Abstract

In a method for the provision and transmission of data, in particular with a link to a vehicle, signals are detected as data that are sent as parts of defined message blocks from a transmitter to a receiver. Data SUB-channels (I, II), via which the data are sent, are defined in the message blocks. The message blocks and data SUB-channels (I, II) are assigned to a CAN bus system. The message blocks accommodate two data SUB-channels (I, II), in particular each with a maximum of 2 bytes.

Claims

1. A method of providing and transmitting data in a data bus system, the method comprising the steps of:

acquiring signals as data;

sending the data as parts of defined message blocks from a transmitter to a receiver, wherein the message blocks contain a definition of one or more data SUB-channels (I, II) via which the data are transmitted.

2. The method as claimed in claim 1, wherein the message blocks and data SUB-channels (I, II) are assigned to a CAN bus system.

3. The method as claimed in claim 1, wherein at least one of the message blocks accommodates two data SUB-channels (I, II).

4. The method as claimed in claim 1, wherein at least one of the at least one data SUB-channel is assigned to a SUB-identifier and contains a signal comprising a maximum of 2 bytes.

15. The method as claimed in claim 3, wherein each of the two data SUB-channels has a maximum of 2 bytes.

16. The method as claimed in claim 4, wherein the SUB-identifier comprises 2 bytes.

5. A system providing and transmitting data in a data bus system in a vehicle, the system comprising

a data bus system, configured for transmitting the data with one or more data SUB-channels (I, II) within a data block

an electronic control unit (EBS-ECU) for configured for providing the data, and

an interface configured for transmitting the data to receivers remote from the vehicle.

6. The system as claimed in claim 5, wherein the interface is a telematics unit (telematics ECU).

7. The system as claimed in claim 6, wherein the telematics unit communicates with a web server, in particular via a mobile radio link (UMTS).

8. The system as claimed in claim 5, wherein the provision and transmission of defined data is performed in response to a request received via the interface.

9. The system as claimed in claim 5, characterized in that wherein the electronic control (EBS-ECU) unit is configured for generating the data from basic data and for transmitting the generated data.

10. The system as claimed in claim 9, wherein functions or links for generating data are transmitted via the interface to the electronic control unit (EBS-ECU), and wherein the electronic control unit then generates correspondingly generated data.

11. The system as claimed in claim 5, wherein at least one sensor is connected to the electronic control unit, the data of which are not used for a main function of the electronic control unit, and in that these data are transmitted from the electronic control unit via at least one of the data SUB-channels (I, II) to the interface.

12. A control unit configured for receiving functions or links via the internet for generating data, for correspondingly generating the data as message blocks, and for transmitting the message blocks from the electronic control unit to an interface, each of the message blocks including at least one data SUB-channel assigned to a SUB-identifier.

13. The control unit as claimed in claim 12, wherein each of the message blocks has two data SUB-channels, each SUB-channel having a maximum of 2 bytes.

14. The method as claimed in claim 12, wherein the SUB-identifier comprises 2 bytes.
