Beschreibung
Zusammenfassung:	The invention relates to a method of controlling a continuously variable transmission of a vehicle, the vehicle including an engine operative to drive the continuously variable transmission. According to the invention, the method includes: controlling a first clutch (50) of the continuously variable transmission of the vehicle by transmission control logic to an initial fixed position in a manual mode of operation, the continuously variable transmission including the first clutch (50), a second clutch (52), and a belt (54) coupled to the first and second clutches, the first clutch being adjustable to modulate a gear ratio of the continuously variable transmission, the first clutch of the continuously variable transmission in the manual mode of operation being adjustable between a plurality of discrete fixed positions based on shift requests initiated with a shift request device (55); receiving a shift request identifying a target fixed position of the first clutch of the continuously variable transmission; shifting the continuously variable transmission from the initial fixed position to the target fixed position; and initiating a torque reduction of the engine during the shifting to reduce a torque generated by the engine, wherein at least one of a magnitude and a duration of the torque reduction is adjustable based on an operator input device (111).
