To provide a tire auto-location system and a tire auto-location method which can save electric power of a power supply of a tire communication instrument.SOLUTION: A first processing part 28 makes tire communication instruments 4 respectively execute peak detection using output of an acceleration detecting part 11 that rotates in synchronization with a tire 3, by transmitting trigger radio waves Str for position determination, from an initiator 6 in which ranges where radio waves reach are different between axle units to the tire communication instruments 4. A second processing part 29 obtains measurement information Sk measured based on timings of reception of the trigger radio waves Str and of the peak detection in the tire communication instruments 4, by radio communication from each of the tire communication instruments 4. A third processing part 30 determines coordination of the axles 24 arranged in a longitudinal direction of a vehicle body with each of the tire communication instruments 4, on the basis of the measurement information Sk obtained from each of the tire communication instruments 4.SELECTED DRAWING: Figure 1

    【課題】タイヤ通信機の電源を省電力化できるタイヤオートロケーションシステム及びタイヤオートロケーション方法を提供する。【解決手段】第1処理部28は、車軸単位で電波の届く範囲が異なるイニシエータ6から、位置判定のトリガ電波Strをタイヤ通信機4に送信することにより、タイヤ3と同期回転する加速度検出部11の出力を用いたピーク検出を、各々のタイヤ通信機4に実行させる。第2処理部29は、タイヤ通信機4においてトリガ電波Strの受信とピーク検出のタイミングとに基づき計測された計測情報Skを、タイヤ通信機4の各々から無線によって取得する。第3処理部30は、タイヤ通信機4の各々から取得した計測情報Skに基づき、タイヤ通信機4の各々と車体前後方向に並ぶ車軸24との対応付けを判定する。【選択図】図1
