  • Patent number: 11926992
    Abstract: A pilot neutralizing system of a work vehicle may include a pilot neutralizer and a flow control apparatus. The work vehicle may include a frame assembly and an actuating assembly to pivot the frame assembly. The pilot neutralizer is hydraulically coupled between an operator control member and a steering valve to selectively direct a pilot signal to the steering valve and is hydraulically coupled to a reservoir via a reservoir line. The pilot signal is used to switch the steering valve to change a direction of a hydraulic fluid flowing from the steering valve to the actuating assembly. The flow control apparatus is hydraulically coupled to the reservoir line and used to change a draining rate of the pilot signal to the reservoir. When the articulation position reaches a cushion region during steering, the pilot signal drains back through the flow control apparatus to the reservoir.

  • Patent number: 11927459
    Abstract: One or more information maps are obtained by an agricultural work machine. The one or more information maps map one or more agricultural characteristic values at different geographic locations of a field. An in-situ sensor on the agricultural work machine senses an agricultural characteristic as the agricultural work machine moves through the field. A predictive map generator generates a predictive map that predicts a predictive agricultural characteristic at different locations in the field based on a relationship between the values in the one or more information maps and the agricultural characteristic sensed by the in-situ sensor. The predictive map can be output and used in automated machine control.

  • Patent number: 11919585
    Abstract: A track tension system including a hydraulic cylinder coupled between a drive frame and idler of a track system, an accumulator and a hydraulic valve that controls flow between the cylinder and accumulator. The cylinder extends and retracts to change the distance between the drive frame and idler which increases and decreases, respectively, tension on the track system. The hydraulic valve can be opened to allow flow between the cylinder and accumulator, and closed to block flow between the cylinder and accumulator. Control factors can be monitored to control valve position. An overload pressure relief can allow flow between the cylinder and accumulator when the hydraulic valve is closed and pressure in the cylinder reaches overload pressure. An orifice can allow constricted flow between the cylinder and accumulator when the hydraulic valve is closed. A check valve can connect the track tension system to a vehicle hydraulic system.

  • Patent number: 11906974
    Abstract: An autonomous off-road vehicle, upon encountering an obstruction while navigating a route, can apply a first machine-learned model to identify the obstruction. In the event that the first machine-learned model cannot identify the obstruction, the autonomous off-road vehicle can apply a second machine-learned model configured to determine whether or not the obstruction can be ignored, for instance based on dimensions of the obstruction. If the obstruction can be ignored, the autonomous off-road vehicle can continue navigating the route. If the obstruction cannot be ignored, the autonomous off-road vehicle can modify the route, can stop, can flag the obstruction to a remote human operator, can modify an interface of a human operator to display a notification or a video feed from the vehicle, and the like.
