PROBLEM TO BE SOLVED: To provide a control device for a hybrid vehicle enabling easy detection of drag failure when a clutch is disengaged.SOLUTION: A control device for a hybrid vehicle includes: an engine 2 for transmitting power to a driving wheel 8 of the vehicle 1; a clutch 9 interposed in a power transmission path between the engine 2 and the driving wheel 8; an electric motor 3 that is disposed on the driving wheel 8 side of the clutch 9 in the power transmission path and transmits power to the driving wheel 8; a power generator 4 that is disposed on the engine 2 side of the clutch 9 in the power transmission path and generates electric power by using the power of the engine 2; engine torque estimation means for estimating engine torque of the engine 2; power generator torque estimation means for estimating power generator torque of the power generator 4; and failure detection means 13 for detecting drag failure of the clutch 9 on the basis of a difference between the engine torque and the power generator torque estimated by estimation means 11 when the clutch 9 is disengaged. |
