PROBLEM TO BE SOLVED: To make it possible to accurately detect an abnormality of an attachment state of an onboard machine to a vehicle.SOLUTION: An onboard machine comprises: a vehicle-to-vehicle/road-to-vehicle communication unit 16b which receives an attachment state index that is transmitted from the peripheral vehicle by a vehicle-to-vehicle communication, and that has been determined on the basis of an output value from an illuminance sensor or the like that outputs the output value in response to an attachment state of an onboard machine to the peripheral vehicle; a reference-value setting unit 116b which sequentially sets reference values that serve as standards of attachment state indexes that have been received from a plurality of peripheral vehicles by the vehicle-to-vehicle/road-to-vehicle communication unit 16b, from the attachment state indexes; and a first abnormality detector 117b which compares one of the reference values set by the reference-value setting unit 116b with the attachment state index, which has been received by the vehicle-to-vehicle/road-to-vehicle communication unit 16b from the corresponding peripheral vehicle, for the onboard machine of the peripheral vehicle, thereby detecting an abnormality of the attachment state of the onboard machine to the peripheral vehicle.SELECTED DRAWING: Figure 3

    【課題】車載機の車両への取り付け状態の異常を精度良く検出することを可能にする。【解決手段】周辺車両から車車間通信によって送信されてくる、その周辺車両での車載機の取り付け状態に応じた出力値を出力する照度センサ等の出力値をもとに決定された取り付け状態指標を受信する車車/路車通信部16bと、車車/路車通信部16bで複数台の周辺車両から受信した取り付け状態指標から、取り付け状態指標の基準となる基準値を逐次設定する基準値設定部116bと、基準値設定部116bで設定した基準値と、周辺車両から車車/路車通信部16bで受信したその周辺車両の車載機についての取り付け状態指標とを比較することによって、その周辺車両での車載機の取り付け状態の異常を検出する第1異常検出部117bとを備える。【選択図】図3
