Definitions
- the invention is based on a method for outputting textual information by means of a display in a driver information system according to the category of the independent patent claim.
- Driver information systems which output textual information by means of a display are known in the form of receivers for traffic reports transmitted by radio, for example from DE 35 36820 C2.
- DE 35 36 820 C2 and ISO standards 14819-1, -2 and -3 describe, among other things, a method for the coded transmission of traffic reports.
- an existing message is broken down into elements on the transmitter side, the elements are coded in accordance with a catalog of standardized message elements, and these codes are then transmitted.
- the received codes are in turn assigned to message elements stored in a table, and the traffic message composed of the message elements assigned to the codes is thus shown on the display.
- Exchangeable storage media such as CD-ROM and DVD in particular, are often provided for storing the decoding table.
- Today's receivers for traffic reports of the type described often have an advertisement with a capacity of four to five lines, each with at least 16 characters as a rule.
- To one and the same decoding table and thus one and the same data carrier for decoding the radio received the information elements stored there are generally limited to a length of 16 characters. If the display capacity of such a driver information system is to be used optimally, decoding tables adapted to a respective display capacity of the respective device are currently required.
- Car hire from a car rental company can be used. This may reduce the acquisition costs for the data carriers required for the operation of the driver information systems.
- FIG. 1 shows a block diagram of a driver information system 2 according to the invention for executing the method according to the invention with an information data carrier 24 for use in the driver information system. Description of the embodiments
- a basic idea of the invention is to break down all the information to be output on a display of a device, in particular a fault information system for motor vehicles, into at least two basic components, and to provide an abbreviation for each basic component in addition to a full text version, i.e. in a memory of the device, for example a CD -ROM or the like.
- a full text version i.e. in a memory of the device, for example a CD -ROM or the like.
- the decomposition can advantageously also be applied to the individual information elements, to which full-text versions or abbreviated versions of the information element components are then used if necessary
- Output of the information consisting of the information elements are output.
- the figure shows a block diagram of a driver information system 2 according to the invention for executing the method according to the invention.
- the driver information system 2 is a receiver for traffic reports transmitted via radio according to the TMC standard of ISO 14819-1, -2 and -3 within the RDS (Radio Data System) signal without any restriction of generality. These are emitted as part of a radio signal 11 by a transmitter 1 in a manner known per se via an FM radio frequency, which is frequency-modulated, among other things, with the radical data signal.
- the broadcast signal 11 is received by a receiving antenna 20 of the driver information system 2 and demodulated in a demodulator 21. The pending at the output of the demodulator 21, the actual ones of interest here
- Signal containing information is supplied to a decoder 22 for decoding the RDS-TMC signal.
- the signal present at the output of decoder 22, which contains the actual traffic announcement codes, is fed to an output controller 23.
- the output control 23 has the task of adapting textual information to be displayed on a display 25 to the capacity of the display 25 and of performing the display.
- the textual information to be displayed is traffic reports which are obtained from the received RDS-TMC codes. To do this, the
- Output control 23 returns to a decoding table 24 in which information elements or message elements are assigned to the codes.
- the decoding table 24 is implemented in the form of an exchangeable data carrier, here for example in the form of a CD-ROM, which is accessed with a corresponding CD-ROM reader.
- the data carrier 24 contains the textual information to be shown on the display.
- Each information element on the data carrier is divided into at least two, in the case of the present exemplary embodiment, preferably in each case in three components, namely a so-called prefix, main part and suffix, and subsequently also prefix, body and suffix.
- Location codes are encoded, in particular, motorway entrances and exits, triangles and junctions for motorways, rest areas, important intersections of federal highways, etc.
- Each of these location codes is assigned at least one street name and one place name, in particular the place name for issuing the traffic report in text form on a display 25 of the device or in acoustic form via a speech synthesis unit 26 of the device.
- Such a place name is an information element in the sense of the present invention.
- the name of the coded location is broken down as an information element into the three components Prefix 2411, Body 2412 and Suffix 2413, which three components are assigned to the associated location code 241 and are stored on the data carrier 24.
- each of the three components is assigned an abbreviated component "Shorted Prefix” 2414, "Shorted Body” 2415 and “Shorted Suffix” 2416.
- Not all of the three components are necessarily present, nor does one necessarily have to be for each existing component appropriate abbreviation is available.
- a missing component or an abbreviation Shorted Prefix 2414, Shorted Body 2415 or Shorted Suffix 2416 means the corresponding component, then with the content "". All components and their respective abbreviations are listed on the Data carriers are addressed together by the associated location code 241 or event code 242.
- event code 1392 reference number
- Shorted Prefix 2424 "eighth.”
- Shorted Body 2425 "wrong-way driver”
- Shorted Suffix 2426 "".
