<p>A continuously variable transmission (4) shifts between a pair of pulleys (11, 12) via an endless torque transmission member (13) mounted on the pair of pulleys (11, 12). A controller (22) executes a feedback-control so that a real speed ratio between the pair of pulleys (11, 12) follows a target speed ratio (S6, S46). The controller (22) determines whether or not a elongation-affected shift condition, under which it is impossible for the real speed ratio to reach the target speed ratio depending on whether or not the endless torque transmission member (13) is elongated, holds (S2, S3, S12, S13), and limits a speed ratio feedback control when the elongation-affected shift condition holds (S4, S24, S34).</p> |
