Patent ID: 7601093

Claim:
A vehicular drive control apparatus comprising: a first transmitting portion; a second transmitting portion; and at least one electric motor which is connected, so as to be able to transmit power, to a rotating element of the first transmitting portion or the second transmitting portion, the rotation speed of the rotating element changing as a shift in the first transmitting portion or the second transmitting portion progresses, wherein: in either of the first transmitting portion and the second transmitting portion, a change of engagement between engagement elements, provided for the first transmitting portion and the second transmitting portion, is performed by hydraulic control to make a shift progress, when a shift by the change of engagement between the engagement elements is performed in the first transmitting portion at the same time that a shift by the change of engagement between the engagement elements is performed in the second transmitting portion and the direction in which a gear ratio of the first transmitting portion changes is opposite the direction in which the gear ratio of the second transmitting portion changes, the at least one electric motor controls the shift in one or both of the first transmitting portion and the second transmitting portion such that the shift in one of the transmitting portions, from among the first transmitting portion and the second transmitting portion, ends while the shift in the other transmitting portion, from among the first transmitting portion and the second transmitting portion, is being performed; and if it is predicted that an inertia phase of the shift in the one transmitting portion will not end before an inertia phase of the shift in the other transmitting portion, an input rotation speed of the other transmitting portion is controlled by the electric motor, included in the at least one electric motor, that is connected to the rotating element of the other transmitting portion, to slow a progress of the shift in the other transmitting portion so that the inertia phase of the shift in the one transmitting portion ends before the inertia phase of the shift in the other transmitting portion.
