Steering Method for an Agricultural Machine
20220350344 · 2022-11-03 ·

In a steering method for an agricultural machine, the agricultural machine is steered by track steering action independent of GNSS position data along an initial travel track in a working region until a headland adjoining the working region is reached at an exit point of the initial travel track. The agricultural machine is automatically steered by turn steering action, steering it based on an actual position determined based exclusively on GNSS position data, through the headland until an entry point of a target travel track in the working region is reached. The agricultural machine is steered by track steering action along the target travel track. The agricultural machine automatically detects a transition from a travel track of the working region into the headland and/or a transition from the headland into a travel track of the working region and switches accordingly between turn steering action and track steering action.

METHOD AND APPARATUS FOR FULL COVERAGE PATH PLANNING OVER THREE-DIMENSIONAL TERRAIN

A method for path planning for a machine to traverse an area includes calculating a spline trajectory based on a plurality of control points of a first path. A subset of the plurality of control points having an equal step is selected. A direction of the normal to the spline trajectory for each of the selected points is determined. Control points within the subset that are a solution to a second order cone programming class optimization problem along each normal to the spline trajectory are searched for and the spline trajectory is extended to a border of the area to create a second path adjacent to the first path based on the control points. The optimization problem can minimize the weighted sum of the average curvature at junction points of elementary sections of the spline trajectory and/or the average width overlap of adjacent paths.

Automatic steering of an agricultural machine on an agricultural surface

A method for automatically steering an agricultural machine on an agricultural area that is to be worked. The method includes optically detecting a first region of the area that is to be worked lying in a direction of travel of the agricultural machine in a first recording via a first optical sensor in a first position with a first viewing direction. The method further includes optically detecting a second region of the area that is to be worked lying in the direction of travel of the agricultural machine in a second recording via a second optical sensor in a second position with a second viewing direction. The method additionally includes detecting a tramline in the first recording and detecting a tramline in the second recording, determining a first trajectory and a second trajectory, and determining a steering signal based on the first trajectory and/or the second trajectory.
