摘要： In a process and device for determining the position of a land craft by acquiring and evaluating driving data followed by correcting the position calculated on the basis of the driving data by comparing them with the data of a recorded, digitalised road netword, it is important to be able to determine the position in a reliable way. In the case of an extensive road network, such as a whole state or the whole territory of the Federal Republic of Germany, this can lead to extremely long calculations that stand in the way of a meaningful application of the process. To solve this problem, a grid is superimposed on the road network to subdivide it in meshes of limited surface. Beginning from a starting position, successive meshes are selected, in which the vehicle is situated at a given moment, and the position calculated on the basis of the driving data is corrected in predetermined intervals to give the possible and most probable position of the landcraft given through the road network in the selected mesh and its neighborhood.
