ABSTRACT:
When shifts are performed at the same time in first and second transmitting portions and the gear ratios of those transmitting portions change in opposite directions, a simultaneous shift control unit controls the shift in the first transmitting portion using a first electric motor and controls the shift in the second transmitting portion using a second electric motor such that the shift in one transmitting portion, from among the first and second transmitting portions, ends while the shift in the other transmitting portion is being performed. The shifts in the two transmitting portions will not end at the same time so the amount of shift shock felt by an occupant can be reduced. Also, the shifts in the two transmitting portions are controlled by the first and second electric motors so the progress of the shifts in those transmitting portions can be actively adjusted.
