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 and description information, a data packet separately containing locating information and description information, and the data packet containing assignment information for assigning at least a part of the locating information to at least a part of the description information.

Method, data format, encoding device, decoding device and system

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.

Method for outputting data in a vehicle and a driver-information device

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.

Method and wireless transceiver for requesting and processing information

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.

Method for encoding and decoding objects with reference to a road network

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 labeland the length in label

Method for transmitting traffic information about a traffic obstruction

A device for coding and decoding locations in a transportation network, providing that information concerning these locations are transmitted from one transmitter to one receiver. In the device, the code is composed of a declaration portion and a coordinate portion corresponding to each coded location. The coordinate portion includes a plurality of coordinate pairs, one coordinate pair representing the coordinates of the coded location stored on the transmitter side and at least one other coordinate pair representing an auxiliary point. The declaration portion includes at least the number of coordinate pairs contained in the coordinate portion, the position of the coordinate pair of the coded location in the coordinate portion, and an indication of the type of coded location. For decoding purposes, locations falling within the tolerance range of the received coordinate pairs are determined in a location database that contains the coordinates, the position at any time on the traffic route and additional location information. Of the specified locations, the ones situated on a common traffic route are selected; and of these selected locations, the one that falls within the tolerance range of the specified coordinate pair can be defined as the decoded location.

Device for coding and decoding locations

A method for operating a navigational system having a digital map base which is a reproduction of real geographical regions and contains data on geographical elements, as well as a device which retrieves and processes data, such as an operating device having a display unit. In this context, a data directory of the data present in the digital map base is transmitted to the device which retrieves and processes data, and the device which retrieves and processes data selects data, to be requisitioned from the digital map base using this data directory.

Method for operating a navigational system

In a method for encoding objects in a traffic route network, to which information from one transmitter at a time to a receiver is transmitted, and for the encoding and decoding of which different databases, in particular digital maps of the traffic route network, can be used in the transmitter and the receiver, the objects are each provided with at least one coordinate chain, which is located at least in part on traffic routes that are also included in the database of the receiver, and which includes characteristic properties of parts of the traffic route network.

Method for coding and decoding objects in a road traffic network

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.

Method for operating a navigation system

A method for navigating from a starting point, especially from an instantaneous location, to a destination, a routing algorithm of a navigational system for a means of locomotion, particularly a motor vehicle, ship, or airplane, calculating a route from the instantaneous location to the destination via nodal points stored in a digital map. In the case in which at least one of the nodal points of the route to be calculated is not contained in an internal digital map stored internally in the navigational system, the part of the route which exclusively includes nodal points of the internal digital map is calculated by an internal routing algorithm on the basis of the internal digital map as an internally calculated route portion, and the part of the route which does not include nodal points stored in the internal digital map is calculated by an external routing algorithm as an externally calculated route portion on the basis of a digital map stored externally with respect to the navigational system, transitional nodal points from the externally calculated route to the internally calculated route and/or vice versa being determined.

Navigation method and navigation system for means of locomotion

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.
