Abstract
A control device for a continuously variable transmission performs transmission control so that an actual transmission control value becomes a target transmission control value. The control device includes a lead compensation unit, delay compensation unit, and a setting unit. The lead compensation unit performs lead compensation of the target transmission control value. The delay compensation unit performs delay compensation of the target transmission control value. The setting unit is configured to set as the target transmission control value a post-compensation target transmission control value for which compensation is performed by the lead compensation unit and the delay compensation unit according to at least one of an input side rotation speed of the continuously variable transmission, an input torque to a driven side rotation element of the continuously variable transmission, a transmission ratio of the continuously variable transmission, and a rate of change of the transmission ratio.
