  • Patent number: 12024173
    Abstract: A self-propelled work vehicle is provided with work state estimation and associated control techniques. The work vehicle comprises ground engaging units, a work implement configured for controllably working terrain, and various onboard sensors. A controller is functionally linked to at least the one or more onboard sensors and configured to ascertain a first parameter or operation of the work vehicle, determine a work state of the work vehicle, based at least in part on respective input signals from one or more onboard sensors, and generate a control signal for controlling at least a second parameter or operation of the work vehicle, responsive to the ascertained first parameter or operation and the determined work state. The control signals may be provided for proactive adjustments to engine speed, movements of the work implement, movements of the work vehicle itself, etc.

  • Publication number: 20230135150
    Abstract: One or more techniques and/or systems are disclosed for identifying field conditions of a field. Site conditions of a target site affecting machine sink can be identified using real-time or historical data. Soil conditions, weather conditions, moisture levels, and other factors may be used to determine whether a target site may result in machine sink of a target piece of equipment. The machine sink information can be identified for a target area, that comprises a target site, and a machine sink map can be generated for the site. Target equipment specifications can be used to determine whether the target equipment may effectively traverse the target site based on the machine sink map. Further, a travel path may be generated for a piece of target equipment based on the machine sink map, site conditions, and the equipment specifications.

  • Patent number: 11577796
    Abstract: A working machine includes an undercarriage, a main frame, a swing bearing supporting the undercarriage from the main frame, a swing motor configured to pivot the main frame on the swing bearing about a pivot axis, a boom extending from the main frame along a working direction, and a pivot angle sensor configured to provide a pivot angle signal corresponding to a pivot position of the main frame relative to the undercarriage about the pivot axis. A controller is configured to receive the pivot angle signal and to drive the swing motor automatically.

  • Patent number: 11457563
    Abstract: A controller for a harvester receives a speed of the harvester, the pitch, the yaw and the roll of the vehicle body, compares the sensed yaw, pitch and roll of the vehicle body to respective acceptable yaw, pitch and roll ranges. The controller also receives a conveyor position respect to the vehicle body, compares the conveyor position to an acceptable range of conveyor positions, calculates a center of gravity of the harvester based upon the yaw, pitch, roll and conveyor position, and compares the speed of the harvester to an acceptable range of speeds based upon the calculated center of gravity of the harvester. The controller also sends a signal to move the conveyor with respect to the vehicle body, alert the user to move the conveyor with respect to the vehicle body, reduce the speed of the harvester, or alert the user to reduce the speed of the harvester.

  • Publication number: 20220282460
    Abstract: A terrain-based travel assist system and method are provided for stability control in a self-propelled work vehicle such as an excavator comprising ground engaging units and at least one work implement configured for controllably working terrain. Upon selecting or determining a travel mode for the work vehicle, the respective predetermined target positions and/or operations of the at least one work implement are retrieved from data storage, corresponding to the determined travel mode. Feedback signals are received from sensors corresponding to respective current positions and/or operations of the at least one implement, and in some embodiments to a vehicle speed. Control signals are generated for automatically controlling the at least one work implement to the respective predetermined target positions and/or through the respective operations, responsive to the determined travel mode and the received feedback signals.
