The invention is suitable for the technical field of communication, and provides a road information acquisition method and a road information service method. The method comprises the following steps: receiving a first message transmitted by roadside equipment through a 5.8 GHZ frequency band through a first vehicle-mounted unit, wherein the first message carries road sign prompt information; the first vehicle-mounted unit transmits the first message to the second vehicle-mounted unit through a serial port; the second vehicle-mounted unit analyzes the first message to obtain the road sign prompt information, so that the message carrying the road sign prompt information can be received through the 5.8 GHZ frequency band under the condition that V2X scene triggering is required, and the message does not need to be received on the transmission frequency band of the V2X message; the data volume of the information transmitted at the 5.8 GHZ frequency band is small, so that the data transmission efficiency is improved; and in a place where V2X equipment is imperfect, the road sign prompt information can also be obtained.
本申请适用于通信技术领域,提供了一种道路信息获取方法及道路信息服务方法。所述方法包括:通过第一车载单元接收路侧设备通过5.8GHZ频段传输的第一消息,第一消息携带道路标牌提示信息;第一车载单元通过串口将第一消息传输给第二车载单元;第二车载单元对第一消息进行解析,得到道路标牌提示信息,使得在需求V2X场景触发的情况下,也能够通过5.8GHZ频段接收携带道路标牌提示信息的消息,无需在V2X消息的传输频段上接收信息;因5.8GHZ频段传输的信息的数据量较小,从而提高数据传输效率;并且在V2X设备不完善的场所中,也能够得到道路标牌提示信息。
