  • Patent number: 12584297
    Abstract: A display system and method for a work machine having grade control is disclosed. The display includes a frame, an attachment coupled to the frame, a first sensor, a second sensor, and a controller. The first sensor is configured to generate a first sensor signal indicative of a frame angle relative to a direction of gravity. The second sensor is configured to generate a second sensor signal indicative of an attachment angle relative to one of the frame and the direction of gravity. The program instructions cause a processor on the controller to receive a first sensor signal, a second sensor signal, and a target grade input; determine a cross slope and a mainfall, and control a display device to display a singular graphic of the position of the attachment relative to the target grade.

  • Publication number: 20250347084
    Abstract: A work vehicle including a chassis, a ground-engaging mechanism, an input device, a global positioning system, and a controller. The input device providing a bench surface. The global positioning system configured to provide a chassis heading signal, a chassis inclination signal indicative of a main fall angle, and a chassis roll signal indicative of a cross slope angle. The controller configured to receive the chassis heading signals, record the chassis heading signal from a first location to a second location; use the recorded chassis heading signal as a reference chassis heading signal; receive a current chassis heading signal; determine an orientation error based on the reference chassis heading signal and the current chassis heading signal; and send a command to actuate the ground-engaging mechanism to shift the current heading to align with the reference heading based on the orientation error.

  • Patent number: 12385214
    Abstract: A work vehicle including a chassis, a ground-engaging implement, an input device, a global positioning system, an implement sensor, and a controller. The implement movably connected to the chassis via a linkage assembly configured to allow the implement to be raised, lowered, and moved in a roll direction. The input device providing a bench surface, a desired cross slope, a desired mainfall slope, and a desired depth. The global positioning system configured to provide a chassis heading signal, a chassis inclination signal indicative of a main fall angle, and a chassis roll signal indicative of a cross slope angle. The sensor configured to provide a blade inclination signal and a blade roll signal. The controller configured to receive the signals, determine a distance error, and send a command to move the implement toward the desired mainfall slope and cross slope based on the distance error and towards the desired depth.
