SOLUTION: Feedback control is performed to control first motor torque T M1 so that an engine rotational speed N E reaches a target engine rotational speed N E * . At the gear shifting of an automatic transmission part 20, since shifting feedback gain KP SFT for suppressing gear shift shock, which is uniformly made smaller than normal feedback gain KP NOR , is transitionally increased as a first motor rotational speed N M1 is close to an allowable limit of first motor rotational speed N M1LIM , first motor torque T M1 is increased and the engine rotational speed N E is changed toward the target engine rotational speed N E * so that the first motor rotational speed N M1 does not exceed the allowable limit of the first motor rotational speed N M1LIM . Thus, the excessive rotation of the first motor M1 is prevented. COPYRIGHT: (C)2010,JPO&INPIT
