Title
(JA) タイヤに含まれる複数のセンサデバイスからのデータ伝送を管理するための方法およびシステム
Abstract
(JA)

タイヤに含まれるセンサデバイスからの無線伝送は、タイヤに関連した受信ユニットまたは伝送調整器によって調整される。詳細には、全センサデバイスは、伝送に利用可能な全体的な時間ウィンドウを知っており、少なくともこの情報に基づいて、そのような時間ウィンドウ内にそのデータを伝送するための専用のタイムスロットを計算する。この調整した伝送によって、衝突および伝送エラーの確率を著しく低減し、伝送数を減少して、各センサデバイスにおいて利用可能な限られたバッテリー資源に適合することが可能となる。
