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.

Abstract: A machine powertrain having a transmission includes a control device responsive to selectively vary the transmission ratio in response to a shift signal. A lift sensor associated with a machine implement monitors an implement position and provides a lift signal. A ground speed sensor monitors the ground speed and provides a ground speed signal. A controller monitors the lift and ground speed signals, compares the lift signal to a predetermined position range, compares the ground speed signal to a predetermined ground speed range and, when the ground speed signal is within the predetermined ground speed range and the lift signal is within the predetermined position range, provides the shift signal causing the selectively variable ratio of the transmission to change.
