When there is a requirement on switching from the electrically driven drive (EV) mode to the hybrid drive (HEV) mode by changing the accelerator position opening APO, the torque capacity tTc1 is generated for the first clutch (CL1) to start the engine. However, as tTc1 is at ²1, the engine rotational speed Ne is quickly increased to the high-speed region free of the influence of the compressive reactive force of the engine; once the engine rotational speed Ne becomes the high-speed region, the engine rotational speed is decreased as tTc1 and is at ²2. Consequently, it is possible to quickly pass through the low engine rotational speed region as the engine rotational speed torque is increased under the influence of the compressive reactive force, and avoiding the poor acceleration, as can be seen from the smooth variation of the time sequence increase of the transmission output rotational speed No as indicated by ²3, is possible.
