To readily achieve an accurate grasp of an actual position of a vehicle during automatic traveling.SOLUTION: A vehicle control device includes: an image data acquisition unit for acquiring image data obtained by an on-vehicle camera; a road surface sign data acquisition unit for acquiring road surface sign data related to positions of road surface signs composed of stripe patterns including a first area of a first color extending in a first direction and a second area of a second color different from the first color that is provided to lie adjacent to a second direction orthogonal to the first direction with respect to the first area; a position estimation unit for estimating an actual position of a vehicle by collation between the road surface sign data acquired by the road surface sign data acquisition unit and map data including absolute positions of road surface signs; and a traveling control unit for performing automatic traveling of the vehicle within the parking area by the control of traveling conditions of the vehicle, based on the actual position estimated by the position estimation unit.SELECTED DRAWING: Figure 5 【課題】自動走行中における車両の実位置の正確な把握を簡単に実現する。【解決手段】実施形態の一例としての車両制御装置は、車載カメラによって得られる画像データを取得する画像データ取得部と、画像データに基づく画像認識処理を実施することで、第１方向に延びる第１色の第１領域と、当該第１領域に対して第１方向と交差する第２方向に隣接するように設けられ、第１色とは異なる第２色の第２領域と、を含む縞パターンにより構成された路面標示の位置に関する路面標示データを取得する路面標示データ取得部と、路面標示データ取得部により取得された路面標示データと、路面標示の絶対位置を含む地図データと、を照合することで、車両の実位置を推定する位置推定部と、位置推定部により推定された実位置に基づいて車両の走行状態を制御することで、駐車場内での車両の自動走行を実施する走行制御部と、を備える。【選択図】図５
