Description
車両用検出システム1は、自動車等の車両2に設けられる。車両2は、図2に示すように、例えば車室2b内に前後方向に3列、左右方向に2又は3列に配列された複数の座席2aを備える。各座席2aには、シートベルト(不図示)と、当該シートベルトを固定するためのバックル25とが設けられる。車両用検出システム1は、車室2b内の複数の座席2aへの搭乗者の着座状態を判定し、一定の条件を満たさない場合には、着座している搭乗者に対して報知を行うものである。例えば、車両用検出システム1は、着座している搭乗者がシートベルトを装着していない場合、シートベルトの装着を促すように当該搭乗者に警告を行うものである。本実施形態の車両用検出システム1は、リーダ10と、複数の検出器20と、複数のバックルセンサ20Aとを備える。車両用検出システム1は、リーダ10と複数の検出器20との間、リーダ10と複数のバックルセンサ20Aとの間において、RFID(Radio Frequency Idntifier)による通信技術を用いて近距離無線通信を行う。
