Abstract
A ratio change control for a transmission, in which an increase in feedback control term is restrained when a gearing mechanism takes over a drive between an input shaft, and an output shaft or when a transition in drive from the gearing mechanism to a continuously variable transmission mechanism has not been completed. Specifically, the feedback control term is set to zero.
