To provide a wheel position detection device capable of performing wheel position detection in a shorter time, and a tire air pressure monitoring system with the same.SOLUTION: Preferable timing suitable for frame transmission for wheel position detection is detected, and a TPMS-ECU 3 makes each transmitter 2 output a transmission command indicative of frame transmission at the preferable timing. Then the TPMS-ECU 3 receives an answer frame transmitted from a transmitter 2 in response to the transmission command, and performs wheel position detection on the basis of gear information on respective travel wheels 5a-5d at the reception timing.SELECTED DRAWING: Figure 1
【課題】より短時間で車輪位置検出を行うことが可能な車輪位置検出装置およびそれを備えたTPMSを提供する。【解決手段】車輪位置検出のためのフレーム送信を行うのに適した好適タイミングを検出し、その好適タイミングの際にTPMS−ECU3より各送信機2にフレーム送信を指示する送信コマンドを出力させる。そして、TPMS−ECU3にて、送信コマンドに応答して送信機2から送信された応答フレームを受信し、その受信タイミングでの各走行車輪5a〜5dの歯車情報に基づいて、車輪位置検出が行われるようにする。【選択図】図1
