Abstract
A method updates a digital map stored in a vehicle. The updated map is consistent and at the same time the amount of data transferred is small. The map has a plurality of map objects, wherein an object identifier and a version number are associated with each map object. The method determines a first map object to be updated, transfers a request data set for updating the first map object from the vehicle to a central computer, wherein the request data set includes the object identifier and the version number of the first map object, determines a change operation of the first map object with respect to the version of the first map object that is indicated by the sent version number, determines further map objects changed in the change operation, assembles an update data set, and transfers the update data set from the central computer to the vehicle.
