ABSTRACT

The invention relates to a method and device for controlling the movement of a vehicle. The method acquires a cloud of three-dimensional data obtained by reflection of waves emitted by sensors on board the vehicle; transforms the cloud of three-dimensional data into a cloud of two-dimensional points expressed in a polar coordinate system, modifies this two-dimensional point cloud by deleting a current two-dimensional point whenever two two-dimensional points adjacent to the current two-dimensional point are not sufficiently far away from each other to avoid a collision between the vehicle and an object close to this vehicle, and controls the movement of the vehicle as a function of a convex envelope formed by the two-dimensional point cloud modified in this way and defining a free space accessible to the vehicle.
