    Abstract: A control device for a vehicle continuously variable transmission 4 includes: final speed ratio setting means for setting an overall speed ratio of the continuously variable transmission mechanism 20 and the subtransmission mechanism 30 to be reached on the basis of an operating condition of the vehicle as a final speed ratio; shift control means for controlling the continuously variable transmission mechanism 20 and the subtransmission mechanism 30 such that the overall speed ratio aligns with the final speed ratio at a predetermined transient response; stagnation determining means for determining whether or not a stagnation period in which the overall speed ratio stops varying will occur during an upshift; and reduction control means for shortening a time required to advance to an inertia phase from a start of a shift in the subtransmission mechanism 30 following a determination that the stagnation period will occur.
