Abstract
A control device for a continuously variable transmission includes first, second, and third controllers. The first controller controls, in response to a first speed control request for controlling a traveling speed of a vehicle for a predetermined state, a gear ratio of the continuously variable transmission such that a rotational speed of a drive power source approaches a set rotational speed. The second controller controls, in response to a second speed control request issued while the first controller is controlling the gear ratio, the gear ratio based on the rotational speed and the gear ratio. The third controller changes, when the rotational speed changes as a result of the second controller controlling the gear ratio, torque of the drive power source based on torque and the rotational speed of the drive power source before the gear ratio is changed and a target rotational speed of the drive power source.
