本发明提出了用于车辆安全行驶所需的多数据融合的方法,包括:利用安装于公路旁的多个路侧传感器采集目标范围内的行驶车辆的动态信息、特征信息、路况信息和交通状态信息;利用安装于车辆上的车载单元,采集行驶车辆的运动状态信息、周围路况和环境信息;路侧服务平台将路侧传感器获取的信息和车载单元获取的信息进行第一次融合;路侧服务平台将D1数据和D2数据进行第二次融合;分析获得异常事件数据信息,将异常事件数据信息再与车辆自身的异常事件数据信息进行第三次融合,得到最终的异常事件信息;将生成的最终的异常事件信息与本区域的高精地图数据进行第四次融合,生成新的高精地图及对应的协同通行方案、预警信息、告警信息、车辆控制信息。
The invention provides a multi-data fusion method for safe driving of vehicles. The method comprises the following steps: acquiring dynamic information, feature information, road condition informationand traffic state information of driving vehicles in a target range by utilizing a plurality of roadside sensors mounted beside a road; acquiring motion state information, surrounding road conditionsand environment information of the driving vehicles by utilizing vehicle-mounted units arranged on the vehicles; through a roadside service platform, performing first fusion on the information acquired by the roadside sensors and the information acquired by the vehicle-mounted units; through the roadside service platform, performing secondary fusion on the D1 data and the D2 data; analyzing to obtain abnormal event data information, and fusing the abnormal event data information with the abnormal event data information of the vehicles for the third time to obtain final abnormal event information; and performing fourth fusion on the generated final abnormal event information and the high-precision map data of the region to generate a new high-precision map and corresponding cooperative traffic schemes, early warning information, alarm information and vehicle control information.
