ABSTRACT:
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.
