Abstract
A shift control apparatus for a continuously variable transmission includes: a target transmission gear ratio setting section configured to set a target transmission gear ratio with reference to a map based on an accelerator opening degree and a vehicle speed; a shift control section configured to control a shift of the continuously variable transmission based on the target transmission gear ratio; and a downshift restricting section configured to judge whether or not a restriction of the downshift is needed based on at least one of a variation amount of the accelerator opening degree and an accelerator depression speed, and to perform the restriction of the downshift when the downshift restricting section judges that the restriction of the downshift is needed, irrespective of a variation of the accelerator opening degree inputted to the target transmission gear ratio setting section.
