Abstract (en)
[origin: DE19747230A1] The invention relates to taking account of supplementary traffic information for the functioning of a motor vehicle navigation device which is installed in a vehicle and contains an internal digital street map. The starting point and destination are transferred to a central computer and a route plan is transmitted to the automobile navigation device installed in a vehicle, said route plan having been generated in a central computer taking supplementary traffic information into account. The aim of the invention is to carry out this process with a low data transmission rate and short transmission times. To this end, the internal digital street map of the navigation device is provided with data for a location coding. Also, the transmission of the route planning occurs by using the data of the route segments defined by the location coding, said route segments lying between the starting point and the destination. The transmitted route segments are modified in the internal digital street map of the navigation device (1) such that they, compared to other non-transmitted route segments, are considered following the route search carried out in the navigation device installed in the vehicle.
