    摘要: In the case of a position determination method, during traversal of a curve (K) the centroid (Cd) of the latter is determined from measured values of a direction sensor. The centroid (Cm) of the curve (K) of a digitized road (511) is determined from the alignment of road segments (S) of the digitized road which correspond to positions (Pd) determined by dead reckoning. The positions determined by dead reckoning are corrected on the basis of the difference between the determined curve centroids (Cd; Cm).

    摘要: The described navigation system makes use of the attribute pertaining to the existence of “preferred directions,” in particular, inside multi-story car parks. These preferred directions are not limited to a plane or to an orientation. Preferred directions are, in particular, longer entry and exit paths. The method detects a departure from the digitized area and then determines a preferred direction that is defined as a principle axis or a principle axis direction. When traveling within the non-digitized area, e.g. of a multi-story car park, the system monitors whether the vehicle moves within a predetermined limit of the previously defined principle axis direction. If this is the case, it is determined whether a deviation exists and this deviation is optionally corrected to conform with the principle axis direction. This enables compensation of errors that are caused, in particular, by the direction detection.
