To enable more accurate estimation of a traveling position of an own vehicle on a road even at locations other than intersections.SOLUTION: A vehicle location estimation device includes: a traveling environment recognition unit 102 that is used in a vehicle to recognize a traveling environment including the number of lanes on a travel path for a vehicle from sensing results of a peripheral monitoring sensor 50 that monitors the periphery of the vehicle; a map data acquiring unit 104 that acquires map data including the number of lanes on a road for each area; and a position estimation unit 107 that estimates a traveling position of the vehicle on the road on the basis of the degree of similarity between the number of lanes on the travel path of the vehicle recognized by the traveling environment recognition unit 102 and the number of lanes in the area estimated to be a traveling area of the vehicle acquired by the map data acquiring unit 104.SELECTED DRAWING: Figure 1
【課題】交差点以外の場所であっても、道路上における自車の走行位置をより精度良く推定することを可能にする。【解決手段】車両で用いられ、車両の周辺を監視する周辺監視センサ50でのセンシング結果から、車両の走路の車線数を含む走行環境を認識する走行環境認識部102と、領域別の道路の車線数を含む地図データを取得する地図データ取得部104と、走行環境認識部102で認識する車両の走路の車線数と、地図データ取得部104で取得する、車両の走行領域と推定される領域の車線数との、類似度合いをもとに、道路上の車両の走行位置を推定する位置推定部107とを備える。【選択図】図1
