Abstract
A control apparatus for a vehicle drive-force transmitting apparatus that defines (i) a first drive-force transmitting path established by engagement of a first engagement device controlled by an on-off solenoid valve and (ii) a second drive-force transmitting path established by engagement of a second engagement device controlled by a linear solenoid valve. A third engagement device, which is, as well as the first engagement device, disposed in the first drive-force transmitting path, is configured to transmit a drive force during a driving state of the vehicle and to cut off transmission of the drive force during a driven state of the vehicle. In a case in which the second drive-force transmitting path is to be established in place of the first drive-force transmitting path, the second engagement device is engaged when the first engagement device is engaged, and the first engagement device is released after an inertia phase is started.
