To provide a tire attachment position detection system which can automatically detect a wheel position to which a tire (sensor) is attached even if, in particular, transmission power is varied, or the reception sensitivity of a receiver is low on the basis of only a reception state of a radio signal which is transmitted from a transmitter, a tire attachment position detection method and a tire attachment position detection program.SOLUTION: A tire attachment position detection system measures first signal intensity being the intensity of a radio signal received by a first receiver (R1) at each transmitter, measures second signal intensity being the intensity of a radio signal received by a second receiver (R2) at each transmitter, and calculates an intensity ratio being a ratio using the first signal intensity and the second signal intensity at each transmitter. The tire attachment position detection system detects a wheel position to which a tire mounted with the transmitter is attached on the basis of the first signal intensity and the second signal intensity at each transmitter.SELECTED DRAWING: Figure 4
【課題】送信機から送信される無線信号の受信状態のみに基づいて、特に、送信電力のばらつき、または受信機の受信感度が低い場合でも、タイヤ(センサ)が装着される車輪位置を自動的に検出し得るタイヤ装着位置検出システム、タイヤ装着位置検出方法及びタイヤ装着位置検出プログラムを提供する。【解決手段】タイヤ装着位置検出システムは、第1受信機(R1)が受信した無線信号の強度である第1信号強度を、送信機毎に測定し、第2受信機(R2)が受信した無線信号の強度である第2信号強度を、送信機毎に測定し、第1信号強度と第2信号強度とを用いた比率である強度比を、送信機毎に演算する。タイヤ装着位置検出システムは、送信機毎の第1信号強度、第2信号強度及び強度比に基づいて、送信機が搭載されたタイヤが装着されている車輪位置を検出する。【選択図】図4
