PROBLEM TO BE SOLVED: To provide a traveling partition line recognition device in which stability of recognition suppression of traveling partition line in disorderly road environment unsuitable for recognition of the traveling partition line is compatible with response incident to sudden change of road environment.SOLUTION: A traveling partition line recognition device includes calculation means for calculating the disorderliness of a camera image having impact on the recognition of traveling partition line of a road, learning means for updating the disorder learning value based on the disorderliness calculated this time by the calculation means, and the disorder learning value that is the learning value of disorderliness in the past, suppression means for suppressing recognition of the traveling partition line when the disorder learning value updated by the learning means exceeds a threshold, determination means for determining whether or not the environment of road is before and after change, and learning reset means for returning the disorder learning value to the previous value, if the determination means determines that the environment is before and after change.SELECTED DRAWING: Figure 1

    【課題】走行区画線の認識に不適な乱雑な道路環境における走行区画線の認識抑制の安定性と、道路環境への急変に伴う応答性とを両立可能な走行区画線認識装置を提供する。【解決手段】道路の走行区画線の認識に影響するカメラ画像の乱雑度合を算出する算出手段と、算出手段により今回算出された乱雑度合と、過去の乱雑度合の学習値である乱雑学習値とに基づいて、乱雑学習値を更新する学習手段と、学習手段により更新された乱雑学習値が閾値を超えた場合に、走行区画線の認識を抑制する抑制手段と、道路の環境が変化する前後か否かを判定する判定手段と、判定手段により前記環境が変化する前後と判定された場合に、乱雑学習値を今よりも前の乱雑学習値に戻す学習リセット手段と、を備える。【選択図】 図1
