PROBLEM TO BE SOLVED: To provide a wheel fastening state determining device which can monitor a wheel fastening state during traveling, can easily attach/detach sensors to/from a vehicle, does not influenced on vehicle weight, axle width, and supporting stiffness so much, can determine an abnormal condition reducing an influence of a disturbance, can improve determination accuracy, and can quantify a determination reference.SOLUTION: A wheel fastening state determining device is equipped with a sensor unit 3 which can be attached/detached to/from a wheel fastening portion, and an information processing device 4 such as an on-vehicle apparatus 4A and a communication terminal 4B. The information processing device 4 has a measurement timing instructing portion 23 which reads vehicle state data from a control/communication system 5 of a vehicle, and instructs measurement to the sensor unit 3 at a fixed timing; and an information processing portion 24 which determines an abnormal condition of a fastening state of the wheel fastening portion by comparing measurement data with accumulated data measured and stored under the same condition in the past.SELECTED DRAWING: Figure 7

    【課題】走行中の車輪締結状態監視が可能で、センサ類の車両への着脱が容易であり、車両重量、車軸幅、支持剛性への影響が小さく、外乱による影響を低減した異常判定が可能で、判定精度の向上、判定基準の定量化が図れる車輪締結状態の判定装置を提供する。【解決手段】車輪締結部に着脱可能なセンサユニット3と、車載器4A,通信端末4B等の情報処理装置4とを備える。情報処理装置4は、車両の制御・通信系5から車両状態データを読み込み、定められたタイミングで前記センサユニット3に測定を指示する測定タイミング指示部23を有する。また、測定データを、過去に同一条件で測定して記憶した蓄積データと比較することで、車輪締結部の締結状態の異常を判定する情報処理部24を有する。【選択図】図7
