Abstract:
A control apparatus for a vehicle drive-force transmitting apparatus including a continuously-variable transmission mechanism whose gear ratio is calculated based on a detected value of an input rotational speed of the transmission mechanism and a processed output-rotational-speed value that is a detected value of an output rotational speed of the transmission mechanism subjected to a filter processing. Updating the gear ratio of the transmission mechanism is inhibited (i) when the processed output-rotational-speed value is in a low rotational speed range with an absolute value of a rate of change of the processed output-rotational-speed value being not smaller than a given value, and also (ii) when the processed output-rotational-speed value is in the low rotational speed range with the absolute value of the rate of change of the processed output-rotational-speed value being smaller than the given value, if a certain operation that increases the absolute value is being executed.
