ABSTRACT:
In a hybrid vehicle incorporating an internal combustion engine having an in-cylinder injector and a motor, when the temperature of the in-cylinder injector rises, if a current engine operation point is inside a prescribed intermediate load range (deposit risk range) where the temperature of the in-cylinder injector tends to rise, an engine load is increased or reduced while an engine speed is maintained, to thereby change the engine operation point to an engine operation point inside a low load range or to an engine point inside a high load range. A reduction or an increase in the engine output associated with the change of the engine operation point is compensated for by increasing or reducing the output of the motor. Thus, deposit accumulation in the in-cylinder injector is avoided.
