1. An apparatus for aligning a measured position for an object with information on a digital map, said apparatus comprising:
- a computation unit that is configured to make a first selection of cartography elements from the map on a basis of the measured position and on a position of a predefined error;
wherein the computation unit is further configured to provide the selected cartography elements for a first and a second secondary computation unit.

Abstract
An apparatus for map matching between a measured position for an object and information on a digital map is specified. This involves a computation unit being used to perform a first selection of cartography elements on the map on the basis of the measured position and on the basis of a predefined error. In addition, the computation unit is designed to provide the selected cartography elements for a first and a second secondary computation unit. In addition, values from the secondary computation units are converted in the same unit of measurement.

12. A process for aligning a measured position for an object with information on a digital map, said process comprising the steps of:
-
providing a computation unit (S1); selecting cartography elements on the map on a basis of the measured position and on a basis of a predefined error by the computation unit (S2); providing the selected cartography elements for a first and a second secondary computation unit by the computation unit (S3).
