<p><P>PROBLEM TO BE SOLVED: To provide a control device of a vehicle drive device which can suppress sense of incongruity by suppressing engine rotation speed fluctuation when performing upshift of an automatic transmission. <P>SOLUTION: When a variable speed control means 70 makes the automatic transmission 12 upshift in an engagement state of a lock-up clutch 46, and when it is predicted that the lock-up clutch 46 is released after the upshift, a throttle opening control means 78 reduces the throttle opening even to an area in which an engagement state of the lock-up clutch 46 is maintained even after the upshift. Then, after reduction of the throttle opening, the upshift of the automatic transmission 12 is performed. Consequently, the lock-up clutch 46 can suppress driver's sense of incongruity, since it maintains the engagement state as it is before and after the upshift and it is avoided that the engine speed is fluctuated by release of the lock-up clutch 46 accompanying the upshift. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
