The invention relates to the technical field of automobile navigation, in particular to an intelligent updating method and system for an automatic driving navigation map, and aims to obtain the space influence of each congestion area on a target area based on the change of navigation path planning and obtain the time difference of congestion of each congestion area and the target area. According to the method, the correlation between the congestion phenomenon of each congestion area and the target area is obtained, the time influence is obtained through the correlation, the time influence of each congestion area on the target area is determined, the initial traffic flow of the target area is corrected according to the space influence and the time influence, and the accurate and real traffic flow of the target area can be obtained. The accuracy of vehicle flow acquisition is improved, and the accuracy of map updating priority acquisition is improved.
本发明涉及汽车导航技术领域,具体涉及一种自动驾驶导航地图的智能更新方法及系统,基于导航路径规划的改变,获取各拥堵区域对目标区域的空间影响,结合各拥堵区域与目标区域拥堵出现的时间差,得到各拥堵区域与目标区域的拥堵现象的相关性,由相关性得到时间影响,从而确定各拥堵区域对目标区域的时间影响,根据空间影响和时间影响,对目标区域的初始车流量进行修正,能够得到目标区域的准确真实的车流量,提升车流量获取的准确性,从而提升地图更新优先级获取的准确性。
