  • Patent number: 12590440
    Abstract: A power machine can include operator input devices and a control system configured to command movement of actuators based on operator inputs received from the operator input devices. Movement of one or more of the actuators can be commanded based on input at one or more of the operator input devices and a response curve selected from a plurality of different response curves. Movement of one or more of the actuators can be based on a selected control mode for the power machine that corresponds to a selected control-function mapping of the operator input devices to the one or more actuators. A lift arm can be variously controlled to execute automatic or other operations. An excavator can be operated in a sustained-speed travel mode.

  • Publication number: 20250283297
    Abstract: A power machine includes a lift arm structure including a boom, an arm pivotally coupled to the boom and a work implement pivotally coupled to the arm. The work implement is configured to grip a material. A work implement actuator is configured to pivot the work implement relative to the arm and apply pressure to the material. At least one sensor is configured to provide a measurement for calculating a position angle of the work implement relative to the arm. A controller is configured to maintain an optimal pressure on the work implement actuator based on the position angle of the work implement relative to the arm and based on a characteristic of the material.

  • Publication number: 20240416748
    Abstract: Disclosed embodiments include power machines or loaders, and systems used on loaders, configured to augment the control of the loader to accomplish repetitive tasks. Also disclosed are methods of learning a task for augmented control of a loader, and methods of controlling a loader to perform a learned task to provide augmented control of the loader.
