PROBLEM TO BE SOLVED: To provide a receiver of a tire air pressure monitoring system for providing an optimal low air pressure alarm threshold even under environment where ambient temperature changes.SOLUTION: At first, in winter, it is assumed that a reference point K1 at which tire air pressure is a low air pressure alarm threshold Th, and tire temperature is the tire temperature 'T winter' is set, and a low air pressure alarm threshold straight line L1 passing through the reference point K1 and having an inclination according to the Boyle-Charles' law is set. Then, in summer, a reference point K2 at which the tire air pressure is the low air pressure alarm threshold Th, and the tire temperature is the tire temperature 'T summer' is set, and a low air pressure alarm threshold straight line L2 passing through the reference point K2 and having the inclination according to the Boyle-Charles' law is reset.SELECTED DRAWING: Figure 2
【課題】周辺温度が変化した環境下でも最適な低空気圧警報閾値を提供することを可能にしたタイヤ空気圧監視システムの受信機を提供すること。【解決手段】当初、冬に、タイヤの空気圧が低空気圧警報閾値Thであって、タイヤの温度がタイヤの温度「T冬」である基準点K1が設定され、その基準点K1を通過するとともにボイルシャルルの法則に従った傾きを有する低空気圧警報閾値直線L1が設定されたとする。そして、夏には、タイヤの空気圧が低空気圧警報閾値Thであって、タイヤの温度がタイヤの温度「T夏」である基準点K2が設定され、その基準点K2を通過するとともにボイルシャルルの法則に従った傾きを有する低空気圧警報閾値直線L2が設定し直される。【選択図】図2
