Abstract
A control apparatus for a vehicle drive-force transmitting apparatus that defines first and second drive-force transmitting paths between input and output rotary members. The second drive-force transmitting path is established by engagement of a second engagement device. The control apparatus includes an operation-state determining portion configured to determine which one of a plurality of states is established as an operation state of the second engagement device, by determining whether a plurality of transition-completion conditions, each of which is required to determine that a transition of the operation state of the second engagement device to a corresponding one of the plurality of states from another of the plurality of states has been completed, are satisfied or not, based on (α) a state of a hydraulic control executed to control a hydraulic pressure supplied to the second engagement device and (β) a rotational speed difference of the second engagement device.
