PROBLEM TO BE SOLVED: To provide a tire air pressure detection system, a vehicle body side device, and a tire side device, which can detect each air pressure by accurately identifying each tire.SOLUTION: A tire side device includes: a first storage section which stores the identifier for identifying an own device; a reception intensity measurement section which measures reception intensity of each measurement signal; a specification section which specifies the number of the measurement signals which can be received; and a second storage section which stores the number of the measurement signals in the measurement signals successively transmitted from a vehicle body side device to tire side devices corresponding to a plurality of tires and a reception order for receiving the measurement signal having the strongest reception intensity in the measurement signals which can be received. A response signal including information indicating the number of the measurement signals and the reception order, which are stored in the second storage section, and the identifier is transmitted to the vehicle body side device. In the vehicle body side device, a measure is determined on the basis of comparison with information indicating the number of the measurement signals and the reception order transmitted from the plurality of tire side devices.SELECTED DRAWING: Figure 5

    【課題】正確に各タイヤを識別して夫々の空気圧を検出することができるタイヤ空気圧検出システム、車体側装置及びタイヤ側装置を提供する。【解決手段】タイヤ側装置は、自装置を識別する識別子を記憶する第1記憶部と、測定用信号夫々の受信強度を測定する受信強度測定部と、受信できた測定用信号数を特定する特定部と、車体側装置から複数のタイヤに対応するタイヤ側装置宛てに順次送信される測定用信号の内の前記測定用信号数、及び受信できた測定用信号の内の最も受信強度が強い測定用信号を受信した受信順序を記憶する第2記憶部と、該第2記憶部に記憶した測定用信号数及び受信順序を示す情報及び識別子を含む応答信号を車体側装置向けに送信させ、車体側装置で複数のタイヤ側装置から送信された測定用信号数及び受信順序を示す情報の比較に基づき対応を決定する。【選択図】図5
