Patent ID: 8571774

Claim:
A method of propelling a machine with a propulsion system having a prime mover operatively connected through a continuously variable transmission to a propulsion device, propulsion-system controls, and one or more other machine systems, the method comprising: transmitting power from the prime mover to the propulsion device with the continuously variable transmission while controlling a first operating parameter of the continuously variable transmission with the propulsion-system controls, including adjusting the first operating parameter based on operator input, determining a magnitude of an adjustment limit for the first operating parameter based on one or more second operating parameters of the one or more other systems of the machine, including determining the magnitude of the adjustment limit based at least in part on whether the machine is travelling in a forward direction or in a reverse direction, and applying the adjustment limit to the first operating parameter, wherein: the one or more other systems of the machine include a steering system; and determining the magnitude of the adjustment limit for the first operating parameter based on one or more second operating parameters of the one or more other systems of the machine includes determining the magnitude of the adjustment limit for the first operating parameter based on an operating parameter of the steering system.
