Definitions

• the invention relates to a radio signal receiver for motor vehicles with the features that are specified in the preamble of claim 1.
• the traffic information is known in the technical field under the name TMC (traffic message channel).
• TMC traffic message channel.
• problems of such a radio receiver exist with regard to adapting or changing the table for the underlying standards and the data used for the encoding and decoding of the digital signals. Among them are i.w. Understand location codes and standard texts.
• a radio receiver as a radio signal receiver of the type mentioned is known from DE-OS 35 36 820, which itself contains the location codes and standard texts in a read-only memory and which deciphers the transmitted codes and forms speech information therefrom. An adjustment is e.g. to a changed standard not possible.
• EP 0 580 617 B1 describes a radio receiver in which an attempt is made to tackle the problem in the following way;
• a chip card can be inserted into the radio receiver, which contains the location codes and additional data for converting the digital signals in a data memory.
• By exchanging the chip card it is possible to adapt to changed standards as well as changed road conditions and location codes. If location names change, this can be taken into account by using a new chip card.
• such a radio receiver is expensive because it must have a chip card reader.
• the handling of the chip card is not easy, since it is basically removable and can also be lost.
• the invention has for its object to provide a radio signal receiver of the type mentioned, in which a change or adaptation of the radio receiver is not necessary even with changed standards, location codes and the like. And which also offers a possibility of adjustments, changes and updates to perform easily.
• the traffic information is now reproduced using the navigation system. Since this contains the route data memory, the table required for converting the digital signals can also be stored in it. Adjustments and changes can easily be made in connection with corresponding modifications of the navigation system by using a new route data memory with a correspondingly changed table for the TMC information. On the other hand, the necessary adaptation for the RDS / TMC information can be done at the same time when changing the place names. The connection of foreign language texts for the reproduction of the traffic information can also be realized by using a correspondingly designed table in the navigation system.
• the route data memory contains not only the location information but also the other data which are required for outputting the traffic information, such as standard texts, directional information and the like, the entire reproduction of the traffic information, with the exception of the decoding of the RDS signal, has been shifted from the radio receiver to the navigation system. This information is output using the navigation system.
• the output can take the form of acoustic information, e.g. with the help of the speech system of the navigation system or optically e.g. in the map section shown on the screen.
• the TMC radio receiver / navigation system connection can automatically only display those messages from the entire range of messages that are on the selected route.
• the navigation system can define at least one restricted destination corridor (calculated from the position of the road traveled and the previous direction of travel) in which the driver is informed of traffic disruptions. In both cases, there is no need for a complex input procedure for selective message selection.
• TMC messages on the selected or displayed map section and / or the route can be made, for example, by a selection TMC "in the context of a menu display for a vehicle information system containing the navigation system. If this selection is made, incoming TMC messages, possibly to a limited extent temporarily stored in the radio receiver, are displayed. Without this selection, TMC messages are displayed. Messages not considered.
