Abstract: Proposed is a method for transmitting data in a vehicle, and a driver-information device, where an output unit is connected to processing devices by a data bus. This allows an output for all of the processing devices connected to the data bus to occur centrally in the output unit, whereby, on one hand, only one output unit is necessary for a plurality of processing devices, and on the other hand, processing devices of different manufacturers can be connected to one output unit, when a common data-bus protocol is present.

Abstract: A method and a wireless transceiver are used for requesting and processing information. A first information query is transmitted by the wireless transceiver and information is returned by a service provider via a wireless network to the requesting wireless transceiver. The information query is provided with a predefined first validity time value and the returned information, in particular in the form of short messages, is provided with a predefined second validity time value by the service provider.

Abstract: In methods for encoding and decoding objects with reference to a traffic route network, wherein the encoded information can also be decoded with the aid of databases that differ from a database used in the encoding, the objects are provided with relationships to at least one relational object which is present in databases that are used for the decoding, and the relationships do not primarily result from the traffic route network. A position indication can also be provided with a position type designator, which for instance indicates whether the transmitted position is an exact or navigable position or is the location of a search space.

Abstract: The method of transmitting traffic information about a traffic obstruction on a traffic way with digital coded messages includes coding a coded location contained in a location data bank, which amounts to an approximate position of the traffic obstruction on the traffic way, and a section part of the traffic way between the coded location and an actual position of the traffic obstruction on the traffic way in a traffic message and then transmitting the traffic message. In addition the length of the traffic obstruction can be included in the traffic message. In a preferred embodiment the traffic message is a TMC traffic message coded with ALERT-C protocol. In which the section part is coded in label 12 and the length in label 2.

Abstract: Proposed is a method, a data format, an encoding device, a decoding device and a system for encoding, for decoding and/or for transmitting location information, the location information including both locating information (450) and description information (470), a data packet (400) separately containing locating information (450) and description information (470); and the data packet (400) containing assignment information (460) for assigning at least a part of the locating information (450) to at least a part of the description information (470).

Abstract: The invention relates to a method for operating a navigation system comprising a digital map base, which is a representation of actual geographical areas and which contains data of geographical elements. The navigation-system also comprises a unit, which retrieves and processes the data, such as an operating unit provided with a display device. The data in the digital map base is combined in the form of geographically defined page frames. When requesting a page frame from the digital map base, data of geographical elements which extend beyond the edge of the page frame is transferred in such a manner that data pertaining to these geographical elements located outside of the requested page frame is also compiled and transferred.

Abstract: A method, operating unit, navigation system and interface for displaying a predetermined section of a digital map database, which represents a real geographic area, on a display device are described. The digital map database contains data representing various geographic elements. An attribute, which defines a display priority, is assigned to each geographic element. An evaluation is then performed to determine whether or not particular geographic elements in the predetermined section to be displayed should or should not be visible on the display device. A particular geographic element is made visible on the display device when it is located in the predetermined section and when its display-priority-determining attribute satisfies certain selection criteria or selection rules. This method prevents display of too many geographic elements, which would otherwise make the display congested thus producing an unclear display.
