The invention relates to a driving risk early warning method based on intelligent network connection automobile operation scene analysis. The method comprises the following steps: obtaining dynamic and static scene elements influencing the driving safety of an intelligent network connection automobile; obtaining a relative position relation and motion track characteristics between the intelligent network connection vehicle and surrounding vehicles, and judging an interaction type between the vehicles; calculating road environment complexity reflecting scene static characteristics and traffic flow states reflecting scene dynamic characteristics based on the dynamic and static scene elements; based on the interaction type between the vehicles, constructing a risk measurement model between the intelligent networked vehicle and the surrounding vehicles by using a risk evaluation index; determining a driving risk level based on the road environment complexity, the traffic flow state and a risk measurement model; and based on the driving risk level, driving risk grading early warning of the intelligent networked vehicle is realized. Compared with the prior art, risk early warning can be carried out on the intelligent networked automobile in advance.

    本发明涉及一种基于智能网联汽车运行场景解析的行驶风险预警方法,该方法包括以下步骤:获取影响智能网联汽车行驶安全的动静态场景要素;获取智能网联汽车与周边车辆之间的相对位置关系和运动轨迹特征,判断车辆之间的交互类型;基于所述动静态场景要素,计算反映场景静态特征的道路环境复杂度,以及反映场景动态特征的交通流状态;基于所述车辆之间的交互类型,利用风险评价指标,构建智能网联汽车与周边车辆之间的风险度量模型;基于所述道路环境复杂度、交通流状态和风险度量模型,确定行驶风险等级;基于所述行驶风险等级,实现智能网联汽车行驶风险分级预警。与现有技术相比,本发明能够对智能网联汽车提前进行风险预警。
