  • Publication number: 20240147889
    Abstract: Systems and methods are provided for guidance and/or automation of work vehicles operating within defined work areas. The system may include a work vehicle controller. At least one boundary is determined with respect to the defined work area as being restricted for traverse by the work vehicle. Upon determining a current vehicle path will traverse a portion of the boundary, a revised vehicle path is automatically generated to avoid traverse of the boundary portion and further at least in part on vehicle motion characteristics such as an available minimum turn radius and/or a wheel angle rate of the work vehicle. Output signals are provided corresponding to the revised vehicle path, which may include for example control signals for automating an advance of the work vehicle along the revised vehicle path, or signals for generating a user interface visually guiding a vehicle operator with respect to the revised vehicle path.

  • Patent number: 11925132
    Abstract: Methods, apparatus, and articles of manufacture to generate acquisition paths are disclosed. An example apparatus includes input interface circuitry to obtain input data associated with a vehicle, threshold calculation circuitry to calculate, based on the input data, a threshold curvature and a threshold curvature rate of the vehicle, and acquisition path generation circuitry to select a point on a target path of the vehicle, generate an acquisition path from a current position of the vehicle to the point, the acquisition path including at least two curves, and cause storage of the acquisition path in response to the at least two curves satisfying the threshold curvature and the threshold curvature rate.
