Abstract
A control device is configured to control an engine to be started and stopped such that when a hybrid vehicle is required to output a vehicular required power smaller than an engine starting threshold value the control device operates to stop the engine and use only a motor generator to cause the vehicle to travel and when the vehicular required power exceeds the threshold value the control device operates to start the engine and use both the engine and the motor generator to cause the vehicle to travel. The engine starting threshold value is set to be higher when at least one of an amount of lifting the intake valve and a working angle on the intake valve controlled by a VVL device provided to the engine is small than when at least one of the amount and the angle is large.
