Abstract: A control system for a powertrain in a machine includes a first sensor which generates a first signal indicative of a ground speed of the machine. The control system includes a second sensor which generates a second signal indicative of a load of an engine in the powertrain. The control system includes a third sensor which generates a third signal indicative of an operational state of the machine. The control system includes an input device which enables an operator to generate a request for a powertrain output. The control system further includes a controller in communication with the first sensor, the second sensor, the third sensor and the input device. The controller determines an engine speed command and a transmission output torque command to produce a powertrain output based at least on the first signal, the second signal and the third signal in response to the requested powertrain output.

Abstract: A control system for a powertrain system includes an electronic control unit structured to receive ground speed data and load factor data. The electronic control unit determines an engine speed command to an engine and a torque command to a variable-torque transmission based upon an engine speed limit and a torque scale factor that can vary with ground speed and load factor. The commands produce an economy output of the powertrain to reduce fuel consumption.
