Summary: | To discriminate whether or not transmitted data is any one of right and left data without requiring setting change by manual input, even when positions of right and left tires are changed.SOLUTION: Right and left acceleration detection means 25 is fixed to each of right and left tires, detects a degree of acceleration when a tire outside surface is rotated in a predetermined one direction and accelerated as a positive value, and detects a degree of acceleration when being rotated in an opposite direction and accelerated as a negative value. Right and left transmission means 21 transmits tire state information in association with acceleration information indicating the degree of acceleration detected by the acceleration detection means 25 is positive or negative. When forward acceleration determination means 34 determines that the vehicle is in forward acceleration, tire position discrimination means 32 discriminates whether or not tire state information received by reception means 31 is tire state information transmitted from any of right and left transmission means 21 based on the information on the degree of acceleration in association with the tire state information.SELECTED DRAWING: Figure 3
【課題】左右のタイヤの位置変更等を行った場合であっても、送信されたデータが左右の何れのデータであるかを手入力による設定変更を要することなく判別可能にする。【解決手段】左右の加速度検出手段25は、左右のタイヤの各々に対して固定され、タイヤ外側面が所定の一方向に回転して加速した際の加速度を正の値として検出し、反対方向に回転して加速した際の加速度を負の値として検出する。左右の送信手段21は、タイヤ状態情報を、加速度検出手段25が検出した加速度が正負の何れであるかを示す加速度情報に関連付けて送信する。タイヤ位置判別手段32は、車両が前進加速中であると前進加速判定手段34が判定しているとき、受信手段31が受信したタイヤ状態情報が左右の送信手段21のうち何れから送信されたタイヤ状態情報であるかを、当該タイヤ状態情報に関連付けられた加速度情報に基づいて判別する。【選択図】図3 |
