Abstract
A shift control apparatus for vehicular continuously variable transmissions is equipped with a related value calculating portion () that calculates a first driving force related value in association with an automatic shift mode in which an automatic shift control portion () performs shift control and that calculates a second driving force related value in association with a manual shift mode in which a manual shift control portion () performs shift control, and a second changeover portion (). The first driving force related value and the second driving force related value are set larger as the driving force output from an engine () increases. The second changeover portion makes a changeover from the manual shift mode to the automatic shift mode on the basis of a relationship between the first driving force related value and the second driving force related value.
