Abstract

Methods and systems for controlling a power source of a mobile machine having a continuously variable transmission (CVT) are disclosed. In one embodiment, the method includes receiving, from an operator of the mobile machine, input selecting of one of a plurality of target travel speeds of the mobile machine and input indicative of a requested output speed of the power source. The method further includes calculating a difference between the selected target travel speed and an actual travel speed of the mobile machine. Finally, the method includes adjusting the requested output speed of the power source based on the calculated travel speed difference, and commanding the power source based on the adjusted requested output speed of the power source.
