之间的距离,确定驾驶员在不同场景事件下的驾驶风格;根据每种驾驶风格在不同场景事件中的出现频率,确定驾驶员的横向驾驶风险值和纵向驾驶风险值,并结合场景参数构建驾驶员的驾驶风险模型,以利用驾驶风险模型对车辆的当前驾驶场景进行驾驶风险预警。由此,解决了相关技术中,根据车辆在不同驾驶工况下的驾驶员操作数据确定驾驶风格,分析过程比较粗糙,且会淹没驾驶员本身特性,导致分析结果不准确,影响后续驾驶风险评估的准确性的技术问题。
