Abstract

According to the invention, in a transfer of data (1) to at least one mobile unit the data (1) are provided with an identifier (7) that assigns the data (1) to the at least one mobile unit. The data (1) are assembled into a data stream (20) receivable by a multitude of mobile units, which is transmitted by means of at least one transmitting device (8) via at least one transmission path (22). At the mobile unit (23) end the data stream is received by means of at least one receiving device (9) and the data (1) are filtered from the received data stream (20) on the basis of the identifier (7).

Claims

1. A method of transferring operating software of a motor vehicle to at least one mobile unit arranged in the motor vehicle, the method comprising:

labeling of operating data with an identifier that assigns the operating data to the at least one mobile unit;

providing a data stream which comprises a plurality of transmission units labeled with the identifier, wherein the data stream is receivable by a multitude of mobile units, and wherein a portion of the transmission units include portions of the labeled operating data of the motor vehicle;

repeatedly transmitting the transmission units of the data stream by means of at least one transmission device via at least one transmission path;

receiving the data stream by means of at least one receiving device of the at least one mobile unit in the motor vehicle;

filtering of the transmission units from the data stream on the basis of their identifier from the received data stream in the at least one mobile unit in the motor vehicle; and

re-assembling in the motor vehicle of the operating data from the filtered transmission units in the at least one mobile unit;

wherein upon filtering of the transmission units from the data stream, the transmission units which are assigned to the at least one mobile unit on the basis of the identifier are stored to re-assemble the operating data into the operating software while other transmission units from the data stream are discarded;

wherein the data stream with the transmission unit provided with the identifier is transmitted by a multitude of transmitting devices; and

wherein the receiving device of the at least one mobile unit is configured to receive the transmission units transmitted by various transmitting devices.

2. The method according to claim 1, wherein the data to be transferred are encrypted and the received data are decrypted in the at least one mobile unit.

3. The method according to claim 1, wherein the data stream is transmitted via multiple transmission paths;

and wherein the at least one mobile unit comprises multiple receiving devices which are configured to receive the data stream with the transmission units provided with the identifier via one of the transmission paths, respectively.

4. The method according to claim 1, wherein the at least one transmission path comprises a short range wireless connection.

5. The method according to claim 1, wherein the at least one transmission path comprises a long-range wireless connection.

6. The method according to claim 1, wherein the at least one transmission path comprises a wired connection.

7. The method according to claim 1, wherein the identifier assigns the data to multiple mobile units.

8. The method according to claim 1, wherein the data stream comprises data which are to be transferred to at least one further mobile unit and are assigned to the at least one further mobile unit with a further identifier.

9. A device for receiving operating software of a motor vehicle in a mobile unit arranged in the motor vehicle, the method comprising:

a receiver in the motor vehicle for receiving a data stream comprising a plurality of transmission units which are labeled with an identifier which assigns the labeled transmission units to the mobile unit, wherein some of the transmission units include portions of the operating software of the motor vehicle, the transmission units being repeatedly sent out by a multitude of transmitting devices and being receivable by a multitude of mobile units;

a filter for filtering the labeled transmission units from the received data stream on the basis of the identifier;

memory of the receiver for storing the labeled transmission units which are assigned to the at least one mobile unit by the identifier; and

a processor of the receiver for discarding other transmission units of the data stream that do not include the portions of the operating software and re-assembling the stored and labeled transmission units which are filtered from the data stream on the basis of the identifier to compile the operating software;

wherein the receiver is configured to receive the transmission units from various transmitting devices.

10. The device according to claim 9, comprising:

means for decrypting the received data in the mobile unit.

11. The device according to claim 9, comprising:

multiple receiving devices which are configured to receive the data stream with the transmission units via one of the transmission paths, respectively.

12. The device according to claim 9, wherein the at least one transmission path comprises a short range wireless connection, a long range wireless connection, or a wired connection.

13. A system for transferring data to at least one mobile unit in a motor vehicle wherein the data transferred to the at least one mobile unit comprise operating software, comprising:

a plurality of devices for transferring data to the at least one mobile unit, which comprises labeling means for labeling transmission units of a data stream with an identifier which assigns the transmission units to the at least one mobile unit, the transmission units being receivable by a multitude of mobile units, and including portions of labeled operating data, and transmitting means which repeatedly send out the transmission units via at least one data path to the at least one mobile unit;

a device for receiving data in a mobile unit, which comprises a receiver for receiving the data stream and filter means for filtering the labeled transmission units from the data stream on the basis of the identifier;

means for storing the labeled transmission units which are assigned to the at least one mobile unit by the identifier;

means for discarding other transmission units received from the data stream; and

means for re-assembling transmission units which are filtered from the data stream on the basis of the identifier to re-assemble the operating data into the operating software for the motor vehicle; and

wherein the receiver is configured to receive the transmission units from various transmitting devices.

14. The system according to claim 13, comprising:

encryption means for encrypting the data to be transferred.

15. The system according to claim 13, comprising:

a multitude of transmitting devices for transmitting the data stream via multiple transmission paths.

16. The system according to claim 13, wherein the at least one data path comprises a short range wireless connection, a long range wireless connection or a wired connection.

17. A motor vehicle, comprising:

at least one mobile unit with a receiver for receiving a data stream comprising transmission units which are labeled with an identifier which assigns the labeled transmission units to the mobile unit, the transmission units being repeatedly sent out and being receivable by a multitude of mobile units and filter means for filtering the labeled transmission units from the received data stream on the basis of an identifier wherein the transmission units include portions of the labeled operating data of the motor vehicle and are repeatedly transmitted by means of at least one transmission device via at least one transmission path;

means for storing labeled transmission units which are assigned to the at least one mobile unit by the identifier;

means for filtering the stored labeled transmission units from the data stream based on their identifier from the received data stream;

means for discarding other transmission units of the data stream; and

means for re-assembling the transmission units which are filtered from the data stream on the basis of the identifier wherein the operating data are re-assembled into operating software for the motor vehicle; and
