PROBLEM TO BE SOLVED: To provide a highly accurate position acquisition system.SOLUTION: A position acquisition system 1 includes: approach detection means 101 configured to detect that a host vehicle is approaching an intersection, a specific point on a travel route, when a radio wave from a radio beacon installed at the intersection is received; and a marker detection unit 122 configured to detect magnetic markers disposed on a surface of a road the vehicle is travelling on. The system is configured to acquire a position of the vehicle upon detection of an approach to a specific point such as an intersection from the beacon radio wave and of a magnetic marker.SELECTED DRAWING: Figure 1
【課題】精度の高い位置捕捉システムを提供すること。【解決手段】位置捕捉システム1は、走行経路上の特定箇所である交差点に設置された電波ビーコンの電波を受信したときに交差点への接近を検知する接近検知手段101と、車両が走行する路面に配置された磁気マーカを検知するマーカ検知ユニット122と、を備え、ビーコン電波の受信に応じて交差点などの特定箇所への接近を検知した状態で磁気マーカを検知したときに車両の位置を捕捉する。【選択図】図1
