Claims (5)
- 車両のタイヤ内に装着される測定値送信機と、車両本体に設けられるコントローラと、を備えるタイヤ情報検出装置であって、
前記測定値送信機は、アンテナと、前記アンテナに接続され前記コントローラとの間で送受信される信号の変復調を行う変復調器と、前記アンテナに接続された第1の結合コンデンサ及び第2の結合コンデンサと、前記第1の結合コンデンサに接続され、第1の圧電単結晶共振子及び圧力センサを有する第1の共振器と、前記第2の結合コンデンサに接続され、第2の圧電単結晶共振子及びコンデンサを有する第2の共振器と、を備え、
前記コントローラは、前記第1及び第2の共振器を共振させるための信号を送信する一方、前記第1の共振器の共振周波数の信号及び前記第2の共振器の共振周波数の信号を受信し、当該信号から抽出される前記第1及び第2の共振器の共振周波数差から環境変化の影響を取り除いた測定値を算出することを特徴とするタイヤ情報検出装置。 - 前記第1及び第2の圧電単結晶共振子の特性を近似させたことを特徴とする請求項1記載のタイヤ情報検出装置。
- 前記第1の圧電単結晶共振子及び前記第2の圧電単結晶共振子がそれぞれ第1の水晶共振子及び第2の水晶共振子であることを特徴とする請求項2記載のタイヤ情報検出装置。
- 前記第1及び第2の水晶共振子に用いられる水晶片を、単一のウェハーから製造したことを特徴とする請求項3記載のタイヤ情報検出装置。
- 前記測定値送信機は、第3の圧電単結晶共振子及びコンデンサを有しタイヤの温度の変化に応じて共振周波数が変化する第3の共振器を更に備え、前記第1の圧電単結晶共振子及び第2の圧電単結晶共振子の特性を近似させる一方、前記第3の圧電単結晶共振子の特性を前記第1の圧電単結晶共振子及び第2の圧電単結晶共振子の特性から相違させたことを特徴とする請求項1記載のタイヤ情報検出装置。
