To correctly connect a plurality of maps.SOLUTION: A vehicle position recognition device 50 comprises: a storage unit 12 which stores information about a first map of a first area and information about a second map of a second area adjacent to the first area via an overlapping area with the first area; an own vehicle position recognition unit 13 which recognizes a first position of a vehicle in the overlapping area on the basis of the information of the first map and recognizes a second position of the vehicle in the overlapping area on the basis of the information about the second map; a travel locus generation unit 51 which generates a first travel locus of the vehicle in the overlapping area on the basis of the change following the time course of the first position and generates a second time course of the vehicle in the overlapping area on the basis of the change following the time course of the second position; and a map information update unit 52 which updates the information about the first map such that the first travel locus and the second travel locus overlap with each other on the basis of the first travel locus and the second travel locus.SELECTED DRAWING: Figure 4
【課題】複数の地図を正確に結合する。【解決手段】車両位置認識装置50は、第1エリアの第1地図の情報と第1エリアとの重複領域を介して第1エリアに隣接する第2エリアの第2地図の情報とを記憶する記憶部12と、第1地図の情報に基づいて重複領域における車両の第1位置を認識し、第2地図の情報に基づいて重複領域における車両の第2位置を認識する自車位置認識部13と、第1位置の時間経過に伴う変化に基づいて重複領域における車両の第1走行軌跡を生成し、第2位置の時間経過に伴う変化に基づいて重複領域における車両の第2走行軌跡を生成する走行軌跡生成部51と、第1走行軌跡および第2走行軌跡に基づいて第1走行軌跡と第2走行軌跡とが重なり合うように第1地図の情報を更新する地図情報更新部52とを備える。【選択図】図4
