摘　　要：传统独立的汽车定位方法依赖于车辆位姿,导致通信网络定位结果存在偏差和不稳定的问题,为此提出融合云平台和地图匹配算法的新能源汽车通信网络定位方法。获取新能源汽车在通信网络中的位置信息,搭建新能源汽车的视觉地图,在云平台上嵌入地图匹配算法,匹配汽车位置信息与视觉地图中道路信息,得到新能源汽车的定位轨迹,完成新能源汽车通信网络定位研究。实验结果表明,文章定位方法下新能源汽车通信网络单点定位精度可以控制在20 cm之内,累积误差较小,能够获得较好的稳定性效果。Because the traditional independent vehicle positioning method depends on the position and posture of the vehicle,the positioning results of the communication network are biased and unstable.Therefore,a new energy vehicle communication network positioning method integrating cloud platform and map matching algorithm is proposed.Obtain the location information of new energy vehicles in the communication network,build a visual map of new energy vehicles,embed a map matching algorithm in the cloud platform,and match the vehicle location information with the road information in the visual map to obtain the positioning trajectory of new energy vehicles,thus completing the positioning research of new energy vehicles in the communication network.The experimental results show that the single-point positioning accuracy of new energy vehicle communication network can be guaranteed within 20 cm,and the cumulative error is small,which can obtain better stability effect.
