The invention relates to an intelligent networked automobile lane-level traffic light information acquisition method, which comprises the following steps that: a V2X cloud platform generates a V2XMAP according to an acquired intersection map, and sends the V2XMAP to a road side unit (RSU); the RSU obtains traffic light control data of the signal control machine, generates SPAT, establishes a corresponding relation between traffic light numbers in the SPAT and lane numbers in the V2XMAP, and sends the corresponding relation and the V2XMAP to the OBU; and the OBU obtains the position information of the vehicle by receiving the differential correction data of the positioning system, determines the driving direction of the vehicle and the serial number of the lane where the vehicle is located by combining the map information in the V2XMAP, obtains the corresponding traffic light serial number phaseID according to the driving direction of the vehicle and the serial number of the lane, obtains the light color and countdown information corresponding to the phaseID according to the SPAT, and displays the light color and countdown information on the display terminal. According to the technical scheme, efficient operation of the intelligent traffic system can be achieved, the road passing efficiency and safety are improved, and technical support is provided for further application in the field of intelligent traffic.

    本发明涉及一种智能网联汽车车道级红绿灯信息获取方法,包括以下步骤:V2X云平台根据采集得到的路口地图生成V2X_MAP,将其发送至路侧单元RSU;RSU获取信控机的红绿灯控制数据并生成SPAT,建立SPAT中红绿灯编号和V2X_MAP中车道编号的对应关系,并将其与V2X_MAP发送至车载单元OBU;OBU通过接收定位系统的差分修正数据得到自车位置信息,结合V2X_MAP中的地图信息确定自车行驶方向和所在车道编号,根据自车行驶方向和车道编号获取对应的红绿灯编号phase_ID,根据SPAT得到该phase_ID对应的灯色与倒计时信息,显示终端进行显示。该技术方案可实现智能交通系统的高效运行,提高道路通行效率和安全性,并为智能交通领域的进一步应用提供了技术支持。
