In this regard, an in-vehicle control device includes: a requested torque calculation unit which calculates a requested torque on the basis of a driving state of a vehicle; a requested torque change amount calculation unit which calculates the amount of change in requested torque per unit time as a requested torque change amount; an estimated generation torque calculation unit which calculates estimated generation torque estimated as being generated by an engine ; an estimated generation torque change amount calculation unit which calculates the amount of change in estimated generation torque per unit time as an estimated generation torque change amount; and an abnormality detection unit which detects an abnormality of the engine on the basis of the integrated value of a difference between the requested torque change amount and the estimated generation torque change amount, and outputs abnormality determination for the engine",
