Abstract:
1. A continuously-variable-transmission control device comprising: a V-belt continuously variable transmission including first and second sheave shafts, first and second sheaves rotating with the first and second sheave shafts, and a V-belt wound around the first and second sheaves; an actuator that changes a change gear ratio of the V-belt continuously variable transmission by changing a position of the first or second sheave; a control device that controls a drive of the actuator; a belt-width calculation unit that calculates a width of the V-belt during idling; a storage unit that stores the calculated belt width; a correction unit that corrects a driving state of the actuator controlled by the control device, on the basis of the belt width stored in the storage unit, wherein; the actuator changes the position of the first or second sheave to a target position; the correction unit corrects the target position of the actuator; and the control device controls the drive of the actuator so that the first or second sheave reaches the corrected target position.
