Abstract

A method for storing diagnostic data relating to a vehicle includes the steps of: reading one or more messages, the read messages including diagnostic data relating to the vehicle; transmitting the read messages to a buffer memory; transmitting the read messages to an aggregation component; aggregating the read messages by use of the aggregation component to form an aggregated message; transmitting the aggregated message to the buffer memory; checking whether a predefined fault event occurred during aggregation of the messages by the aggregation component; if a predefined fault event occurred: transmitting the predefined fault event to an extraction component, the predefined fault event including at least one predefined rule; executing the at least one predefined rule by the extraction component in order to extract the messages corresponding to the at least one predefined rule from the buffer memory; and storing the extracted messages and the fault event in a data memory, with the result that the extracted messages can be identified using the fault event.

Claims

1. A method for storing diagnostic data relating to a vehicle, the method comprising the acts of :

reading one or more messages, the read messages comprising diagnostic data relating to the vehicle;

transmitting the read messages to a buffer memory;

transmitting the read messages to an aggregation component;

aggregating the read messages by the aggregation component to form an aggregated message;

transmitting the aggregated message to the buffer memory;

checking whether a predefined fault event occurred during aggregation of the messages by the aggregation component;

if a predefined fault event occurred;

transmitting the predefined fault event to an extraction component,

the predefined fault event comprising at least one predefined rule;

executing the at least one predefined rule of the extraction component in order to extract the messages corresponding to the at least one predefined rule from the buffer memory; and

storing the extracted messages and the fault event in a data memory, with the result that the extracted messages can be identified using the fault event.

2. The method according to claim 1, wherein the extracted messages comprise read messages and aggregated messages.

3. The method according to claim 1, wherein the buffer memory is a ring memory.

4. The method according to claim 1, the method further comprising the act of:

transmitting the extracted messages to a de-duplication component, the de-duplication component removing messages which have been repeatedly extracted before storage in the data memory.

5. The method according to claim 1, wherein:

the extraction component allocates a unique designator to each extracted message; and

/or

the extracted messages and the unique designators of the extracted messages are stored in the data memory.

6. The method according to claim 5, wherein the de-duplication component removes repeatedly extracted messages by use of the unique designator of an extracted message.

7. The method according to claim 6, wherein the extraction component allocates the unique designators of the extracted messages to each fault event.

8. The method according to claim 5, wherein the extraction component allocates the unique designators of the extracted messages to each fault event.

9. The method according to claim 8, wherein the extraction component transmits the fault events, with the allocated unique designators of the extracted messages, to the data memory for storage.

10. The method according to claim 7, wherein the extraction component transmits the fault events, with the allocated unique designators of the extracted messages, to the data memory for storage.

11. A system for storing diagnostic data relating to a vehicle, the system comprising:

a processor and associated memory operatively configured to execute instructions to;

read one or more messages, the read messages comprising diagnostic data relating to the vehicle;

transmit the read messages to a buffer memory;

transmit the read messages to an aggregation component;

aggregate the read messages by the aggregation component to form an aggregated message;

transmit the aggregated message to the buffer memory;

check whether a predefined fault event occurred during aggregation of the messages by the aggregation component;

if a predefined fault event occurred;

transmit the predefined fault event to an extraction component,

the predefined fault event comprising at least one predefined rule;

execute the at least one predefined rule of the extraction component in order to extract the messages corresponding to the at least one predefined rule from the buffer memory; and

store the extracted messages and the fault event in a data memory, with the result that the extracted messages can be identified using the fault event.

12. The system according to claim 11, wherein the extracted messages comprise read messages and aggregated messages.

13. The system according to claim 11, wherein the buffer memory is a ring memory.

14. The system according to claim 11, wherein the extracted messages are transmitted to a de-duplication component, the de-duplication component removing messages which have been repeatedly extracted before storage in the data memory.

15. The system according to claim 11, wherein:

the extraction component allocates a unique designator to each extracted message; and

/or

the extracted messages and the unique designators of the extracted messages are stored in the data memory.

16. The system according to claim 15, wherein the de-duplication component removes repeatedly extracted messages by use of the unique designator of an extracted message.

17. The system according to claim 16, wherein the extraction component allocates the unique designators of the extracted messages to each fault event.

18. The system according to claim 17, wherein the extraction component transmits the fault events, with the allocated unique designators of the extracted messages, to the data memory for storage.

19. A computer product for storing diagnostic data relating to a vehicle, comprising a non-transitory-computer-readable medium having stored thereon program instructions which, when executed on a processor, cause the processor to:

read one or more messages, the read messages comprising diagnostic data relating to the vehicle;

transmit the read messages to a buffer memory;

transmit the read messages to an aggregation component;

aggregate the read messages by the aggregation component to form an aggregated message;

transmit the aggregated message to the buffer memory;

check whether a predefined fault event occurred during aggregation of the messages by the aggregation component;

if a predefined fault event occurred;

transmit the predefined fault event to an extraction component,

the predefined fault event comprising at least one predefined rule;

execute the at least one predefined rule of the extraction component in order to extract the messages corresponding to the at least one predefined rule from the buffer memory; and

store the extracted messages and the fault event in a data memory, with the result that the extracted messages can be identified using the fault event.
