Beschreibung
Zusammenfassung:	A work machine (10) includes an internal combustion (IC) engine (12), and an infinitely variable transmission (IVT) (14) coupled with the IC engine (12). At least one sensor provides an output signal representing a real-time load value on the IC engine (12). At least one electrical processing circuit is configured for controlling an output of the IVT (14), dependent upon a threshold load value for the IC engine (12) and the real-time load value for the IC engine (12). In one embodiment, the at least one electrical processing circuit includes an engine control unit (ECU) (24) associated with the IC engine (12) , and a transmission control unit (TCU) (26) associated with the IVT (14). The ECU (24) provides an output signal to the TCU (26) representing the real-time load value. The TCU (26) controls the output of the IVT (14) dependent upon a comparison between the threshold load value and the real-time load value.
