The invention relates to the technical field of road driving early warning calibration and particularly relates to a V2X-based road abnormal vehicle early warning method and system. The early warningmethod is applied to a V2X road abnormal vehicle early warning system. The early warning method comprises steps of the dynamic information sent by road driving vehicles within a preset range being received; according to the dynamic information, calculating and planning to obtain a predicted driving track corresponding to the vehicle; monitoring the driving state of the vehicle, and judging whetherthe vehicle has sudden driving change or not according to the predicted driving track of the vehicle; if so, marking the abrupt change vehicle, and continuously monitoring the vehicle; and if the vehicle has the preset abnormal action, sending abnormal vehicle early warning information to vehicles around the vehicle. According to the method, abnormity monitoring is carried out on the vehicle through the roadside unit, and the early warning information is sent to the surrounding vehicles after the vehicle is determined to be an abnormal vehicle, so the occurrence rate of road vehicle collisiontraffic accidents is greatly reduced, the road driving safety is greatly improved, and a problem that the current vehicle abnormity early warning difficulty is relatively large is solved.
本发明涉及道路行车预警标定技术领域,尤其涉及一种基于V2X的道路异常车辆预警方法及系统。应用于V2X的道路异常车辆预警系统,所述预警方法包括:接收预设范围内的道路行驶车辆发送的动态信息;根据动态信息,计算规划得出车辆对应的预测行驶轨迹;监测车辆行驶状态,并根据车辆的预测行驶轨迹判断车辆是否存在行车突变;若是,标记突变车辆,并对该车辆进行持续监控;若该车辆发生预设异常动作,向该车辆周边车辆发送异常车辆预警信息。本发明通过路边单元对车辆进行异常监控,确认车辆为异常车辆后,向周边车辆发送预警信息,从而大幅度降低道路汽车相撞交通事故的发生率,大大提高道路行驶的安全性,解决当前汽车异常预警难度较大的问题。
