Description
図1は、実施の形態1に係る制御装置の制御対象である車両用灯具を含む前照灯ユニットの概略鉛直断面図である。前照灯ユニット210は、左右対称に形成された一対の前照灯ユニットが車両の車幅方向の左右に1つずつ配置された構造である。右側の前照灯ユニット210Rおよび左側の前照灯ユニット210Lは実質的に同一の構成であるため、以下では、右側の前照灯ユニット210Rの構造を説明する。
続いて、上述の構成を備える灯具制御ECU100によるレベリング制御について詳細に説明する。図3(A)は、降雪時に前照灯ユニットから光が照射される様子を示す模式図である。図3(B)は、図3(A)に示す状況において運転者から見える様子を示す図である。図4(A)は、基準位置に形成される配光パターンを示す模式図である。図4(B)は、所定の第1位置に形成される配光パターンを示す模式図である。図4(C)は、所定の第2位置に形成される配光パターンを示す模式図である。図3(A)、図4(B)および図4(C)では、雪を丸記号(○)で図示している。
実施の形態2に係る灯具制御ECU100は、車速に応じて配光パターンPの形成位置を変位させる点を除いて、実施の形態1に係る灯具制御ECU100の構成と概ね共通する。以下、実施の形態2に係る灯具制御ECU100について、実施の形態1と異なる構成を中心に説明し、共通する構成については簡単に説明するか、あるいは説明を省略する。
配光パターンの形成位置を変更可能な車両用灯具と、
降雪検知装置と、
上述した車両用灯具の制御装置と、
を備える、車両用灯具システム。
