ABSTRACT:
For the determination of the position of a vehicle, navigation parameters are measured, with which periodically dead reckoning coordinates are calculated, which are compared to topographical and traffic technical information stored in a global data base. A local navigation data base is being kept and updated, containing relevant sub-information from the global data base. Using the dead reckoning coordinates test steps are performed on route segments from the local navigation data base, on the basis of which route segments forming possibly driven routes, are stored in a data structure and pseudo-segments are derived from consecutively calculated dead reckoning coordinates which form a pseudo-route and are stored in a further data structure. By comparing the route segments in the data structure and the pseudo-segments in the further data structure a well-founded correction vector for the dead reckoning coordinates is periodically determined.
