20230301235 · 2023-09-28 ·

A method for calibrating a height control system for an implement of an agricultural work vehicle can include providing an input signal to the height control system to adjust a height of the implement relative to the ground surface; monitoring the height of the implement relative to the ground surface; adjusting at least one gain of the height control system; and determining a maximum stability gain of the height control system based on the at least one gain and the monitored height. The maximum stability gain can correspond with a stability point of the height control system at which the height control system transitions from stable to unstable. The method can include setting gain(s) of the height control system based on the maximum stability gain.

A pose detection sensor, of a mobile agricultural machine, generates, for various points along a route traveled by the mobile machine, signals indicative of a pose of the pose detection sensor. A point cloud is identified, based on the signals generated by the pose detection sensor, the point cloud including a set of points that are estimated to correspond to a surface of the ground over which the mobile machine travels. Elevation values are generated for each point in the point cloud. In some examples, a plane is calculated based on the points in the point cloud, the plane including predictive elevation values of the ground surface ahead of the mobile machine.
