Method for providing obstacle maps for vehicles
First Claim
1. A method for the preparation of an obstacle map, wherein the obstacle map comprises cells, wherein the method comprises:
- assigning each of the cells to segments of an environment of the vehicle;
assigning to each of the cells information as to whether the corresponding segment of the environment is occupied by an obstacle;
preparing an environment map, wherein the environment map comprises the cells;
determining a threshold value specification,wherein the threshold value specification specifies different threshold values for the cells of the environment map,wherein the threshold value specification is determined depending on a trajectory of the vehicle; and
preparing an obstacle map basis of the environment map and the threshold value specification.

Abstract
A method for the preparation of an obstacle map, wherein the obstacle map comprises cells, includes assigning each of the cells to segments of an environment of the vehicle, and assigning to each of the cells information as to whether the corresponding segment of the environment is occupied by an obstacle. The method also includes preparing an environment map that comprises the cells, and determining a threshold value specification, where the threshold value specification specifies different threshold values for the cells of the environment map. The threshold value specification is determined depending on a trajectory of the vehicle. An obstacle map is then determined on the basis of the environment map and the threshold value specification.
