The invention discloses a vehicle converse running detection method and system and a vehicle. The method comprises the steps: acquiring the current driving track of a vehicle through a GPS positioningmodule on the vehicle; obtaining a current driving track point, a previous driving track point and a next driving track point of the vehicle from the current driving track, selecting a plurality of line segments closest to the current driving track point, the previous driving track point and the next driving track point from pre-stored road network information, and obtaining an intersection of the plurality of line segments to obtain road segment information closest to the current driving track; obtaining a road section vector by obtaining a starting point and an ending point in the road section information, and obtaining a driving vector of the vehicle through the current driving track point; according to the inclined angle between the road section vector and the driving vector, judgingwhether the vehicle is in converse running or not. According to the invention, a large number of cameras do not need to be installed, the installation position requirements of the cameras do not needto be considered, and the cost is low; moreover, the method is based on software automatic detection, and is high in accuracy and high in real-time performance.
一种车辆逆行检测方法、系统及车辆,该方法包括:通过车辆上的GPS定位模块获取车辆的当前行驶轨迹;从当前行驶轨迹中获取车辆的当前行驶轨迹点、上一个和下一个行驶轨迹点,并从预存的路网信息中选取离当前行驶轨迹点、上一个和下一个行驶轨迹点最近的若干条线段,且获取若干条线段的交集得到离当前行驶轨迹最近的路段信息;通过获取路段信息中的起点和终点得到该路段矢量,以及通过当前行驶轨迹点获取车辆的行驶矢量;并根据路段矢量与行驶矢量的夹角判断车辆当前是否为逆行状态,本发明车辆逆行检测方法、系统及车辆不需要安装大量摄像头,不用考虑摄像头的安装位置要求,成本低;而且,本发明基于软件自动检测,准确度高,且实时性高。
