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.
