Abstract
A method is disclosed for providing different speed ranges for a speed pedal in a continuously variable transmission having a closed loop control. The method comprises the steps of monitoring the output speed of the continuously variable transmission, monitoring the position of the speed pedal relative to the transmission output speed, establishing a plurality of control maps each having the same travel distance of a speed pedal but different speed ranges, and selecting the desired speed range relating to one of the plurality of control maps. This enables the operator to select a speed range to fit the operation, such as, travelling from one location to another, maneuvering, or loading a truck.
