The invention discloses a congested road section vehicle anti-collision method, which is suitable for a vehicle equipped with an anti-collision unit, and comprises the following steps: S1, uploading the relative position relationship between the anti-collision unit and the center of the vehicle, the GPS coordinates of the vehicle, the course angle of the vehicle, the ID of the anti-collision unit of the vehicle, and the boundary dimension of the vehicle to a cloud server; s2, when the cloud server monitors that the GPS coordinate distance between the vehicle and other vehicles is smaller than a preset distance D, the cloud server sends a message to the anti-collision units of the vehicle and other vehicles, so that the anti-collision units of the two vehicles establish communication; s3, the distance d and the azimuth angle alpha between the anti-collision unit of the vehicle and the anti-collision units of other vehicles are obtained; the shortest distance L between the vehicle and the outer contour of other vehicles is obtained by combining the boundary dimensions and course angles of other vehicles and the relative position relation between the anti-collision units of other vehicles and the centers of other vehicles; and S4, the vehicle executes early warning, braking and steering according to the value of L.
本发明公开了一种拥堵路段车辆防擦碰的方法,该方法适用于已安装防擦碰单元的车辆,包括以下步骤,S1、将防擦碰单元与自车中心的相对位置关系、自车GPS坐标、自车航向角以及自车防擦碰单元ID、自车外形尺寸上传至云端服务器;S2、当云端服务器监测到自车与其他车辆的GPS坐标距离小于预设距离D时,云端服务器向自车与其他车辆的防擦碰单元发送消息,使两车的防擦碰单元建立通信;S3、获取自车的防擦碰单元与其他车辆的防擦碰单元之间的距离d、方位角α;结合其他车辆的外形尺寸与航向角、其他车辆防擦碰单元与其他车辆中心的相对位置关系,进而得到自车与其他车辆外轮廓的最短距离L;S4、自车根据L的值执行预警、制动以及转向。
