To provide a radio electric power reception system, a control method of a radio electric power reception system and a tire/wheel assembly, each of which allows for improvement in efficiency of electric power reception in radio electric power supply.SOLUTION: A radio electric power reception system 1 comprises: a tire/wheel assembly 3 constituted of a tire 10 and a wheel 20; an electric power receiving device 30 which is housed in the tire/wheel assembly 3, and receives electric power supplied by radio; a compressor 50 connected to the tire 10 in such a manner that the compressor 50 can supply air to tire 10; and a control device 60 that controls the compressor 50 to change inner pressure of the tire 10. The control device 60 determines whether or not the electric power receiving device 30 is at a position where the device can receive electric power by radio, and when determined that the inner pressure is first inner pressure, changes the inner pressure to second inner pressure lower than the first inner pressure when determining that the electric power receiving device 30 is at the position where the device can receive electric power by radio, and when the inner pressure is the second inner pressure, changes the inner pressure to the first inner pressure when determining that the electric power receiving device 30 is not at the position where the device can receive electric power by radio.SELECTED DRAWING: Figure 1

    【課題】無線給電における受電効率を向上させる、無線受電システム、無線受電システムの制御方法、及びタイヤ・ホイール組立体を提供する。【解決手段】無線受電システム1は、タイヤ10及びホイール20から成るタイヤ・ホイール組立体3と、タイヤ・ホイール組立体3に収容された、無線によって供給される電力を受け付ける受電装置30と、タイヤ10と通気可能に接続されたコンプレッサ50と、コンプレッサ50を制御してタイヤ10の内圧を変更する制御装置60と、を備える。制御装置60は、受電装置30が無線により受電可能な位置にあるか否かを判定し、内圧が第1の内圧である場合に、受電装置30が無線により受電可能な位置にあると判定すると、内圧を第1の内圧よりも低い第2の内圧に変更し、内圧が第2の内圧である場合に、受電装置30が無線により受電可能な位置にないと判定すると、内圧を第1の内圧に変更する。【選択図】図1
