ABSTRACT:
The present invention relates to a method for automatically establishing an updating a table of distances by means of a vehicle which is equipped with a computer unit and a trip meter, which vehicle is driven along a route extending past a group of predetermined stops which are represented in a list stored in a computer unit. Each time the vehicle stops at a stop, the computer unit receives from the trip meter data which represents a distance that has been covered since the preceding stop. If the list lacks information about said distance, the data is stored in the list associated with the current location, whereas if the list already contains information about said distance, the data is allowed to affect the information by suitable statistical processing. By means of this method, a table of distances is automatically established, and is also updated each time the vehicle stops at a location along the route. During one single driving, a new route can thus be given complete distance information, which in future makes correct stop call-outs etc. possible.
