PROBLEM TO BE SOLVED: To provide a tire condition monitoring device in which a receiver can receive a signal transmitted from a transmitter, with a simple circuit configuration even when a transmission time of the transmitter is shorter than a reception interval of the receiver, in a case where the transmitter installed to a tire and the receiver installed to a vehicle body operate intermittently, respectively.SOLUTION: Every time a period corresponding to one period Tr1 of intermittent reception processing on a vehicle side device passes, a transmission interval Tt1 of a notification signal is controlled so that a transmission time Tp1 of preamble of the notification signal is shifted to a direction of relatively delaying with respect to an execution time Tw1 of the reception processing. When the transmission time Tp1 of the preamble in the relative shift step, passes through a range of the execution time Tw1 of the reception processing, whole body of the transmission time Tp1 of the preamble is included in the range of the execution time Tw1 of the reception processing, by controlling the transmission interval Tt1 of the notification signal.SELECTED DRAWING: Figure 5

    【課題】タイヤに設置された送信機と車両本体に設置された受信機とがそれぞれ間欠的に動作する場合において、送信機の送信時間が受信機の受信間隔より短くても、簡易な回路構成で、送信機からの信号を受信機が確実に受信できるタイヤ状態監視装置を提供する。【解決手段】車両側装置における間欠的な受信処理の一周期Tr1に相当する時間が経過する度に、受信処理の実行時間Tw1に対して通知信号のプリアンブルの送信時間Tp1が相対的に遅れる方向へシフトするように、通知信号の送信間隔Tt1が制御される。また、この相対的なシフトの過程においてプリアンブルの送信時間Tp1が受信処理の実行時間Tw1の範囲を通過する際、プリアンブルの送信時間Tp1の全体が受信処理の実行時間Tw1の範囲内に含まれるように、通知信号の送信間隔Tt1が制御される。【選択図】図5
