- 複数の空気ばねを有する車高制御装置、空気ばね構成体内の総空気量を測定するための装置、及び温度を感知するための装置を備える自動車空気ばね構成体において漏洩を検出するための方法であって、
前記空気ばね構成体内の総空気量Q1が第1の瞬時t1において測定されるとともに前記空気ばね構成体内の総空気量Q2が第2の瞬時t2において測定され、これらの量が前記空気ばね構成体内に存在する空気の温度の感知の結果得られる温度依存係数により補正されるとともに、前記温度補正された総空気量Q1とQ2との間の差が求められることにより、前記差が特定の限界値QGrenzだけ超過する時に前記空気ばね構成体における漏洩が特定されるようになっていて、
総空気量Q1、Q2を測定する時、自動車空気ばね構成体内の空気の圧力を測定する複数の圧力センサ及び空気ばねの高さを測定する複数の高さセンサの計測値が評価され、
前記空気ばね構成体の総空気量Q1、Q2が、前記個々の空気ばね内の空気量及び圧縮空気タンク内及び前記圧縮空気タンクを前記空気ばねに個々の逆止弁を介して接続する空気ライン内の空気量の合計から決定され、
総空気量Q1とQ2との間に差が生じたときに、外部から前記空気ばね構成体に供給される空気量Qin及び/又は環境中に放出される空気量Qausを考慮する一方、
前記2つの瞬時t 1 とt 2 との間にいずれかの逆止弁が開放されなかった場合、該逆止弁に対応する空気ばねに対して、該空気ばね内の空気量に基づいて漏洩の検出を行うことを特徴とする方法。 - 前記方法が静止した前記自動車で実行されることを特徴とする、請求項1に記載の方法。
- 前記方法が前記自動車の負荷条件が変化しない時に実行されることを特徴とする、請求項1又は2に記載の方法。
