Abstract
A system for driving a machine is provided. A user input device inputs a desired throttle setting for the machine. The system includes an infinitely variable transmission having a transmission ratio that is adjustable. At least one sensor determines an inclination of the machine relative to a reference plane. A controller is configured to determine and apply a variable rate limit upon change in the transmission ratio based on the inclination of the machine when the desired throttle setting is reduced more than a predetermined amount and to adjust the rate limit based on the difference between an actual engine speed and a desired engine speed.
