In a method of and an apparatus for determining the position of a land vehicle by detecting and evaluating driving data and subsequent correction of the position calculated from the driving data by matching with data of a stored, digitized road network, the determination of the position is carried out in a very reliable manner. By dividing the digital road network into meshes defined according to surface area by covering it with a grid. The meshes in which the instantaneous position of the vehicle is located, are selected one after the other proceeding from a starting position, and the position calculated from the driving data is corrected at predetermined intervals to the possible and most probable position through the road network in the respective selected mesh and its proximate surrounding area.

A method of determining a position of a land vehicle, comprising the steps of dividing a digital road network in a plurality of meshes in a grid-like manner with each mesh containing a predetermined number of street sections that should not be exceeded; determining and evaluating driving data and calculating a position of the vehicle in accordance with the driving data; and correcting the calculated position of the vehicle by comparing the calculated position with possible positions of the digital road network wherein only street sections contained at least in a mesh in which the calculated position is located, are considered.
