Abstract: A transmission assembly driven by an engine is disclosed. The transmission assembly includes a hydrostatic transmission having a variable displacement hydraulic pump and a hydraulic motor, a mechanical transmission coupled to the hydrostatic transmission for selecting a first gear range and a second gear range, and a controller for receiving operator inputs and generating a displacement command operable to control a displacement of the variable displacement pump. The controller determines the actual displacement. The controller determines a displacement shift level from the actual displacement. The controller executes a shift from the first gear range to the second gear range when the actual displacement reaches displacement shift level. A method of controlling a transmission assembly is also disclosed.

Abstract: A machine is described that includes an engine, a multi-clutch transmission and a controller. The controller is configured with computer-executable instructions for managing operation of the multi-clutch transmission to avoid autoengagement of a disengaged clutch. The computer-executable instructions configure the controller to receive sensor signals indicative of current operating status of the machine; determine, based upon the sensor signals, a configured minimum engine speed needed to avoid autoengagement of the disengaged clutch; and conditionally increase an engine speed based upon a comparison of the configured minimum engine speed and a sensed current engine speed. The machine includes a continuously variable transmission coupled to the multi-clutch transmission, and the controller is configured to adjust the continuously variable transmission ratio to counter the engine speed increase and thus maintain a current clutch output speed when increasing the engine speed to avoid autoengagement of a disengaged clutch.

Abstract: A system and method for variator control employs positively directed electronic make-up and flushing relief valves for more precise torque control of a hydraulic variator, especially during torque reversal, as well as improved cold weather operation. This can improve machine response during periods of severe torque change. The ability to more tightly control variator torque allows more precise torque management algorithms for power control and engine matching purposes. Moreover, the ability to positively control venting of the hydraulic circuit for purposes of fluid cooling allows for more consistent machine response regardless of ambient temperature.

Abstract: A system and method for optimizing machine performance using speed shaping in a machine having an engine and a drivetrain implementing engine underspeed module receives a throttle command requesting an increase in engine speed and transmits the throttle command to the engine. If the requested increase exceeds a predetermined function, the predetermined function is forwarded to the engine underspeed module as a speed standard. The engine underspeed module determines whether the actual engine speed attained by the engine is less than the speed standard by more than a predetermined gap value and, if so, reduces the power required by the drivetrain to avoid lugging of the engine.

Abstract: In one aspect of the present invention, an apparatus for controlling the negative load of an engine is disclosed. The engine is drivingly connected to a hydro-mechanical drive system that includes a variable displacement pump and motor. An engine speed sensor senses the rotational speed of the engine and produces an actual engine speed signal indicative of the rotational engine speed. A travel speed sensor senses the travel speed of the machine and produces an actual travel speed signal indicative of the machine travel speed. An overspeed controller compares the actual engine speed signal to a proportional and integral threshold, produces a proportional and integral error signal indicative of the difference between the actual engine speed signal magnitude and the corresponding thresholds, calculates a proportional and integral control signal from the corresponding errors, combines the proportional and integral control signals and responsively produces a command signal. A displacement controller receives the command signal and responsively controls one of the variable pump and motor to regulate the negative engine load to optimize the retarding power of the engine without overspeeding the engine or drivetrain.
