Abstract
Description
a) センサー手段の内部温度センサー、或いは、内部温度シグナルを車両のスタート時、或いは、走行開始時に、車両ガラスの凍結が有り得るか(例えば、温度<0°C,< 3°C,<4°Cである)、或いは、車両ガラス上に氷がある確率が高いかを判断することに採用する。車両が、気温がマイナス時にスタートされると、ある一定期間、一つの、或いは、複数の検出閾値が、高めに設定される。
terhoehte Detektionsschwelle f(Tzum Startzeitpunkt)
[t検出閾値を高めに設定f(Tスタート時点)]
式中:terhoehte Detektionsschwelle[t検出閾値を高めに設定]は、検出閾値が、高めに設定されている期間の長さであり、Tzum Startzeitpunkt[Tスタート時点]は、内部で測定されたシステム・スタート時点の温度を示している。
b)内部温度センサー、或いは、内部温度シグナルを、ケースa)同様に、採用する。但し、車両が、マイナス温度、或いは、氷点下を僅かに超える温度において始動された場合、高めに設定された検出閾値が、採用されるが、それは、一定期間、並びに、温度が正の値に達する、或いは、ある正の値の温度(例えば、0°C、1°C、2°C、3°C、或いは、4°Cを超える温度)が得られるまで維持される。
c)内部温度センサー、或いは、内部温度シグナルを、ケースa)、b)同様に、採用する。但し、不揮発性メモリーにノード、特に好ましくは、氷点(摂氏0度付近)に設定することによって、内部温度をより正確に得る。ノードを採用することは、特に、温度センサーが、実際の温度と一次比例していない場合に有利である。ノードを用いる方法は、図1のように、T1からT6のノードと温度センサーのカーブABKによって、表現できる。
Tinnen=センサー手段のセンサー・ハウジング内の温度であり、これ(T内部)は、少なくとも一つの内部/内蔵温度センサーによって測定される。
Claims (9)
- 車両内のガラスの後ろに配置されている少なくとも一つのセンサー手段のシグナル処理を適応させる、但し、測定された温度から、ガラス上に氷がある確率が認められた場合に、該シグナル処理の適応に、少なくとも一つの検出閾値の変更が含まれている、適応方法であって、
ガラス上の氷の存在確立を割出すに当たってセンサー手段内に内蔵されている少なくとも一つの温度センサーの温度シグナルが採用されることを特徴とするシグナル処理の適応方法。 - 少なくとも一つの温度センサーが、本質的に、センサー手段内の少なくとも一つの他の機能ことを実施するために内蔵されていることを特徴とする請求項1に記載の方法。
- 少なくとも一つの温度センサーの温度シグナルは、車両が始動された時点においてのみ、ガラス上に氷が存在する確率を割出すために用いられることを特徴とする請求項1或いは2のいずれかに記載の方法。
- 該少なくとも一つの他の機能が、特に好ましくは、オーバーヒートを回避するための、センサー手段の作動温度の継続的な測定であることを特徴とする請求項2或いは3のいずれかに記載の方法。
- 少なくとも一つの温度センサーによる温度の割出の際に、不揮発性メモリー内のノードが使用されることを特徴とする先行請求項のうち何れか一項に記載の方法。
- 予め定められた期間、少なくとも一つの検出閾値の変更を維持することを特徴とする先行請求項のうち何れか一項に記載の方法。
- 通常の該当オブジェクト用検出閾値から、高めに設定された検出閾値への、並びのその逆の切り替えに、ヒステリシスを採用することを特徴とする先行請求項のうち何れか一項に記載の方法。
- ガラス上での氷の存在確率の割出しに、少なくとも一つの、センサー手段内に内蔵された、温度センサーの温度シグナルを用いることを特徴とする請求項1〜7に係る少なくとも一つのセンサー手段のシグナル処理の適応方法に温度センサーを使用すること。
- 車両内のガラスの後ろに配置可能であり、温度センサーと、請求項1〜7のうち何れか一項に記載の方法が実装されているメモリー手段が内蔵されていることを特徴とするセンサー手段。
