Abstract
A method for controlling a continuously variable transmission installed in a vehicle. The method utilizes a changing rate for varying an RPM ratio between an output shaft and an input shaft to permit rapid acceleration of a vehicle when needed as well as fuel consumption efficiency. The rate of changing the RPM ratio is a function of the actual velocity of the vehicle and a difference between the desired RPM of a driving pulley and an actual RPM of a driving pulley.
