To accurately execute diagnosis on an abnormality sign of an instrument mounted on a vehicle.SOLUTION: A diagnostic apparatus 10 includes: a detection value acquisition unit for acquiring a detection value of a first instrument 30 mounted on a first vehicle 1-2 and 1-3; a validity value estimation unit for estimating a validity value of a detection value of a second instrument 30 mounted on a second vehicle 1-1 existing within a predetermined range from the first vehicle 1-2 and 1-3 using the detection value of the first instrument 30; and a diagnostic unit for diagnosing an operation state of the second instrument 30 by comparing the detection value of the second instrument 30 and the validity value of the detection value of the second instrument 30. The validity value estimation unit executes a first calculation that does not use weighting, or a second calculation that uses weighting, depending on the type of the first instrument 30.SELECTED DRAWING: Figure 1

    【課題】車両に搭載された機器の異常予兆の診断を精度良く行う。【解決手段】診断装置10は、第1車両1−2,1−3に搭載された第1機器30の検出値を取得する検出値取得部と、第1機器30の検出値を用いて、第1車両1−2,1−3から所定の範囲内に存在する第2車両1−1に搭載された第2機器30の検出値の妥当値を推定する妥当値推定部と、第2機器30の検出値、及び第2機器30の検出値の妥当値を比較することにより、第2機器30の動作状態を診断する診断部と、を備え、妥当値推定部は、第1機器30の種類に応じて、重みを用いない第1演算又は重みを用いる第2演算を行う。【選択図】図1
