Abstract
A control device for a vehicle continuously variable transmissionincludes: final speed ratio setting means for setting an overall speed ratio of the continuously variable transmission mechanismand the subtransmission mechanismto 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 mechanismand the subtransmission mechanismsuch 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 mechanismfollowing a determination that the stagnation period will occur.
