ABSTRACT:
A control device for a vehicular drive system including continuously-variable transmission portion11and step-variable transmission portion20,wherein an emergency transmission control device is operated when one of the continuously-variable transmission portion11and step-variable transmission portion20fails to be normally operable, to change speed ratio of the other transmission portion such that overall speed ratio γT of the transmission mechanism10determined by the speed ratio γ0 of the continuously-variable transmission portion11and speed ratio γ of the step-variable transmission portion20is made equal to a value immediate before the above-indicated one transmission portion fails to be normally operable, so that a change of the overall speed ratio γT is reduced, whereby the vehicle can be run with high drivability.
