A position estimation system for estimating the position of a vehicle, which is provided with a magnetic sensor for measuring magnetism acting from the road surface side forming the surface of a traveling road, comprises: a map DB for storing a map (1) associated with a road surface magnetism distribution (M2), which is the distribution of the amount of magnetism at each point on the road surface; a magnetic distribution generation unit that acquires magnetic measurement values obtained by the magnetic sensor and generates a measurement magnetic distribution that is a distribution of the magnetic measurement values; and a position estimation unit that specifies a region corresponding to the measured magnetic distribution in the road surface magnetic distribution (M2) associated with the map stored in the map DB, and estimates the position of the host vehicle on the basis of the position of the region corresponding to the measured magnetic distribution on the map.
具备对从形成行驶路的表面的路面侧作用的磁进行计测的磁传感器的车辆推定本车位置的位置推定系统包括:地图DB,其存储与作为路面的各点的磁量的分布的路面磁分布(M2)建立了对应关系而成的地图(1);磁分布生成部,其取得由磁传感器得到的磁计测值,并生成作为磁计测值的分布的计测磁分布;以及位置推定部,其确定与地图DB所存储的地图建立了对应关系的路面磁分布(M2)中的与计测磁分布对应的区域,并基于与计测磁分布对应的区域在地图上的位置来推定本车位置。
