PROBLEM TO BE SOLVED: To provide a turbocharger control device capable of accurately detecting degradation of a turbocharger.SOLUTION: The present invention relates to a control device (26) for a turbocharger (17) for supplying compressed intake air to an internal combustion engine (1). The control device (26) includes: a storage unit (27) storing a map (33) in advance; a detection unit (28) detecting a characteristic parameter; a calculation unit (29) calculating efficiency &eegr; of the turbocharger (17) on the basis of the detected characteristic parameter; a determination unit (30) determining whether the turbocharger (17) degrades by comparing the detected characteristic parameter and the calculated efficiency &eegr; with the map (33); and a notification unit (31) notifying a user of a maintenance request. |
