The invention discloses a method for judging converse running of an automatic driving vehicle. The method comprises the following steps of: acquiring positioning information of a plurality of points during running of the automatic driving vehicle; selecting a one-way driving road section in a road network and dividing the same into N paths connected end to end, and stipulating a starting point and a terminal point; associating the points corresponding to the multiple pieces of positioning information with the paths, calculating the distances between the points and the starting point, under the condition that the distances between the continuous points on a certain path and the starting point are larger and larger, defining a driving direction state as 1, and under the condition that the distances between the continuous points on the certain path and the starting point are smaller and smaller, defining the driving direction state as 0, and meanwhile, assigning the states are to the points; screening out points with the driving direction of 0 between all two continuous points in the same path; and calculating the distance between two adjacent points with the state of 0, and under the condition that the length is greater than a set threshold value, judging that the automatic driving vehicle runs in a reverse direction. No camera needs to be arranged, so that the cost is saved; the driving process of a whole road section can be monitored; and full-automatic operation is achieved, and later-period human resource investment is not needed.

    本发明公开了自动驾驶车辆逆行的判断方法,包括:获取自动驾驶车辆行驶中多个点的定位信息;选定路网中的单向行驶道路路段,拆分成N多个首尾相连的路径,规定起点和终点;将多个定位信息对应的点与路径关联,并计算该点与起点的距离,若某条路径上的连续点与起点的距离越来越大,则行驶方向状态定义为1,若越来越小,则行驶方向状态定义为0,同时将状态赋值至点;筛选出同一条路径内所有连续的两个点间的行驶方向为0的点;计算状态为0的相邻两点间的距离,若长度大于设定阈值,则判定自动驾驶车辆为逆行。本发明不用布置摄像头,节省成本;可对全路段的行驶过程中进行监控;全部自动化运行,无后期人力资源投入。
