Claims (1)
- 【特許請求の範囲】 1.電子制御系を備え、この電子制御系において車輪の回転状態が車輪センサに よって検出され、タイヤトレッド円周の差が補正係数によって決定される、車両 のための応急用車輪を迅速に認識する方法において、 − 各々の車輪について短時間補正係数(KZRn)と長時間補正係数(LZRn )が求められ、 − 短時間補正係数(KZRn)が30〜300msのオーダーの時間インター バルで、作業サイクル(クロック1)で測定された瞬時の補正係数の平均値を求 めることによって決定され、 − 長時間補正係数(LZRn)が5〜30秒(クロック2)のオーダーの時間 インターバルで、それぞれの車輪の短時間補正係数と長時間補正係数との差(DRn )の平均値を求めること(LMRn)によっておよびこの平均値を評価すること によって求められ、この場合、その都度平均値の部分値が長時間補正係数(LZRn )を適応させるために評価され、 − 特に車両エンジンを始動させた後その都度、規則的に繰り返される予め 定めた事象の後で、3個の車輪(KZvmin)の短時間補正係数が同時にほぼ等し いときに、第4の車輪の短時間補正係数が所定の最短時間インターバル(t)で 所定の範囲内の比較的に大きな値を採択するとき、そして第4の車輪の短時間補 正係数(KZvmin)が最短時間インターバルの間ほぼ一定であるときに、個々の 車輪の短時間補正係数(KZRn)が互いに比較され、長時間補正係数(LZRn) がそれぞれの車輪の短時間補正係数(KZRn)と一度だけ等しくなるかまたは近 づけられることを特徴とする方法。 2.補正係数を計算するための入力量として、最も遅い車輪速度(Vmin)がそ れぞれの車輪の車輪速度によって割られ、 3個の車輪の短時間補正係数が1.5%よりも小さく、第4の車輪の短時間 補正係数が8〜20%の範囲内にあり、所定の最短時間インターバルの間最大で ±1.5%だけ変化するときに、長時間補正係数と短時間補正係数が等しくなる ことを特徴とする請求項1記載の方法。 3.所定の最短時間インターバル(t)が1〜3秒、特に約1.5秒であること を特徴とする請求項2または3記載の方法。 4.短時間補正係数(KZRn)が50〜200msのオーダーの時間インターバ ル(クロック1)にわたって平均値を求めることによって決定されることを特徴 とする請求項1〜3のいずれか一つまたは複数に記載の方法。 5.短時間補正係数が次式 によって求められ、 ここで、 KZRn=車輪n(n=1〜4)の短時間補正係数、 N =平均値を求めるループまたはサイクルの数 Vmin =瞬時の最も遅い車輪速度 VRn =車輪nの瞬時の速度 C =定数 であることを特徴とする請求項1〜4のいずれか一つまたは複数に記載の方法 。 6.長時間補正係数(LZRn)が10〜20秒のオーダーの時間インターバル( クロック2)にわたって平均値を求めることによって決定されることを特徴とす る請求項1〜5のいずれか一つまたは複数に記載の方法。
