摘要:
A control apparatus for a vehicular drive system including an electrically controlled differential portion having a differential mechanism, and an electric motor which is operatively connected to the differential mechanism and an operating state of which is controlled to control a differential state between input and output shaft speeds, and a transmission portion constituting a part of a power transmitting path between the differential portion and a vehicle drive wheel, the control apparatus including a differential-state switching portion for switching the differential portion between differential-state and non-differential states, a shifting control portion for controlling a shifting action of the transmission portion, and a learning control portion for effecting learning compensation of a control amount of a control element to be controlled during the shifting action, wherein the learning control portion includes a differential-state learning control portion operable to implement the learning compensation of the control amount of the control element when the shifting action takes place in the differential state of the differential portion, and a non-differential-state learning control portion operable to implement the learning compensation when the shifting action takes place in the non-differential state of the differential portion, and the shifting control portion controls the shifting action in a presently selected one of the differential and non-differential states of the differential portion, on the basis of the learning compensation implemented by one of the differential-state and non-differential-state learning control portions which is operable in the other of the differential and non-differential states of the differential portion.
