PROBLEM TO BE SOLVED: To provide a determination device of a wheel fastening state by which the wheel fastening state during traveling can be visually monitored, abnormality determination suppressed in an influence by a disturbance becomes possible by designating a vehicle traveling condition at measurement, determination accuracy is improved, a determination reference can be quantified, the determination accuracy can be further improved by accumulating a large capacity of information, and state determination becomes high in speed.SOLUTION: A determination device of a wheel fastening state comprises a sensor unit 3 which is attachable and detachable to/from a wheel fastening part, an information terminal 4 such as an on-vehicle apparatus 4A and a portable terminal 4B, and a server 30. The information terminal 4 has a measurement timing instruction part 23 which reads vehicle state data from a control/communication system 5 of a vehicle, and instructs the sensor unit 3 to measure the data at predetermined timing. The server 30 has an information processing part 32 which determines an abnormality of a fastening state of a wheel fastening part by comparing the measured data and accumulated data which have been measured in the past at the same condition, and are stored.SELECTED DRAWING: Figure 6
【課題】 走行中の車輪締結状態の監視が可能で、かつ測定時の車両走行条件指定により、外乱による影響を低減した異常判定が可能であり、判定精度の向上、判定基準の定量化が図れ、さらに大容量の情報蓄積によるさらなる判定精度の向上、状態判定の高速化が得ら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,携帯端末4B等の情報端末4と、サーバ30を備える。情報端末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。サーバ30は、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32を有する。【選択図】 図6
