<P>PROBLEM TO BE SOLVED: To provide a control device for automatic transmission, which can rapidly respond to an engine start request when it occurs during traveling of a vehicle, and hardly causes a shock according to the engine start. <P>SOLUTION: When the engine start request occurs during regenerative operation, a second brake B2 is released, and a motor generator MG is drive-controlled to normal rotation side, whereby the rotating speed of a third sun gear S3 in a second gear shift part 32 is reduced while maintaining the vehicle speed. Further, the engine 1 is started, whereby the rotating speed of a first ring gear R1 in a first gear shift part 31 is raised. Accordingly, the difference in rotating speed before and after a first clutch C1 is reduced, and when the difference in rotating speed is reduced to a predetermined value, engagement of the first clutch C1 is performed. <P>COPYRIGHT: (C)2011,JPO&INPIT |
