Abstract: A system and process for providing different levels of jerk in response to speed pedal displacement in a machine including a speed pedal having a range of displacement, a continuously variable transmission, a mechanism for measuring output speed of the continuously variable transmission, and an electronic controller for generating a jerk command signal that is in a one-to-one correspondence with the displacement of the speed pedal and shaping the jerk command signal into a velocity profile command that is applied to the continuously variable transmission and then comparing the output speed of the continuously variable transmission with the velocity profile command for controlling the continuously variable transmission.

Abstract: 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.

Abstract: A swing drive system for an upper structure of a machine includes an electric motor that receives electrical power and a torque command signal. A sensor provides a sensor signal indicative of a swing speed. An electronic controller provides the torque command signal to the electric motor in response to the command signal by receiving the command and sensor signals, providing the torque command signal to maintain a swing motion of the upper structure during a normal operating state, and providing the torque command signal based on the sensor signal to brake the swing motion at a substantially constant rate when the command signal is indicative of a zero desired swing speed during a braking operating state.

Abstract: A method of adjusting the operation of an engine-driven machine to avoid engine under-speeding entails converting a received speed or torque command into a power command. When an engine under-speed condition is sensed, the system performs underspeed correction in the power domain before converting the underspeed processed power command back into the units of the original domain. The converted underspeed processed power command is issued to the transmission or other component to alleviate the engine under-speeding condition.

Abstract: A system and method for controlling a variator operate to detect variator torques and/or internal pressures and generates a preliminary corrective command. The preliminary corrective command is transformed via a dynamic transform to account for system characteristics during transient operating conditions such as machine acceleration, such that the acceleration of the system during transient periods is not torque-limited by static torque-control map values. In an embodiment, the acceleration may be positive or negative, and in a further embodiment, braking is automatically applied in the case of negative requested power or desired machine retarding.

Abstract: A system and method for largely controlling transmission gear ratio oscillation is disclosed. When shifts are executed substantially at synchronous points rendering hysteretic anti-hunting schemes impractical, the disclosed techniques in any combination thereof may allow for oscillation control via an overridable lock-out timer. For oscillation control during incline navigation and other similar loading scenarios, the transmission may be selectively locked if certain operational criteria are met.

Abstract: 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.
