TIRE INTERNAL PRESSURE ADJUSTING DEVICE AND TIRE INTERNAL PRESSURE ADJUSTING METHOD

To provide a tire internal pressure adjusting device 10 and a tire internal pressure adjusting method capable of accurately obtaining a temperature of gas in a tire when charging the gas, and capable of executing internal pressure adjustment so as to obtain an optimum internal pressure value even if the temperature of the gas in the tire changes after charging the gas.SOLUTION: A tire internal pressure adjusting device 10 includes: a first flow channel through which gas in a tire is discharged; a temperature measuring part for measuring a first temperature, which is the temperature of the discharged gas in the first flow channel, by a temperature sensor disposed in the first flow channel; and a control part for calculating a target internal pressure, which is an internal pressure of the tire in a second temperature, to obtain a recommended internal pressure of the tire, which is a predetermined value, when the second temperature estimated from the first temperature as a predicted value of the temperature of the gas in the tire changes to the ambient temperature or a designated temperature, and outputting the target inner pressure.SELECTED DRAWING: Figure 1 【課題】開示の技術は、気体の充填時におけるタイヤ内の気体の温度を高精度に求めることを可能とし、これにより気体の充填後にタイヤ内の気体の温度が変化しても最適な内圧値となるような内圧調整を行うことが可能なタイヤ内圧調整用装置１０、及びタイヤ内圧調整用方法を提供することを目的とする。【解決手段】タイヤ内圧調整用装置１０は、タイヤ内の気体が放出される第１流路と、前記第１流路内に配置された温度センサにより、前記第１流路内における前記放出される気体の温度である第１温度を測定する温度測定部と、前記タイヤ内の気体の温度の予測値として前記第１温度から予測される第２温度が外気温度又は指定した温度に変化した場合に、予め定めた値である前記タイヤの推奨内圧になるように、前記第２温度における前記タイヤの内圧である目標内圧を算出し出力する制御部とを含む。【選択図】図１
