  • Patent number: 11555291
    Abstract: Systems and methods are disclosed herein for controlling cooling fans in a self-propelled work vehicle having a main frame supported by wheels or tracks. The cooling fans direct ambient air in accordance with at least one inlet in the main frame, and selectively operate in first and second opposing directions. A perception system is supported by the main frame and configured to provide perception data (e.g., perception data) corresponding to a field of vision which includes the at least one inlet and at least a portion of an associated working area. A controller obtains the perception data and automatically determines characteristics relating to contamination of the cooling system based at least On the perception data. The controller further generates output signals to the cooling fans based on at least one of the determined contaminant characteristics, for example a debris location, type, density, and/or quantity as relating to contamination of the cooling system.

  • Patent number: 10981763
    Abstract: In accordance with an example embodiment, a work vehicle may include a chassis, a linkage, a work tool, first and second actuators connected to linkage, one or more sensors, and a controller. The work tool is movably connected to the chassis by the linkage and pivotally connected to the linkage about a base axis. The work tool includes a tip positioned at a forward end of the work tool, with a tip axis parallel to the base axis and passing through the tip. The one or more sensors are configured to provide one or more signals indicative of at least one of a position, velocity, and acceleration of the work tool. The controller is configured to actuate, based on the one or more signals, the first actuator and the second actuator to level the work tool by rotating the work tool about the tip axis.
