The invention relates to a driving risk identification and early warning method, system and device and a medium. The method comprises the following steps: collecting a driving environment and driving data of a vehicle; fitting real-time parameters of a high-risk driving model through a genetic algorithm based on a vehicle driving environment and driving data to obtain model parameters representing driver operation characteristics and vehicle motion characteristics; based on the model parameters obtained through fitting, high-risk driving behaviors are classified and recognized through an SVM classification algorithm, and early warning is conducted on driving risks. According to the method, traffic safety is used as guidance, driving risk comprehensive evaluation and early warning under coupling influence factors are carried out by using driving data, namely, the coupling influence relationship of a driver-vehicle system, a road environment, individual characteristics of a driver and a driving state is comprehensively considered, and the driving risk is identified and early warned. The method can be widely applied to the field of driving safety.

    本发明涉及一种驾驶风险识别预警方法、系统、设备和介质,包括以下步骤:对车辆的驾驶环境及行车数据进行采集;基于车辆驾驶环境及行车数据,通过遗传算法进行高风险驾驶模型实时参数的拟合,得到表征驾驶员操作特性以及车辆运动特性的模型参数;基于拟合所得的模型参数,通过SVM分类算法进行高风险驾驶行为的分类识别,并对驾驶风险进行预警。本发明以交通安全为导向,利用行车数据开展耦合影响因素下的驾驶风险综合评估与预警,即综合考虑“驾驶人‑车辆”系统受道路环境以及驾驶人个体特征、驾驶状态的耦合影响关系,进行驾驶风险的识别与预警。本发明可以广泛应用于驾驶安全领域。
