<P>PROBLEM TO BE SOLVED: To appropriately reduce a shock at the time of switching a power engagement/disengagement means for engaging and disengaging power transmission between an engine and an electric motor from a disengaged state to an engaged state by a simple technology. <P>SOLUTION: When a request to switch the power engagement/disengagement means 6 from the disengaged state to the engaged state is generated, the output torque of the engine 1 is controlled according to the rotation speed difference between the rotation speed of an engine side rotation component 6a of the power engagement/disengagement means 6 and the rotation speed of a motor side rotation component 6b so that the former rotation speed may be closer to the latter rotation speed. The output torque of the engine 1 is gradually changed according to the range of the rotation speed difference. When the rotation speeds of both the rotation components 6a, 6b become almost the same, the supply of pressure oil from an oil pressure device 8 to the power engagement/disengagement means 6 is started so that the power engagement/disengagement means 6 may be switched from the disengaged state to the engaged state. When oil pressure reaches set pressure or higher and an oil pressure switch 14 is set to be turned on, each output torque of the engine 1 and the motor 2 is controlled to maintain the vehicle speed constant. <P>COPYRIGHT: (C)2008,JPO&INPIT |
