Beschreibung
Zusammenfassung:	A work machine includes an IC engine having an output, an IVT having an input coupled with the IC engine output, and a ground speed actuator. A desired speed sensor associated with the ground speed actuator provides an output signal indicating a slower ground speed. At least one electrical processing circuit is configured for increasing an input/output (I/O) ratio of the IVT, dependent upon the sensor output signal, such that a net torque transfer back-driven from the IVT input to the IC engine output is substantially zero. Una máquina de trabajo que incluye un motor de combustión interna que tiene una salida, una transmisión infinitamente variable teniendo una entrada acoplada con la salida del motor de combustión interna, y un accionador de velocidad de tierra. Un sensor de velocidad deseada asociado con el accionador de velocidad de tierra proporciona una señal de salida indicando una velocidad de tierra más lenta. Por lo menos un circuito de procesamiento eléctrico está configurado para aumentar una proporción de entrada/salida de la transmisión infinitamente variable, dependiendo de la señal de salida del sensor, de manera que una transferencia de fuerza de torsión neta impulsa de regreso desde la entrada de la transmisión infinitamente variable a la salida de motor de combustión interna es esencialmente de cero.
