A control device for a continuously variable transmission that steplessly changes a speed ratio of the continuously variable transmission mounted on a vehicle, the control device including a controller that changes the speed ratio such that a stepwise upshift is performed, wherein in the case where an accelerator depression amount is constant, the controller increases a number of allowable stepwise upshifts as the accelerator depression amount is larger.

Control device and control method for continuously variable transmission

A control device for a continuously variable transmission, which sets a target input rotational speed, or a target value of an input rotational speed of the continuously variable transmission mounted on a vehicle, such that a speed ratio is changed in a stepped manner and which controls the continuously variable transmission such that the input rotational speed becomes equal to the target input rotational speed.