- Information elements here in particular location and event identifiers, is the adaptation of the information output to the display capacity of the display 25. This can vary in particular in the number of lines of text available for output, furthermore the number of characters per line and / or the character set used for the display , namely distinguish, for example, proportional or non-proportional character set.
- the display control 23 controls, depending on the display capacity, the following message text outputs, for example.
- the textual representation of the information here the traffic reports, which are composed of several pieces of partial information, takes place in sections, whereby in the present case a separate line of the display unit 25 is available for each partial information.
- the individual pieces of partial information to be displayed are the road affected by a traffic disruption, the affected road section with a direction, the location of the traffic-relevant event, which is delimited by the neighboring coded locations, and the traffic-relevant event itself.
- Each of the partial information mentioned comprises at least one information element, for example, the partial information event is formed from a single information element, while the partial information directional information three partial elements, namely a first place name, erJjn-Wedding ", a second place name" Berlin-
- 3rd line Location between AS Achterburg and AS Meisdorf
- Each line of the display 25 is constructed from the XML character string generated by the display controller 23, taking into account the maximum line length that can be represented. If no proportional font is used, the line length is determined from the maximum number of characters, otherwise from the maximum pixel count per
- these values as well as the font used (proportional / non-proportional) are stored in the display controller 23 for each device or alternatively can be checked by the display controller 23.
- the line length can be shortened using the abbreviations of the stored prefix, body and / or suffix.
- the line length is preferably shortened according to the following rules.
- Rules are first processed for a first piece of information before they are then applied to the next piece of information in the line.
- the main part of the information or an information element is considered to be particularly essential for the output. Therefore, if an abbreviation of information components is required, the prefix and suffix are preferably first abbreviated and, if necessary, completely omitted before the main part is output in the abbreviated form.
- the order in which the rules are applied also means that the suffix is considered to be of less importance than the prefix.
- the rules shown represent a particularly preferred procedure. Nevertheless, deviating rules are also possible, as are deviating sequences in the application of the rules. These are also within the scope of the present invention.
- the main part is first output in an abbreviated version, provided that the abbreviated version of the main part comprises at least one character.
- the design of the information components and their abbreviations on the data carrier are adapted to the applied rules and their order of use.
- the one described here Alternative rule sequence can be provided that a comparatively detailed and possibly self-explanatory version is stored for the abbreviated main part, while very short abbreviations are chosen, for example, especially for post, but also prefix.
- TMC traffic reports which, as described, as a rule consist of several pieces of information, namely the road concerned, route section with directions, event location and event, each piece of information again comprising at least one information element.
- this does not limit the invention to the representation of TMC messages and also not to the data structure described. Rather, it can also be provided according to the invention that the information is not composed of information elements, but that the information itself represents the smallest information unit.
- the breakdown according to the invention into the components prefix, main body and suffix is applied directly to the information and the display method is also carried out with these components.
- the invention is not limited to receivers for coded traffic reports, rather it is applicable to any information system with a textual information output.
- Another possible application example are vehicle navigation systems, in which directions of travel can be shown in text form on a display. Further different applications are possible and are within the scope of the present invention.
- the invention can be applied to largely any devices that generate information to be displayed on a display unit and to largely any information to be displayed.
- an acoustic output can also be provided via a speech synthesis device with a connected loudspeaker 26.
- the display capacity can be limited, for example, and the information can thus be output in a more or less shortened form, while the information can be output acoustically in the complete version.
- the display control as part of the guest control 23 also accesses the abbreviated versions of the prefix, main part and suffix, while the Output control for acoustic outputs preferably uses the full versions of prefix, main body and suffix for each piece of information from the data carrier 24.
- the invention was explained above using the example of a receiver for traffic reports transmitted via FM radio. However, this does not imply any restriction of the invention either to the origin or type of the messages or to the transmission method or medium, provided that the messages are transmitted.
- the transmission of traffic reports according to the TMC standard also involves radio transmission by means of other analog or digital Broadcasters in question, such as the AM-RBDS, which
- RDS is similar to or similar to DASS (Digital Audio Broadcasting), DVB (Digital Video Broadcasting) or others. Transmission of traffic reports using the point-to-point method, for example via GSM (Global System for Mobile communication) or UMTS mobile radio, is also possible
- the information does not necessarily have to be output directly by means of a display of the recipient or the device generating the messages. Rather, it is also possible for the information to be output via a separate display unit.
- a hand-held computer such as a PDA or the like, can be connected as a separate display unit, for example via an infrared or Bluetooth interface, to the device generating or making the messages available, and the information provided by the device via the interface displayed on the PDA.
- the device providing the information for example a radio receiver with a TMC message decoder, is aware of the display capacity of the external display device, that is to say of the PDA, for example. This information can be queried by the radio receiver, for example via the Bluetooth interface, from the external display device.
