Abstract

In a method for structured storage of error entries of the users of a data bus in a motor vehicle, upon occurrence of an error, a function possibly influenced by the error and the members of an associated function-specific group of diagnostic-relevant users is determined, an error entry is prepared at a first member of the function-specific group, and a diagnostic pointer referring to the first member is stored at a second member of the function-specific group.

Claims

1. A method for structured storage of error entries of the users of a data bus in a motor vehicle, the method comprising the acts of:

determining, upon occurrence of an error, a function possibly influenced by the error and members of an associated function-specific group of diagnostic-relevant users;

preparing an error entry at a first member of the function-specific group; and

storing a diagnostic pointer referring to the first member at a second member of the function-specific group.

2. The method according to claim 1, further comprising the acts of:

outputting an error message by the first member to the second member; and

preparing the diagnostic pointer at the second member upon the error message of the first member.

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

preparing a diagnostic pointer referring to the second member, which may be cascaded with the diagnostic pointer of the second member, at a third member of the function-specific group.

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

outputting an error message by the second member to the third member; and

preparing the diagnostic pointer of the third member based on the error message of the second member.

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

preparing either an error entry or a possibly cascaded diagnostic pointer referring to a member having error entry at all members of a function-specific group.

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

assigning a user, which does not participate in the function founding the function-specific group in the current configuration of the motor vehicle, as a member of a function-specific group.

7. The method according to claim 6, wherein the user which is assigned as a member of a function-specific group and does not participate in the function in the current configuration of the motor vehicle did/does participate in the same or a similar function in an earlier configuration of the motor vehicle or in another motor vehicle type.

8. The method according to claim 2, further comprising the act of:

preparing a diagnostic pointer referring to the second member, which may be cascaded with the diagnostic pointer of the second member, at a third member of the function-specific group.

9. The method according to claim 2, further comprising the acts of:

outputting an error message by the second member to the third member; and

preparing the diagnostic pointer of the third member based on the error message of the second member.

10. The method according to claim 3, further comprising the acts of:

outputting an error message by the second member to the third member; and

preparing the diagnostic pointer of the third member based on the error message of the second member.

11. The method according to claim 2, further comprising the act of:

assigning a user, which does not participate in the function founding the function-specific group in the current configuration of the motor vehicle, as a member of a function-specific group.

12. The method according to claim 3, further comprising the act of:

assigning a user, which does not participate in the function founding the function-specific group in the current configuration of the motor vehicle, as a member of a function-specific group.

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

assigning a user, which does not participate in the function founding the function-specific group in the current configuration of the motor vehicle, as a member of a function-specific group.

14. The method according to claim 5, further comprising the act of:

assigning a user, which does not participate in the function founding the function-specific group in the current configuration of the motor vehicle, as a member of a function-specific group.

15. The method according to claim 2, further comprising the act of:

assigning a user, which does not participate in the function founding the function-specific group in the current configuration of the motor vehicle, as a member of a function-specific group.

16. The method according to claim 3, further comprising the act of:

assigning a user, which does not participate in the function founding the function-specific group in the current configuration of the motor vehicle, as a member of a function-specific group.

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

assigning a user, which does not participate in the function founding the function-specific group in the current configuration of the motor vehicle, as a member of a function-specific group.

18. The method according to claim 5, further comprising the act of:

assigning a user, which does not participate in the function founding the function-specific group in the current configuration of the motor vehicle, as a member of a function-specific group.
