Error and integrity evaluation during a position determination, includes: recording position values (P, P, P) and calculating clock errors of a receiver via time-discrete runtime measurements by a satellite navigation system; recording a first pseudo-distance at a later time via time-discrete runtime measurement by the satellite navigation system; extrapolating a position value (P') of the receiver at the later time and extrapolating a clock error of the receiver at the later time; establishing a distance (r′) between the extrapolated position value (P′) of the receiver and the position of a satellite (S) of the satellite navigation system at the later time, wherein a quality measure for the usability of the position determination with the satellite is obtained by forming a second pseudo-distance based on the sum of the established distance (r′) and the extrapolated clock error at the later time and comparing the second pseudo-distance with the first pseudo-distance.

Error and integrity evaluation via motion prediction

The disclosure relates to a method and a corresponding execution device. The method includes determining a position of a vehicle by a satellite navigation system, establishing a guaranteed position range, where the guaranteed position range describes the geographical region around the actual position of the vehicle, in which the determined position has to be located according to a specified minimum integrity, matching the determined position with an electronically stored road map and corresponding allocation of the position of the vehicle to a road on the road map, where the road map includes information regarding open spaces without a drivable infrastructure as well as an allocation of roads according to road classes, and validating the road class of the allocated road according to the road map on the basis of the guaranteed position range as well as the information contained in the road map regarding open spaces without a drivable infrastructure.

Method for detecting a road class

The invention relates to a method for error evaluation in position determination, comprising time-synchronous recording of first and second position values, wherein the second position values are recorded by a different measuring method than the first position values; forming a first and a second trajectory (A, B) from the first and the second position values respectively; forming differential vectors (D) between first and second position values recorded at the same time; parallel-shifting the second trajectory (B) along a displacement vector (s) such that the amounts of the differential vectors (D) are minimized on average; evaluating the faultiness of the position determination on the basis of one or more amounts of the differential vectors (D) created as a consequence of the parallel shift.
