Patent number: 11940291Abstract: A method for updating a map of the surrounding area wherein the map is used when controlling a transportation vehicle. The transportation vehicle attempts, when travelling along a carriageway, to detect a landmark recorded in the map of the surrounding area using sensors. In response to the transportation vehicle being unable to detect the landmark using its sensors, the transportation vehicle prepares a proposal for deletion which is sent to an external central computer. The proposal for deletion is examined in the external central computer and deletes the landmark from the map of the surrounding area in response to the proposal for deletion being verified. In the method, information regarding a visibility range for the landmark is entered in the map of the surrounding area specifying at what range the landmark is visible from a road permitting a more effective detection of landmarks.Type: GrantFiled: July 25, 2019Date of Patent: March 26, 2024Assignee: VOLKSWAGEN AKTIENGESELLSCHAFTInventors: Daniel Wilbers, Christian Merfels, Bernd Rech, Thilo Schaper, Niklas Koch, Stefan Jürgens, David Perdomo Lopez, Constanze Hungar
