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.

Abstract: The described system and method allow a controller to calibrate a transmission variator of a continuously variable transmission for torque control by obtaining static and dynamic qualities and parameters of the variator through an automated calibration procedure. The system and method employ a pair of transmission mode configurations and operational configurations in combination to obtain system-specific information. In this way, the system is able to calibrate out the system variations to provide effective feed forward torque control of the continuously variable transmission. In an embodiment, a first calibration operation is performed while the transmission is neutralized and a second calibration operation is performed while the transmission is engaged in a mode providing a fixed variator output speed.

Abstract: A method of modulating a boom assembly to perform in a linear manner. The boom assembly includes a boom and a stick. The method comprising the steps of sending at least one lever signal to a control device indicative of operator desired direction and desired velocity of the boom and the stick, calibrating the lever signals to provide a boom command signal and a stick command signal, applying an algorithm-to-the boom command signal and the stick command signal, which the algorithm uses command signal mapping, and providing a modulating factor to the control device as a result of the algorithm.
