Abstract
2.1.公知の加速度センサでは、主感度軸と法線との間の位相角が、最高20°の範囲でのみ設定可能である。即ち加速度センサは、3つの空間軸に関して異なる特性を持ち、これが電子評価装置に高度の要求を課し、車両における使用を排除している。
2.2.多軸モノリシック加速度センサは次の特徴を持っている。
加速度センサが、共通な基板上に設けられてそれぞれ1つの主感度軸を持つ複数の個別センサから成り、各個別センサが、2つのねじりばね素子に回転運動可能に懸架され、かつ重心を有する地震質量を持ち、各個別センサが地震質量の偏向を測定する手段を持ち、加速度センサが少なくとも3つの同一な個別センサから成り、各個別センサが、その重心に対して偏心して懸架され、他の個別センサに対して、90°,180°又は270°回されている。
2.3.本発明は、車両において使用するため高級でオフセット安定な容量センサに特に適している。
(図1)
Description
位相角φは、各地震質量3の構成を介して、広い範囲にわたって設定される。同一の構造のため、すべての個別センサ2a〜2dにおいて位相角φは同じ大きさである。位相角φに対する適当な値は自由に設定可能である。理想的な場合として、直交座標系において45°の位相角φも設定可能である。この原理は一般化可能なので、個別センサ2a〜2dは異なる位相角を持つことができる。
