The invention discloses a roadblock prediction method based on a vehicle-to-outside information interactive communication technology, and the method comprises the steps: 1, obtaining the merging auxiliary information of vehicles around a vehicle, building a front vehicle behavior list, and updating the front vehicle behavior list in real time; 2, taking the vehicle farthest from the vehicle in the front vehicle behavior list as a target vehicle, recording the position of a lane changing center point when the target vehicle changes a lane, and updating the target vehicle in real time; 3, acquiring at least two lane changing center point positions, and when the distance between the lane changing center points is smaller than a first distance threshold value, predicting that abnormity exists in front; and 4, according to the central point position and the target vehicle speed, predicting whether there is an obstacle in front based on a driving map. Under the condition that the vehicle runs without the coverage of the roadside unit, according to the lane changing behavior of the front vehicle, the roadblock is predicted for early warning, the collision risk is avoided, and the road passing efficiency is improved.

    本发明公开了一种基于车对外界信息交互通信技术的路障预测方法,包括步骤一、获取本车周围车辆的并线辅助信息,建立前车行为列表,并实时更新前车行为列表;步骤二、将前车行为列表中距离本车最远的车辆作为目标车辆,当目标车辆变道时,记录变道中心点位置,并实时更新目标车辆;步骤三、获取至少两个变道中心点位置,当变道中心点间的距离小于第一距离阈值时,预测前方存在异常;步骤四、根据所述中心点位置、目标车辆车速,并基于行车地图,预测前方是否存在障碍物。本发明在车辆行驶在没有路侧单元覆盖的情况下,根据前车的变道行为,预测路障提前预警,规避碰撞风险,提高道路通行效率。
