The invention belongs to the technical field of automatic driving, and particularly relates to a network connection cooperative driving automobile curve collision early warning method and system, and the method comprises the steps that a roadside RSU collects vehicle state information and curve environment information, and uploads the vehicle state information and the curve environment information to an edge cloud; the edge cloud carries out fusion analysis on the input data, and a Bi-LSTM network is adopted to predict a driving track of a non-networked automobile at a curve; an intelligent networked automobile driving risk field model is established, and the curve driving collision risk is evaluated in real time in combination with a surrounding automobile prediction track; calculating a collision risk threshold value by utilizing a Monte Carlo rule and combining human driving data, and performing curve collision early warning; the intelligent L2-level intelligent automobile environment perception is enabled through network connection, the curve driving collision early warning model is established, the problems of missing report and false report of the collision early warning system can be effectively reduced, and therefore the driving safety and efficiency are improved.

    本发明属于自动驾驶技术领域,具体涉及一种网联协同驾驶汽车弯道碰撞预警方法及系统,所述方法包括:路侧RSU采集车辆状态信息与弯道环境信息,并上传至边缘云;边缘云对输入数据进行融合解析,并采用Bi‑LSTM网络预测弯道处非联网汽车的行驶轨迹;建立智能网联汽车行车风险场模型,结合周围车辆预测轨迹,实时评估弯道行驶碰撞风险;利用蒙特卡洛法则,结合人类驾驶数据计算碰撞风险阈值,进行弯道碰撞预警;本发明通过网联赋能智能L2级智能汽车环境感知,建立弯道行驶碰撞预警模型,能够有效减少碰撞预警系统的漏报与误报问题,从而提高行车的安全性与效率。
