Patent ID: 8781733

Claim:
A vehicle system located in a vehicle for map verification comprising: an update module located in the vehicle by which a map update can be loaded; a version memory located in the vehicle in which the map update can be stored separately from an existing map which is stored in another memory device; at least one vehicle sensor, surroundings sensor and/or traffic telematics receiver located in the vehicle; a map update provider configured to compare the map update received from a third party with an output of the at least one vehicle sensor, surroundings sensor and/or traffic telematics receiver and check the map update for plausibility; wherein, when the map update is determined to be plausible based on the comparison, the vehicle system uses the map update for map matching a position of the vehicle; and wherein the existing map extract is overwritten with the updated map extract from the update module if the updated map extract has a higher degree of coincidence with an output of the at least one vehicle sensor, surroundings sensor and/or traffic telematics receiver.
