Beschreibung
Zusammenfassung:	A control apparatus for a vehicle drive-force transmitting apparatus including a gear mechanism and a continuously-variable transmission mechanism provided in respective first and second drive-force transmitting paths. The control apparatus sets a target gear ratio of the continuously-variable transmission mechanism during a switching control operation that is executed to switch between (i) a first state in which the first drive-force transmitting path is established and (ii) a second state in which the second drive-force transmitting path is established, such that, when drive wheels are not being slipped, the target gear ratio is set to a highest gear ratio of the continuously-variable transmission mechanism, and such that, when the drive wheels are being slipped, the target gear ratio is set to an actual gear ratio at a point of time at which the drive wheels start being slipped.
