Abstract
A continuously variable transmission control system is disclosed. The control system has a first operator input device to receive operator input and produce a corresponding first signal indicative of a selected one of a plurality of available predetermined discrete machine travel speed ranges. The control system also has a second operator input device to receive operator input and produce a corresponding second signal indicative of desired machine travel. The control system also has a power source operatively coupled to drive a continuously-variable transmission, and a controller configured to regulate at least one of an output of the power source and an output of the continuously variable transmission in response to the first and second signals such that an actual machine travel speed remains within the selected one of the plurality of predetermined discrete machine travel speed ranges.
