CONTROL DEVICE OF A CONTINUOUSLY VARIABLE TRANSMISSION

摘要

A low-side target gear ratio "alpha" and a high-side target gear ratio "beta" are calculated using an up-use map Ma and a down-use map Mb based on a vehicle speed and an accelerator opening amount, and with regard to a region wherein the target gear ratio "alpha" is not more "high" than an actual gear ratio and the target gear ratio "beta" is not more "low" than the actual gear ratio, a gear ratio of a continuously variable transmission is held.
