Process and arrangement for determining the position of at least one point of a track-guided vehicle

A process for determining a position of at least one point of a vehicle moving on a given track, the process comprising the steps of:

• obtaining in a mutually independent manner at least a number n of different types of position measuring data, with n being greater than or equal to three, by detecting objects present along the given track, a travelled path length of the vehicle, and a travelled route course of the vehicle;
• determining a position result for each different type of position measuring data detected using a respective correlation of the detected position measuring data with a corresponding stored desired data quantity;
• and
• determining the position of the vehicle from the position result for each type of detected measuring data by performing an m-out-of-n decision making process, where m=(n-x) and x is defined by the number of positions results not used for the analysis, said process determining a given number m from the number n of independently determined position results situated within an interval having a given resolution width, said interval being evaluated as the position to be determined.
