Abstract
A control device for a continuously variable transmission performs feedback control so that an actual transmission control value becomes a target transmission control value. The control device for a continuously variable transmission includes a phase lead compensation unit configured to perform phase lead compensation of the feedback control, a phase delay compensation unit configured to perform phase delay compensation of the feedback control, and a phase compensation on/off determination unit configured to stop the phase delay compensation by the phase delay compensation unit when an unstable traveling state of a vehicle is detected, and to restore the phase delay compensation when a traveling state of the vehicle has changed.
