Dabei kann das Funknetz ein zellulares Mobilfunknetz sein, wobei einzelne Sender Höchstgeschwindigkeitswerte mit Angaben zu den zugeordneten Streckenabschnitten für jeweils die im Bereich einer Zelle oder mehrerer benachbarter Zellen liegenden Streckenabschnitte senden. Bei dieser Aüsführungsform wird das Mobilfunknetz lediglich als eine Vielzahl von lokalen Rundfunksendern genutzt.According to the invention is to update the stored maximum speed values provided that Via a radio network maximum speed values with information on the associated route sections can be received and in Storage can be stored.
