Beschreibung
Zusammenfassung:	A control system and method for controlling a continuously variable transmission in a vehicle propulsion system includes measuring a speed ratio of the continuously variable transmission, determining whether the measured speed ratio is drifting away from a commanded speed ratio, and adjusting the commanded speed ratio to a value that is different than a desired speed ratio if the measured speed ratio is drifting away from the commanded speed ratio.
