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 |
