Abstract
A control apparatus for a vehicle drive-force transmitting apparatus which includes a gear mechanism and a continuously-variable transmission mechanism and which establishes selectively a first state in which a drive force is transmitted by the gear mechanism and a second state in which the drive force is transmitted by the continuously-variable transmission mechanism. The control apparatus sets a shift-up-action permitted gear ratio of the continuously-variable transmission mechanism, which makes a state-switch-requiring shift-up action is permitted to be executed. When a running speed of the vehicle is not higher than a given value, a predetermined high gear ratio value is set as the shift-up-action permitted gear ratio. When the running speed is higher than the given value, a predetermined gear ratio range ranging from the predetermined high gear ratio value to a predetermined low gear ratio value is set as the shift-up-action permitted gear ratio.
