Patent ID: 8631641

Claim:
A control device for a vehicle, the control device being applied to a vehicle that comprises an internal combustion engine, an injector that directly injects fuel into a combustion chamber of the internal combustion engine, and a catalyst disposed in an exhaust passage of the internal combustion engine, the control device performing catalyst warm-up control on the catalyst, and the control device comprising: an electronic control unit, including executable program logic, configured to perform: determining whether a warm-up control required condition is met; recognizing a parameter indicating an amount of fuel diluted in oil, contained in engine oil diluted by fuel; recognizing a parameter indicating a temperature of the engine oil; and controlling execution/prohibition of the catalyst warm-up control, wherein when the warm-up control required condition is met, the electronic control unit determines whether the parameter indicating the amount of fuel diluted in oil is less than a determination value, and whether the parameter indicating the temperature of the engine oil is less than a determination value, wherein the electronic control unit executes the catalyst warm-up control if the parameter indicating the amount of fuel diluted in oil is less than the determination value, or if the parameter indicating the temperature of the engine oil is less than the determination value, and wherein the electronic control unit prohibits the catalyst warm-up control if the parameter indicating the amount of fuel diluted in oil is greater than or equal to the determination value, and the parameter indicating the temperature of the engine oil is greater than or equal to the determination value.
