摘要： 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.

摘要： A hydraulic motor system for improved frequency response includes a hydraulic variator having a pump and a motor, wherein the pump includes a variable angle swash plate, and the system further includes an electric actuator for controlling an angle or torque of the swash plate, thereby controlling the motor output characteristics. The electric actuator for controlling the variable angle swash plate may comprise a linear electric motor, ball screw drive or a rotary electric motor. In an example, the rotary electric motor tilts the swash plate by applying a torque to the swash plate at a point away from its tilt axis. In a further example, the rotary electric motor tilts the swash plate via a worm drive or ball screw drive.

摘要： 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.

摘要： A variator torque control system adjusts a variator output so that the actual output torque of the variator closely matches an expected output torque. In an example, pressure values of an existing torque control map are supplemented in real time with calculated pressure supplement values based on the current operation of the variator. The pressure supplement value for each mapped pressure value may be derived based on a prior application of the same or another map value.

摘要： A transmission assembly is disclosed. The transmission assembly includes a continuously variable transmission driven by an input shaft at an input speed, a mechanical transmission coupled to the continuously variable transmission for selecting a first gear range and a second gear range, an output shaft driven by the mechanical transmission at an output speed, and controller operable to receive a speed command and generate a transmission ratio is command which control a ratio of the output speed to the input speed, and generate a shift command which causes the mechanical transmission to shift from the first gear range to the second gear range. An upper transmission ratio limit defined by an engine lug limit. A lower transmission ratio limit is defined by an engine overspeed limit. The controller causes the transmission to execute a shift from the first gear range to the second gear range which causes an instantaneous change in output speed. The engine lug limit or the engine overspeed limit are adjusted to inhibit a subsequent shift from the second gear range to the first gear range. A method for controlling a transmission assembly is also disclosed.
