Description
a=v2/r
これは、一定な半径r(トランスポンダがリム3に設けられている場合)及び一定な速度vにおいて、遠心加速度aも同様に一定である(加速度推移8)ことを意味する。タイヤ接地長6の範囲では、タイヤ踏面2の内周面又は内側への取付けのため、遠心加速度7はセンサトランスポンダ1に作用しない。なぜならば、ここでは半径rが無限大になるからである。センサトランスポンダ1がタイヤ接地長6の範囲へ入ると、半径rがまず減少するので、ここで加速度がピークになる。同じことが、タイヤ接地長6の範囲からセンサトランスポンダ1が出る時にも当てはまる。
Claims (6)
- タイヤ接地長(6)を計算する方法であって、少なくとも1つの加速度センサを持つセンサトランスポンダ(1)がタイヤ(9)の踏面(2)の内側に設けられ、加速度センサの信号が閾値と比較されてディジタル化され、該ディジタル化された出力信号(13)が、該出力信号(13)の立ち上がりによってタイヤ接地面積で制御される積分回路(14)と、前記出力信号(13)の立ち上がりによって始動する別の積分回路(15)でそれぞれ積分され、前記積分回路(14) で積分された信号と、前記別の積分回路(15)で積分された信号との商を得ることで、速度に関係なくタイヤ接地長(6)の算定が行われる、方法。
- タイヤ接地長(6)からタイヤに特有なパラメータにより、タイヤ接地面積が計算されることを特徴とする、請求項1に記載の方法。
- タイヤ接地面積及びタイヤ圧力から車輪荷重が計算されることを特徴とする、請求項2に記載の方法。
- タイヤ(9)の踏面(2)の内側に取付けるためのセンサトランスポンダ(1)が、測定データをタイヤ(9)から受信装置へ伝達する装置、少なくとも1つの加速度センサ、タイヤに特有なパラメータ用のメモリ、及び請求項1〜3の1つに記載の方法によりタイヤ接地長(6)を計算する手段を持っている、センサトランスポンダ(1)。
- センサトランスポンダ(1)が少なくとも1つの圧力センサを持っていることを特徴とする、請求項4に記載のセンサトランスポンダ(1)。
- センサトランスポンダ(1)が少なくとも1つの温度センサを持っていることを特徴とする、請求項4又は5に記載のセンサトランスポンダ(1)。
