- タイヤ(7)を備えた複数個の車輪(5a〜5d)それぞれに備えられ、前記複数個の車輪それぞれのタイヤ空気圧を示す検出信号を出力する圧力センサ(21a)および前記タイヤのトレッドの裏面に取り付けられて各車輪の径方向もしくは回転方向の加速度を示す検出信号を出力する加速度センサ(21b)を有するセンシング部(21)と、前記タイヤ空気圧を示す検出信号を信号処理して前記タイヤ空気圧に関するデータとして格納したフレームを作成する第1制御部(22)と、前記フレームを送信する電波送信部(23)とを有してなる送信機(2a〜2d)と、
車体側に備えられ、前記フレームを受信する電波受信部(32)と、受信した前記フレームに格納された前記タイヤ空気圧に関するデータに基づいて、タイヤ空気圧低下の発生を検出する第2制御部(33)とを有する受信機(3)とを備え、
前記第1制御部は、前記加速度センサの検出信号に基づいて、前記トレッドのうち前記加速度センサの設置場所と対応する場所である設置対応場所が路面に接地したときに発生する前記加速度の変化から車両が走行中であるか否かを判定し、前記車両が走行中であると判定したのち、前記加速度センサの検出信号が示す加速度の変化から前記設置対応場所が路面に接地したことを判定し、予め設定した期間内に前記設置対応場所が路面に接地したと判定されれば、前記設置対応場所が路面に接地した回数である路面接地回数が所定の閾値を超える毎に前記電波送信部より前記フレームの定期送信を行い、前記予め設定した期間内に前記設置対応場所が路面に接地したことが判定されなければ前記車両が停止したと判定して前記フレームの定期送信を行わないことを特徴とするタイヤ空気圧検出装置。 - 前記第1制御部は、前記加速度センサの検出信号が示す加速度の変化に基づいて車両が走行中であるか否かを判定し、前記車両が走行中であると判定されると、前記圧力センサによるタイヤ空気圧検出を行わせると共に、前記タイヤ空気圧に関するデータとして格納したフレームを作成して前記電波送信部より前記フレームの送信を行わせることを特徴とする請求項1に記載のタイヤ空気圧検出装置。
- 前記第1制御部は、前記車両が走行中と判定したのち、前記加速度センサの検出信号が示す加速度の変化から前記設置対応場所が路面に接地したことを判定し、連続する前記設置対応場所が路面に接地したと判定されたタイミングの間の時間間隔が予め設定した期間以内であれば前記フレームの定期送信を行い、前記期間を超えていれば前記車両が停止したと判定して前記フレームの定期送信を行わないことを特徴とする請求項1または2に記載のタイヤ空気圧検出装置。
