Abstract
Description
Claims (8)
- 1.各タイヤについて読みとられた温度の測定値を少なくとも1つ送り出し各タ イヤ内に含まれている空気の量の推定量を計算する車両のタイヤ監視システム内 で信号を利用する方法において、 −少なくとも車両と地面の結合を確保する各タイヤについてほぼ同時点で読みと られた温度を含むデータ系列を設定すること、−読取られた温度のデータ系列の 中の最高温度と最低温度の間の偏差を計算すると、 −前記偏差が予め定められた閾値より小さい場合、各タイヤについてタイヤ内に 含まれている空気の量の推定量を必要な最小とみなされる値と比較すること、 −これらの推定量の1つが前記最小値より小さい場合、警報を起動させること、 を特徴とする方法。
- 2.前記必要最小値か、考慮対象のタイヤの温度の関数あることを特徴とする、 請求の範囲第1項に記載の方法。
- 3.空気の量の推定量が絶対圧力を絶対温度で除した比から成ることを特徴とす る請求の範囲第1項に記載の方法。
- 4.空気の量の推定量が絶対圧力によって構成されていることを特徴とする、請 求の範囲第1項に記載の方法。
- 5.車岡の各発進時点で実行されることを特徴とする、請求の範囲第1項乃至第 4項のいずれか1項に記載の方法。
- 6.非常用ホイールについて同じ時点で読取られた温度が各タイヤについて読取 られた温度のデータ系列の中に内含されていることを特徴とする、請求の範囲第 1項乃至第5項のいずれか1項に記載の方法。
- 7.前記温度データ系列に、車両上に配置されこセンサーによって同時点に読取 られた温度が付加できることを特徴とする、請求の範囲第1項乃至第5項のいず れか1項に記載の方法。
- 8.最小とみなされた前記値が、最後の膨張日に導入された空気量に応じて、及 び最後の膨張以降経過した時間及び正常とみなされた自然の空気抜け率に応じて 設定されることを特徴とする、請求の範囲第1項乃至第7項のいずれか1項に記 載の方法。
