PROBLEM TO BE SOLVED: To provide a tire position deciding system capable of accurately deciding a tire position.SOLUTION: A cycle calculation part 24 calculates an axle one rotation cycle based on axle rotation information (pulse counting value) of an axle rotation detection part 22 which represents a rotation state of an actual wheel even upon bad road travelling. Therein, a propriety judgement part 25 uses the axle one rotation cycle of which the reliability of information is high and confirms the propriety of gravity sampling conducted by a tire pneumatic pressure transmitter 4 based on the axle one rotation cycle, a gravity sampling interval time received from the tire pneumatic pressure transmitter 4 and the number of gravity sampling times of a specified value (target value). A position decision part 23 decides a tire position while taking into account a judgement result of the propriety judgement part 25.

    【課題】タイヤ位置をより正しく判定することができるタイヤ位置判定システムを提供する。【解決手段】周期算出部24は、たとえ悪路走行であろうと実際の輪の回転状態を表す車軸回転検出部22の車軸回転情報(パルス計数値)を基に車軸1回転周期を算出する。そして、妥当性判断部25は、情報の信頼性が高い車軸1回転周期を用い、この車軸1回転周期と、タイヤ空気圧送信機4から受信した重力サンプリング間隔時間と、規定値(狙い値)の重力サンプリング回数とを基に、タイヤ空気圧送信機4で実行された重力サンプリングの妥当性を確認する。位置判定部23は、妥当性判断部25の判断結果を踏まえ、タイヤ位置を判定する。【選択図】図1
