Abstract
When a gear of a transmission for transmitting torque of a motor to a drive shaft is shifted while an accelerator is off or an accelerator pedal is slightly stepped on, an upper limit rotation speed is set using a fluctuation rate of a value smaller than a value when the gear is not shifted, a target rotation speed of an engine is set using this upper limit rotation speed, and control is carried out so that an engine is operated at the target rotation speed. By this arrangement, when the accelerator pedal is stepped on and a large torque demand is demanded, rise of the engine rotation speed is restricted, a portion used for raising the rotation speed in power outputted from the engine is made smaller, and a larger power can be outputted to the drive shaft.
