Abstract
A control apparatus for a vehicle drive-force transmitting apparatus which establishes selectively a first state in which a drive force is transmitted by a gear mechanism and a second state in which the drive force is transmitted by a continuously-variable transmission mechanism. The control apparatus executes a shift-up action requiring the first state to be switched to the second state, in (a) a case in which a state of the drive-force transmitting apparatus satisfies a first condition that a gear ratio of the continuously-variable transmission mechanism is not lower than a first gear ratio value and in (b) a case in which the state of the drive-force transmitting apparatus satisfies a second condition that a lap-down control is executed with the gear ratio of the continuously-variable transmission mechanism being not lower than a second gear ratio value that is lower than the first gear ratio value.
