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.

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 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 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 predictive load management system includes a power source operable to generate power output, the power source having a desired operating range. A transmission having a drive member is operably engaged with the power source. A control system is in communication with the power source and the transmission. The control system receives at least one input indicative of a load on the transmission and identifies a change in the load on the transmission based on the at least one input. The control system is further operable to determine a desired power output of the power source to account for the change in the load on the transmission. The control system modifies a performance characteristic of the power source to cause the power source to generate the desired power output when the change in the load on the transmission will result in the power source operating outside of the desired operating range.

Abstract: A transmission assembly having a continuously variable transmission, a mechanical transmission coupled to the continuously variable transmission for selecting a first gear range and a second gear range, and a controller for receiving operator inputs and generating commands operable to control an output of the continuously variable transmission is disclosed. The controller executes a first shift between the first gear range and the second gear range at a shift point in response to the commands. The controller places the transmission in a first mode of operation whereby a second shift from the second gear range to the first gear range is inhibited. The controller places the transmission in a second mode of operation where the second shift from the second gear range to the first gear range is allowed when the output progresses beyond the shift point by a first value or the command falls past the shift point by a second value. The controller executes the second shift from the second gear range to the first gear range when the transmission is in the second mode of operation and the output reaches the output at the shift point. A method of controlling a transmission assembly is also disclosed.

Abstract: A transmission assembly includes a variable displacement hydraulic pump, a hydraulic motor operatively connected to the pump, a speed sensor operable to sense the speed of an output shaft of the motor, a first actuator for setting displacement of the pump in a positive displacement range in response to a first actuator command and a second actuator for setting displacement of the pump in a negative displacement range in response to a second actuator command. A controller is operable to transmit first actuator commands to the first actuator and transmit second actuator commands to the second actuator in response to operator inputs. The operator inputs require that the displacement of the pump to move from the positive displacement range to the negative displacement range. The controller generates first actuator commands which cause the first actuator to set the displacement to zero. The controller generates second actuator commands in response to the speed of the output shaft reaching a predetermined motor speed limit which cause the second actuator to set the displacement of the pump in the negative displacement region.
