1. A method for error evaluation in position determination, comprising:
recording of first and second position values, wherein the second position values are recorded by a different measuring method than the first position values;
temporal synchronizing of the first and second position values and forming a first and a second trajectory (A, B) each from the synchronized first and second position values;
forming differential vectors (D) between the respectively synchronized first and second position values;
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 and/or integrity 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; and
wherein the respective measuring method corresponds to one or a combination of the following:
runtime measurement,
Doppler measurement,
carrier phase measurement,
and/or motion estimation by means of cameras, radar, and/or lidar.
