Claims (3)
- 車両の姿勢の変化を検出し、前記車両の姿勢の変化を相殺するようにヘッドランプの光軸を調整する自動車用ヘッドランプのオートレベリング装置において、前記ヘッドランプの光軸を車体に対して上下方向に傾動させるアクチュエータと、前記車両の前輪または後輪のうち少なくとも一方の車軸部の高さ方向の変化を検出する車高検出手段と、車両固有の制御定数を記録する制御定数記録手段と、前記制御定数記録手段に記録された前記制御定数は、前記ヘッドランプが車両に組み付けられた後に書き込まれた制御定数か、出荷テストデータの初期値であるか否かを判別する制御定数判別手段と、前記車両固有の制御定数と前記車高検出手段の検出出力に基づいて前記車両の基準姿勢からの変化量を演算し、この演算結果から前記変化量を相殺するように前記アクチュエータの駆動を制御する制御手段とを備え、前記制御手段は、前記制御定数判別手段の判別結果が前者の場合は前記アクチュエータに対する制御を実行し、後者の場合は前記アクチュエータに対する制御を停止してなることを特徴とする自動車用ヘッドランプのオートレベリング装置。
- 指令に応答して点灯または点滅するインジケータを備え、前記制御手段は、前記制御定数判別手段から否定の判別結果が得られたことを条件に前記インジケータに対して点灯または点滅を指令してなることを特徴とする請求項1に記載の自動車用ヘッドランプのオートレベリング装置。
- 前記制御定数判別手段は、前記制御定数記録手段に記録された前記制御定数の判別を電源ON後の最初の1回とすることを特徴とする請求項1または2に記載の自動車用ヘッドランプのオートレベリング装置。
