These objects can have attributes essential to the invention,

• - describe the properties of the objects and
• - which are related to each other by relations.

In this context, attributes may be, for example, classes of roads; For example, relations can be turn-offs between roads.

Sooner or later, in the context of the present invention, the case may arise that required or desired contents, that is to say data and information, are not stored in the static digital map or in its memory 10 are included. In this case sends (-> reference symbol 45 in 1 ) the update unit 40 according to the method a request (-> reference numerals 45 in 1 ) via a transmitter / receiver unit 50 to an (external) information provider 300 ,

• – drahtlos, vorzugsweise über mindestens ein digitales zellulares Telefonsystem sowie dort verfügbare Datenübertragungsverfahren, etwa
• – auf D[igital]E[uropean]C[ordless]T[elephone]-Basis,

• – auf W[ireless]A[pplication]P[rotocol]-Basis, und/oder
• – drahtgebunden, vorzugsweise über mindestens einen fahrzeuginternen Bus von anderen Komponenten im Kraftfahrzeug.

The transmitting / receiving unit 50 sends (-> reference number 530 in 1 ) and receives (-> reference numerals 305 in 1 ) Messages

• Wirelessly, preferably via at least one digital cellular telephone system as well as data transmission methods available there, for example
• On D [igital] E [uropean] C [ordless] T [elephone] basis,

• - on W [ireless] A [pplication] P [rotocol] basis, and / or
• Wired, preferably via at least one in-vehicle bus of other components in the motor vehicle.

The requirements for the data and information transmission can be done in a manner essential to the invention by a single retransmission of the required data and information. However, according to the method, requirements are also possible which include a repeated transmission 305 . 530 each trigger, if the (information) provider 300 new data and information become available.

In addition to that of the first storage unit 10 coming (-> reference number 16 in 1 ) static data and information are sent to a likewise computer-controlled decoding / referencing unit 60 that of the receiver module of the transceiver unit 50 received supplementary and / or additional dynamic data and information transmitted in 1 by the reference numeral 56 is illustrated.

By the decoding module of this decoding / referencing unit 60 the supplementary and / or additional dynamic data and information are first decrypted and then by means of the referencing module of this decoding / referencing unit 60 related to the contents of the digital map.

Within the scope of this referencing process, known referencing methods can be used, for example based on the use of so-called location codes of the R [adio] D [ata] S [ystem] -T [raffic] M [essage] C [hannel]. However, it is also possible to use other generally applicable methods that are currently being developed, for example, in public projects, such as the European Union project [...] AGORA.

Thus, by the present device 100 according to the method from the first storage unit 10 coming static data and information with the requested and then by the external information provider 300 over the bidirectional connection 305 . 530 dynamically supplied data and information combined.

In this way, by means of the present device 100 According to the method not only a regional and / or thematic selection are made, but also data, information and / or messages of different origin, namely data, information and / or messages from a static source (= first memory unit 10 ) and data, information and / or messages from a dynamic source (= external provider 300 ) are merged simultaneously.

From the decoding / referencing unit 60 Transactions are generated and sent to a transaction control unit 70 pass (-> reference number 67 in 1 ). By comparison with any existing data transactions, this transaction control unit can 70 Decide whether new transactions on the second memory provided for the updated digital map 20 present data and information are to be applied (-> reference numerals 74 in 1 ) to update, supplement and / or modify this data and information.

These transactions are handled by the card update unit 40 carried out. After carrying out these transactions, there are (-> references 42 in 1 ) the update unit 40 the contents of the second storage unit 20 for the output (-> reference number 29 in 1 ) over the interface 90 to the information system 200 (-> reference number 920 in 1 ) free.

• – neben der vorerwähnten Verbindung 29 von der zweiten Speichereinheit 20 zur Schnittstelleneinheit 90 sowie
• – neben der vorerwähnten Verbindung 920 von der Schnittstelleneinheit 90 zum Informationssystem 200 jeweils auch
• – eine Verbindung 92 von der Schnittstelleneinheit 90 zur zweiten Speichereinheit 20 bzw.
• – eine Verbindung 209 vom Informationssystem 200 zur Schnittstelleneinheit 90

vorgesehen ist.As shown in the illustration 1 is removable, is the interface unit 90 designed bidirectional in both sides bidirectional in erfindungswesentlicher way, so that

• - in addition to the aforementioned connection 29 from the second storage unit 20 to the interface unit 90 such as
• - in addition to the aforementioned connection 920 from the interface unit 90 to the information system 200 each one too
• - a connection 92 from the interface unit 90 to the second storage unit 20 respectively.
• - a connection 209 from the information system 200 to the interface unit 90

is provided.

In an inventive development of the present device 100 As in the case of the present method, received messages can contain at least one validity period, by means of which it is possible to describe from what time until when the content of this received message is to be taken into account.

Conveniently, the description of this period of validity may also include at least one time-limited or time-unlimited cyclic repetition. To evaluate this validity is the transaction control unit 70 over a unidirectional connection 87 to a timer 80 connected.

