Abstract: A control device performs braking using a regenerative brake based on power generation in a motor generator in motor-driven traveling and performs a battery protecting process of starting an engine to set up transmission of a driving force between the motor generator and the engine using a clutch and performing braking based on an engine brake when a state of charge of a battery is equal to or greater than a threshold value in the motor-driven traveling. The control device sets a fuel-cutoff-permission rotation speed to a second rotation speed lower than a first rotation speed when the engine is started through the battery protecting process.

Abstract: In a case where a determination is made, after an engine is started based on a remote operation, that an ambient environment of a vehicle is not a predetermined appropriate environment based on a detection value from an ambient environment detection sensor configured to detect the ambient environment of the vehicle, the engine is stopped. As a result, it is possible to suppress a deterioration of an environmental state around the vehicle or an occupant cabin. As a result, it is possible to take more appropriate measures when the engine is started based on the remote operation.

Abstract: An electronic control unit is used for an internal combustion engine that executes a specific-cylinder fuel cutoff process in which combustion in part of cylinders is stopped and combustion is continued in the remaining cylinders. The electronic control unit diagnoses whether there is a misfire anomaly in the internal combustion engine based on a misfire frequency of the internal combustion engine. The electronic control unit executes a normality restoration diagnosing process of diagnosing, in a state in which it is diagnosed that there is a misfire anomaly, that the misfire anomaly has been resolved when a measured value of the misfire frequency becomes less than or equal to a specified normality restoration determination value. The normality restoration diagnosing process is configured to not diagnose, during the execution of the specific-cylinder fuel cutoff process, that the misfire anomaly has been eliminated.
