Abstract
A method of controlling a pulley ratio of a continuously variable transmission vehicle, includes: sensing, by a controller, whether or not the position of a shift lever switches to a manual range, fixing, by the controller, a pulley ratio of a continuously variable transmission, when the position of the shift lever switches to the manual range, as a result of sensing, re-adjusting, by the controller, set pulley ratios of a plurality of manual shift positions based on the fixed pulley ratio of the continuously variable transmission, after the fixation, and controlling, by the controller, the continuously variable transmission at the re-adjusted pulley ratio of a target manual shift position, when manual shifting is required, after re-adjustment.