This time or clock unit 80 can be implemented as real-time clock in the system; the time or clock unit 80 However, it can also be realized by evaluating the system time of at least one G [lobal] P [ositioning] S [ystem] receiver integrated in driver information systems or at least one radio clock receiver, for example DCF77 (DCF77 is a time signal and is at a standard frequency of 77 , 5 Kilohertz as time information in coded form emitted, the transmission power is about fifty kilowatts with a radiated power of about thirty kilowatts in a range of about two thousand kilometers in the vicinity of Frankfurt am Main or Mainflingen, the name DCF77 was created by international agreements and is composed of the letter D for Germany, the letter C as the identifier of a long-wave transmitter and the letter F because of the proximity of Mainflingen to Frankfurt am Main, the number 77 stands for the transmission frequency used of 77.5 kilohertz, the call sign DCF77 is three times an hour as Morse sign during the minutes 19, 39 and 59 sent).

In a manner essential to the invention, transactions are only processed by the updating unit 40 executed when its validity period begins or has begun. Upon expiration of the validity period, the decoding / referencing unit 60 Generate transactions that undo the original transactions.

For cyclically recurring changes, additions and / or modifications, the transactions can be executed and reversed several times.

Is the validity of a message unlimited, for example, given a permanent change in the road network, and is the memory 10 for the static digital card as a writable memory, for example as a hard disk or as a semiconductor memory (see above), the changes, additions and / or modifications made as a result of this message can be included in the static digital card.

If no validity period is available, the transaction control unit can 70 possibly take a validity period depending on the content of the message. After expiration of one of the transaction control unit 70 assumed validity period, the change, addition and / or modification can be withdrawn and / or a new request for current data and information can be initiated.

• – Einfügen oder Löschen
• – mindestens eines Objektes oder
• – mindestens einer Relation zwischen mindestens zwei Objekten,
• – Ändern mindestens eines Attributs
• – mindestens eines Objekts oder
• – mindestens einer Relation,
• – Aufteilen mindestens eines Objekts und/oder
• – Vereinigen mindestens zweier Objekten

gegeben sind, nachstehend noch im Detail erläutert werden, wobei zu berücksichtigen ist, daß im Rahmen der vorliegenden Erfindung eine Meldung auch mehrere, voneinander abhängige Transaktionen verursachen kann.Since the transactions in the context of the present invention have an essential function, the (data) transactions, which are mainly due to the processes

• - paste or delete
• - at least one object or
• At least one relation between at least two objects,
• - Change at least one attribute
• - at least one object or
• - at least one relation,
• - Splitting at least one object and / or
• - Combine at least two objects

will be explained in more detail below, it being considered that in the context of the present invention, a message can also cause multiple, interdependent transactions.

For example, the insertion of a node, that is, a zero-dimensional object in the road network on an existing line, that is, on a road section, may divide this existing line into, for example, two new (road) sections. Both new sections then expediently receive all the attributes, that is, properties of the previous road section.

The deletion of a node, that is to say of a zero-dimensional object, can lead to the union of two existing lines, that is to say of two road sections, if these two road sections have identical attributes, that is to say identical properties. However, if three or more lines meet at the deleted node, all other lines are also to be deleted except for a maximum of two lines.

In essence, transactions are cyclic and / or shutdown of the system in a nonvolatile (third) memory 30 saved (-> reference number 37 and 73 in 1 ). This storage unit 30 can be designed as a semiconductor memory, alternatively as a magnetically or optically writable medium, for example as a hard disk.

In the case mentioned above, that the (first) storage unit 10 is designed for the static digital card as a writable memory can, in essential to the invention, the (first) memory unit 10 with optional waiver of the (third) storage unit 30 be used for the non-volatile storage of transactions.

So should the system shut down and should the transactions be handled by the (third) storage unit 30 and / or by means of the (first) storage unit 10 deposited, the transaction control unit reads 70 after switching on the system, the transactions are again from the non-volatile memory 30 respectively. 10 and checks based on the validity period and / or on the time of the timer 80 whether these transactions are still valid.

If this is the case and validity can (still) be affirmative, then these transactions can be re-applied to the contents of the static digital map; otherwise, that is, if validity can not (more) be answered in the affirmative, these transactions will be deleted.

Regarding the detectability of the present device 100 As well as the present procedure, the transmission of data, information and / or notifications should expediently follow at least one existing, standardized and / or at least disclosed procedure in order to ensure sufficient dissemination on the market and with the (external) information providers 300 to achieve.

As stated above, the transmission of the data, information and / or messages is coded in order to use the transmission channels in an economically sensible manner; Consequently, the aforementioned decoding device (decoding module) is within the scope of the decoding / referencing unit 60 available.

Since it can not be assumed that the particular external information provider 300 and databases of the same manufacturer with directly usable references are used in the motor vehicle, the aforementioned referencing device (referencing module) is part of the decoding / referencing unit 60 available; the method is not specifically defined at this point, using known referencing methods (see above).

Finally, it should be noted that changes, additions and / or modifications in databases are made through the transactions described above. In order to be able to undo these transactions, corresponding complementary transactions are to be applied in a manner essential to the invention.
