To provide a TPMS noise determination system capable of determining whether it is a noise even if each of an electric wave from a transmitter and an electric wave intensity is an approximation noise.SOLUTION: A TPMS noise determination system comprises: a transmitter installed to a tire held by a vehicle, and transmitting an electric wave of a predetermined time width; a receiver installed into the vehicle, and receiving the electric wave from the transmitter; and a determination part determining that the electric wave received by the receiver is a noise in the case where a time that intensity of the electric wave received by the receiver is equal to a threshold value or more exceeds a value obtained by multiplying a total amount of the transmitter held by the vehicle within the predetermined time width in which the transmitter transmits the electric wave.SELECTED DRAWING: Figure 3

    【課題】送信機からの電波と電波強度が近似のノイズであってもノイズであると判別可能なTPMSノイズ判定システムを提供する。【解決手段】TPMSノイズ判定システムは、車両が有するタイヤに設けられ、所定時間幅の電波を送信する送信機と、車両に設けられ、送信機からの電波を受信する受信機と、受信機が受信した電波の強度が閾値以上となった時間が、送信機が電波を送信する所定時間幅に車両が有する前記送信機の総数を乗じた値を超える場合に、受信機が受信した電波をノイズであると判定する判定部とを備える。【選択図】図3
