Abstract
A method for creating an obstacle map of an area surrounding a motor vehicle on a road includes preparing a rasterized obstacle map, scanning an area surrounding the motor vehicle, dividing the surrounding into cells, recording those of the cells that are occupied by an obstacle, and identifying grid points of the obstacle map that correspond to occupied cells in the surrounding area. The dimensions of the cells are determined as a function of the position thereof relative to the course of the road.

10. A method for creating an obstacle map of an area surrounding a motor vehicle on a road, the method comprising:
-
preparing, by processing circuitry, a rasterized obstacle map; obtaining, by the processing circuitry, a scan of an area surrounding the motor vehicle; dividing, by the processing circuitry, the scanned surrounding area into cells, respective dimensions of each of which are determined as a function of respective positions of the cells relative to a course of the road; recording, by the processing circuitry, which of the cells are occupied by an obstacle; and identifying, by the processing circuitry, grid points of the obstacle map that correspond to the recorded occupied cells. - View Dependent Claims (11, 12, 13, 14, 15)

16. A method for controlling a motor vehicle on a road, the method comprising:
-
creating, by processing circuitry, an obstacle map of an area surrounding the motor vehicle by; preparing a rasterized obstacle map; obtaining a scan of an area surrounding the motor vehicle; dividing the scanned surrounding area into cells, respective dimensions of each of which are determined as a function of respective positions of the cells relative to a course of the road; recording which of the cells are occupied by an obstacle; and identifying grid points of the obstacle map that correspond to the recorded occupied cells; and generating, by the processing circuitry, control signals for the motor vehicle based on the obstacle map to avoid a collision between the motor vehicle and an obstacle.
