- 車体(5)に対してタイヤを備えた複数の車輪(4a〜4d)が取り付けられた車両(1)に適用されるタイヤ空気圧監視システムであって、
前記複数の車輪それぞれに設けられ、該複数の車輪それぞれのタイヤ空気圧を検出するセンシング部(21)と、前記タイヤ空気圧に関するデータを格納したフレームを作成して送信する第1制御部(22a)と、前記タイヤ空気圧に関するデータの送信を指示する指示コマンドを示すRF電波を受信するRF受信部(22cb)と、前記RF受信部が前記RF電波を受信可能な状態にさせる起動コマンドを示すLF電波を受信するLF受信部(22ca)と、を有するセンサ送受信機(2)と、
前記車体側に設けられ、前記センサ送受信機から送信されたフレームを受信する受信部(34b)と、受信した前記フレームに基づいて前記複数の車輪それぞれのタイヤ空気圧を検出する第2制御部(34c)と、前記LF電波を送信するLF送信部(34aa)と、前記RF電波を送信するRF送信部(34ab)と、を有する車体側システム(3)と、を備え、
前記第2制御部は、前記車両を発進させる際に操作される起動スイッチがオフからオンに切り替わったことを検出すると、前記LF送信部から前記LF電波を送信させたのち、所定期間内に前記RF送信部から前記RF電波を送信させ、
前記第1制御部は、前記LF受信部にて前記LF電波を受信すると、前記RF受信部を前記RF電波の受信可能な状態とし、前記LF電波の受信後に送信されてくる前記RF電波を前記RF受信部で受信して、該受信の応答として前記フレームの送信を行うようになっているタイヤ空気圧監視システム。 - 前記第2制御部は、前記複数の車輪それぞれに備えられた前記センサ送受信機ごとに異なるタイミングで、かつ、該センサ送受信機ごとの個別識別情報を含ませて前記RF電波を送信し、
前記第1制御部は、前記LF電波を受信すると、前記所定期間中、前記RF受信部を前記RF電波の受信可能な状態とし、前記RF電波に該第1送信部が備えられた前記センサ送受信機の前記個別識別情報が含まれていると、前記フレームの送信を行う請求項1に記載のタイヤ空気圧監視システム。 - 前記第1制御部は、前記所定期間として、前記第2制御部が前記複数の車輪に備えられたすべての前記センサ送受信機に対して前記RF電波を送信し終わるまでの期間中、前記RF受信部を前記RF電波の受信可能な状態とする請求項2に記載のタイヤ空気圧監視システム。
- 前記第1制御部は、前記所定期間として、前記第2制御部が前記複数の車輪に備えられた前記センサ送受信機それぞれに対して前記RF電波を送信するタイミングの際に前記RF受信部を前記RF電波の受信可能な状態とし、前記受信の応答として前記フレームを送信する期間中には前記RF受信部が前記RF電波の受信が行えない状態に戻す請求項2に記載のタイヤ空気圧監視システム。
