Abstract

A method for securing a geographic position of a vehicle includes scanning multiple information sources, which each provide items of information which indicate the position of the vehicle; determining individual positions on the basis of each of items of information of one of the information sources and items of surroundings information in the region of a position hypothesis; validating items of information, the associated individual position of which deviates by not more than a predetermined amount from the position hypothesis; determining the position of the vehicle on the basis of the validated items of information, wherein a change of a quality of the items of surroundings information is determined; and, on the basis of the change, determining a probability at which the determined position deviates by more than the predetermined amount from an actual position.
