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.

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

The invention relates to power management of a off-highway vehicle. A power management apparatus is described as a vehicle control unit coupled to a vehicle and the vehicle control unit is in communication with an engine and a transmission controller. In response to power management input, the vehicle control unit sends a message to the transmission controller commanding a maximum torque limit based on the maximum drivetrain torque. The maximum torque limit is configured to optimize power to the vehicle implement.

A work machine including an internal combustion (IC) engine having an output, and an infinitely variable transmission (IVT) coupled with the IC engine output. The IVT includes an adjustable input/output (I/O) ratio. An operator adjustable torque control input device provides an output signal. At least one electrical processing circuit is coupled with the torque control input device and configured for controlling the IC engine output and/or the IVT I/O ratio, dependent upon the output signal from the torque control input device.

An efficient lubrication system for wet plate brake assemblies includes a flow control system that passes lubricant for cooling and lubrication through interdigitated wet brake plates when the plates are engaged. When the plates are disengaged, the wet plate assembly is controlled to limit its displacement by means of a pin and spring such that a gap is provided around the brake plates to provide a preferential path for lubricant, thus minimizing parasitic losses.

The hydraulically operated clutch elements of a powershift transmission have hold pressures which are calibrated by determining a parasitic drag time value represent a speed change of a clutch component due to a friction characteristic of the transmission, by calculating a target speed change value from the parasitic drag time valueas, and by deriving the clutch calibration values from the target speed change value.
