The invention provides a vehicle driving early warning method and device, electronic equipment and a storage medium, and the method comprises the steps: determining at least two to-be-merged micro behaviors corresponding to a vehicle within a preset time period based on the driving parameters of the vehicle; the to-be-merged micro-behaviors refer to micro-behaviors which meet preset merging conditions and form meaningful composite behaviors; based on the operation parameters corresponding to the to-be-merged micro behaviors, determining scores of the to-be-merged micro behaviors; based on a preset weight, carrying out weight addition on the scores of the to-be-combined micro behaviors to obtain a score of a composite behavior; the preset weight can be obtained based on experience or through training of a machine learning method; the composite behavior is obtained by combining the to-be-combined micro behaviors; and if the score of the composite behavior is less than a preset value, carrying out driving early warning. Due to the fact that characterization of the micro-behaviors is simple and direct, the micro-behaviors can be rapidly and accurately recognized to obtain the micro-behaviors, the score of the composite behaviors is obtained on the basis of the micro-behaviors, efficiency is high, and simplicity and rapidness are achieved.
本发明提供一种车辆驾驶预警方法、装置、电子设备和存储介质,所述方法包括:基于车辆的行驶参数,确定预设时段内车辆对应的至少两个待合并微行为;待合并微行为指满足预设合并条件,构成有意义复合行为的微行为;基于各待合并微行为对应的操作参数,确定各待合并微行为的评分;基于预设权重,对各待合并微行为的评分进行权重相加,得到复合行为的评分;预设权重可基于经验或通过机器学习方法训练得出;复合行为是对各待合并微行为进行合并后得到的;若复合行为的评分小于预设值,则进行驾驶预警。由于微行为的表征简单直接,从而可以快速且准确进行识别得到微行为,并在微行为的基础上得到复合行为的评分,不仅效率较高,而且简单快捷。
