Description
ヘッドランプ6、7は、車両の左右に一対設けられて前方を照射するランプである。図2に示すように、光源11、レンズ12、シェード機構13、アクチュエータ14を有している。光源11はハロゲンランプである。シェード機構13は、不図示の複数のシェード板を有し、ECU5の制御部53からの指示により、光路の一部に挿抜されて、遮光することにより、中間ハイビームパターンやロービームパターンを形成する。光路から完全に退避することによりハイビームパターンとする。ヘッドランプ6、7は、それぞれ、これら3つの配光パターンを有している。
(前方車両がある場合)
つづいて、車載カメラ2からの情報を基に、前方車両の有無を判定する(S−2)。前方車両がある場合(S−2:Y)、車載カメラ2の情報をECU5の画像処理部51で画像処理し、たとえば先行車のテールランプや、対向車のヘッドランプの明かりを基に、前方車両の左右両端の座標を算出する。また、この座標から、ヘッドランプを前方車両に追従させるためのスイブル角度を算出する(S−4)。
(前方車両がない場合)
S−2で、前方車両がない場合(S−2:N)、S−1で計算した旋回半径を所定値R2と比較する(S−3)。ここではR2を100[m]とした。前方車両がある場合の配光制御では、旋回半径が100[m]以上のカーブは直線と同じ扱いとなる。
