Abstract (en)
[origin: EP0412286A2] In a route-selective reproduction method for digitally coded traffic messages transmitted from a transmitter to a vehicle receiver, the only traffic messages which are to be sent to the driver are those which are relevant to his route. The route can be identified by means of transit time measurements of the receivable transmitters. The hyperbolic position-finding known for this purpose requires high computing expenditure on the receiver side. It is proposed according to the invention to store a coordinate grid in the receiver with transit time values of the synchronised transmitters which can be received in a given area and, by comparison of the measured transit time values with stored transit time values, to select the coordonates of the nearest transit time values in the coordinate grid as the vehicle location.
