Claims (6)
- 車両のステアリングホイールの操舵角を検出する操舵角検出手段と、
前記車両の車速を検出する車速検出手段と、
前記操舵角検出手段で検出される前記操舵角をパラメータとして前記車速検出手段で検出される車速の属する所定車速領域毎に、前記車両の前照灯の光軸方向を調整するための制御量が異なる複数のマップを記憶する記憶手段と、
前記記憶手段に記憶された複数のマップのうち現在選択されているマップから前記車速の変化に伴い他のマップに移行させる際には、前記操舵角がその中立位置近傍に設定された所定幅からなるマップ移行許可操舵角領域を経由したのちとするマップ選択手段と、
前記マップ選択手段で選択されたマップを用い前記操舵角に応じて得られる前記制御量に基づき前記前照灯の光軸方向を左右方向にスイブル(Swivel:旋回)させ調整するスイブル制御手段とを具備し、
前記スイブル制御手段は、前記前照灯を消灯状態から点灯状態としたとき、前記マップ移行許可操舵角領域外であったときには、スイブルを禁止し、前記マップ移行許可操舵角領域内になってからスイブル制御を開始することを特徴とする車両用前照灯光軸方向自動調整装置。 - 前記マップ移行許可操舵角領域は、その領域幅を前記車速にかかわらず同じに設定することを特徴とする請求項1に記載の車両用前照灯光軸方向自動調整装置。
- 前記マップ移行許可操舵角領域は、その領域幅を前記車速が高くなるほど狭く設定することを特徴とする請求項1に記載の車両用前照灯光軸方向自動調整装置。
- 前記マップ移行許可操舵角領域は、その領域幅を前記操舵角に応じて得られる前記制御量が零である範囲内に設定することを特徴とする請求項1乃至請求項3の何れか1つに記載の車両用前照灯光軸方向自動調整装置。
- 前記マップ移行許可操舵角領域は、その領域幅を前記操舵角に応じて得られる前記制御量が所定量より小さい範囲内に設定することを特徴とする請求項1乃至請求項3の何れか1つに記載の車両用前照灯光軸方向自動調整装置。
- 前記マップ移行許可操舵角領域は、その領域幅を前記操舵角の左右方向で対称または非対称に設定することを特徴とする請求項1乃至請求項5の何れか1つに記載の車両用前照灯光軸方向自動調整装置。
