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.

Abstract: A system and method for controlling fluid flow through a hydraulic valve in a work machine is disclosed. The system and method may include receiving an input command by a controller configured to control a fluid flow to an actuator, the input command generated by an input controller. The system and method may also include receiving a parameter indicative of pump flow by the controller, determining a first valve command corresponding to the input command and determining a second valve command based upon the parameter that achieves the fluid flow to the actuator corresponding to the first valve command.
