PROBLEM TO BE SOLVED: To provide a traffic lane identification apparatus capable of identifying a traffic lane of other vehicle even when ambient visibility is poor.SOLUTION: A map information acquisition section 12 acquires a road map of a present position Po of own vehicle Vo, and a radar unit 13 outputs an irradiation wave and inputs reflection waves to detect relative positions Pa of the other vehicles Va travelling adjacent to the own vehicle Vo. Using the present position Po of the own vehicle Vo on a predetermined XY-coordination, the road map and relative positions Pa of the other vehicles Va are overlapped therewith to identify the traffic lanes LA of the other vehicles Va. That is, a traffic lane LA which has a minimum lateral position (distance Dy) of the other vehicles Va relative to a lane center line LN of traffic lanes LA are identified as the traffic lanes LA of the other vehicles Va.

    【課題】周囲の視認性が低下しているような状況においても、他車両の走行車線を識別する。【解決手段】地図情報取得部12が自車両Voの現在位置Poの道路地図を取得し、レーダ部13による照射波の出力及び反射波の入力によって、自車両Voの周囲を走行している他車両Vaの相対位置Paを検出する。そして、予め定めたXY座標で、自車両Voの現在位置Poを基準に、道路地図、及び他車両Vaの相対位置Paを重畳することにより、他車両Vaの走行車線LAを識別する。すなわち、各走行車線LAの車線中心線LNに対する他車両Vaの横位置(距離Dy)が最小となる走行車線LAを、他車両Vaの走行車線LAとして識別する。【選択図】図1
