The invention discloses an automatic emergency braking method and system based on vehicle-road cooperation. The method comprises the steps that S1 GNSS track point lines of a dangerous region are marked according to a vehicle driving route, and the GNSS track point lines are stored in a background database; S2 vehicle positioning is carried out through a GNSS tracking device, and the intelligent controller regularly pulls the latest GNSS track point line from the background database to the local for caching; S3 arranging a road sign sensor on the fence of the dangerous region; and S4 when thevehicle runs to the dangerous region, the intelligent controller performs the following operations that the intelligent controller communicates with the road sign sensor, and the road sign sensor provides fence position information and information about whether the vehicle belongs to a dangerous side or not; a millimeter-wave radar is started, and the fence is detected to obtain a fence curve; andbased on the fence position information, the information about whether the fence belongs to the dangerous side, the fence curve and the vehicle posture, if the vehicle is judged to have the possibility of colliding or rushing out of the dangerous side fence, braking measures are taken for the vehicle.

    本发明公开了一种基于车路协同的自动紧急制动方法及系统,其方法包括:S1、根据车辆行驶路线,标注出危险区域的GNSS轨迹点线并存储在后台数据库中;S2、通过GNSS跟踪装置进行车辆定位,智能控制器定时从后台数据库中拉取最新的GNSS轨迹点线到本地进行缓存;S3、在危险区域的栅栏上设置路标传感器;S4、当车辆行驶到危险区域时,所述智能控制器进行如下操作:与路标传感器进行通讯,所述路标传感器提供栅栏位置信息及是否属于危险侧信息;开启毫米波雷达,对栅栏进行检测,获得栅栏曲线;基于栅栏位置信息、栅栏是否属于危险侧信息、栅栏曲线及车辆姿态,若判断车辆有碰撞或冲出危险侧栅栏的可能性,则对车辆采取制动措施。
