Abstract
A control device includes an arrangement for deriving an input torque input to a belt-type continuously variable transmission based on a control amount of a first actuator. The continuously variable transmission includes a first actuator that is provided on a one movable sheave side, that presses the one movable sheave toward one fixed sheave, and that can generate a belt pinching pressure on the one movable sheave side, and a second actuator and a torque cam that are provided on the other movable sheave side, that press the other movable sheave toward the other fixed sheave, and that can generate a belt pinching pressure on the other movable sheave side.
