Abstract: A method of operating a construction machine (10), which comprises a superstructure (100) and an undercarriage (200) rotatably coupled thereto. The method comprises retrieving (SI) a trigger signal (T) at a predetermined relative angle (a) between the superstructure (100) and the undercarriage (200) while operating the machine (10); retrieving (S2) an absolute angle (β) of the superstructure (100). The method also comprises calculating (S3) a current relative angle (γ) between the superstructure (100) and the undercarriage (200) on the basis of the trigger signal (T) and the absolute angle (β).

Abstract: A control may obtain first data related to a plurality of positions of an implement of a work machine during a first time period and may determine, based on the first data, a first noise value related to at least one velocity of the implement for the first time period. The control device may obtain second data related to a plurality of positions of the implement during a second time period and may determine, based on the second data, a second noise value related to at least one velocity of the implement for the second time period. The control device may determine, based on the first noise value and the second noise value, a start of motion of the implement. The control device may cause, based on determining the start of motion of the implement, the implement to be calibrated.

Abstract: According to a method, data related to at least one position of an implement (116) of a work machine (100) that has moved to a set position is obtained. One or more first noise amplitudes associated with the data are identified and, based on the one or more first noise amplitudes, a noise band related to the implement vibrating at the set position is determined. One or more second noise amplitudes associated with the data are identified and, based on the noise band and the one or more second noise amplitudes, it is determined that the implement has settled at the set position. Based on determining that the implement has settled at the set position, the implement is allowed to move to another position.

Abstract: Described herein are systems, methods, and other techniques for determining a period during which an implement of a construction machine is interacting with a ground surface. A vibration signal that is indicative of a movement of the implement is captured. One or more features are extracted from the vibration signal. The one or more features are provided to a machine-learning model to generate a model output. An implement-on-ground (IOG) start time and an IOG end time are predicted based on the model output, the IOG start time and the IOG end time forming the period.

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. Actuation of a bucket or other implement can be implemented based on signals from a material sensor.
