ABSTRACT:
A work machine includes an internal combustion (IC) engine, and an infinitely variable transmission (IVT) coupled with the IC engine. The IVT includes an adjustable module and a mechanical module, with an adjustable input/output (I/O) ratio. A clutch is coupled with the mechanical module and has an output. An adjustable operator input device provides an output signal representing a power limit control. At least one electrical processing circuit is coupled with the operator input device and configured for controlling a selected combination of the I/O ratio and the clutch output, dependent upon the output signal from the operator input device.
