To provide a preceding vehicle identification device whereby, on a road on which a user's own vehicle travels, another vehicle that is not a preceding vehicle ahead of the user's vehicle is mistakenly identified as the preceding vehicle.SOLUTION: The preceding vehicle identification device 1 comprises: a user's own vehicle information acquisition unit 121 that acquires own vehicle information including a traveling direction and a position of the own vehicle traveling on a road; an other vehicle information acquisition unit 122 that acquires other vehicle information including a traveling direction and a position of the other vehicle by vehicle-to-vehicle communication; a front vehicle extraction unit 123 that extracts the other vehicle which is within a determination distance between the traveling direction of the own vehicle and the traveling direction of the other vehicle, and exists in front of the traveling direction of the own vehicle based on the own vehicle information and the other vehicle information; and a preceding vehicle identification unit 125 that identifies a preceding vehicle based on whether a relationship between the other vehicle's travel locus, which is a history of the position of the other vehicle extracted by the front vehicle extraction unit, and the own vehicle's travel locus, which is a history of the position of the own vehicle, meets a matching criteria to identify the preceding vehicle traveling on the road.SELECTED DRAWING: Figure 2

    【課題】自車が走行する道路を先行する先行車両ではない他車を先行車両として特定してしまうことを抑制する。【解決手段】先行車両特定装置1は、道路を走行中の自車の走行方位と位置とを含む自車情報を取得する自車情報取得部121と、車車間通信により他車の走行方位と位置とを含む他車情報を取得する他車情報取得部122と、自車情報と他車情報とに基づいて、自車の走行方位と他車の走行方位との差が判定距離内であり、かつ自車の進行方向前方に存在する他車を抽出する前方車両抽出部123と、前方車両抽出部が抽出した他車の位置の履歴である他車走行軌跡と、自車の位置の履歴である自車走行軌跡との関係が道路を走行する先行車両を特定するためのマッチング条件を満たすか否かに基づいて先行車両を特定する先行車両特定部125と、を備える。【選択図】図2
