Abstract:

A method for loading digital geographical map tiles by an autonomous or semi-autonomous vehicle from an external server unit. A present speed of the vehicle and a link quality of a data link to an external server unit presently available for the vehicle are ascertained. A territory size to be loaded by the vehicle for a planned driving route is calculated as a function of the speed of the vehicle and the link quality of the vehicle to the at least one external server unit, and a list of map tiles to be loaded is created based on the territory size to be loaded, excluding map tiles already stored in a control unit of the vehicle. A prioritized order of the listed map tiles to be loaded is ascertained, and the map tiles are loaded in the prioritized order.
