<p>A continuously variable transmission (4) shifts gears between a pair of pulleys (11, 12) via an endless torque transmission member (13) wound around the pair of pulleys (11, 12). A controller (22) performs a feedback control such that the actual transmission gear ratio between the pulleys (11, 12) follows a target transmission gear ratio (S6, S46). The controller (22) determines whether a stretch dependence transmission condition is satisfied, the aforementioned condition being a condition in which the presence or absence of a stretch in the endless torque transmission member (13) precludes the actual transmission gear ratio from reaching the target transmission gear ratio (S2, S3, S12, S13). When the stretch dependence transmission condition is satisfied, the controller (22) restricts the transmission gear ratio feedback control (S4, S24, S34).</p> |
