The invention belongs to the field of Internet of Vehicles, and discloses a vehicle intersection priority passing method and system based on V2X. The method comprises the steps: setting RSU for a roadside communication terminal to receive collected intersection map information, and broadcasting the intersection map information to all vehicle-mounted OBUs; and downloading the intersection map information sent by the RSU by the vehicle-mounted OBUs, comparing the intersection map information with a vehicle real-time position uploaded by a vehicle-mounted GPS, calculating and matching the vehicleposition and the intersection map information in real time through the vehicle real-time position and a map configuration algorithm; and issuing an instruction to a signal lamp through the Ethernet when a priority condition is triggered. The system comprises a vehicle-mounted communication terminal OBU, a roadside communication terminal RSU and an intelligent signal lamp. According to the invention, the traffic efficiency of the special vehicle intersection can be improved to the greatest extent; and the priority passing problem of special vehicles is solved.

    本发明属于车联网领域,公开了一种基于V2X的车辆交叉口优先通行方法及系统,所述方法为路侧通信终端设RSU接收采集的交叉口地图信息,并广播给所有车辆车载OBU;车载终端OBU下载RSU发送的交叉口地图信息,与车载GPS上传的车辆实时位置,通过车辆实时位置与地图配置算法实时计算匹配车辆位置与交叉口地图信息,当优先条件触发时,通过以太网下发指令给信号灯。所述系统包括车载通信终端OBU、路侧通信终端RSU、智能信号灯。本发明能够最大程度提高了特殊车辆交叉路口通行效率;实现了特殊车辆的优先通行问题。
