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 users that are members of a function-specific group of diagnostic-relevant users;

preparing, by a first user that is a first member of the function-specific group, an error entry; and

upon receiving message of the error, storing, by a second user that is a second member of the function-specific group and by a third user that is a third member of the function-specific group, a diagnostic pointer referring to the first user that is the first member,

wherein the users are one of sensors for the function and control units for controlling the function, and

wherein the diagnostic pointer uses less memory space than the error entry.

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

outputting an error message by the first to the second and third users; and

preparing the diagnostic pointer at the second and third users upon receipt of the error message of the first member.

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

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

4. The method according to claim 3, 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 participated or participates in the same or a similar function in an earlier configuration of the motor vehicle or in another motor vehicle type.

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

preparing either an error entry or a diagnostic pointer referring to a member having error entry by all users that are members of the function-specific group.

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

assigning a user, which does not currently participate in the function of the function-specific group in the current configuration of the motor vehicle, as a member of the 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 participated or participates 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 1, further comprising the act of:

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

9. The method according to claim 8, 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 participated or participates in the same or a similar function in an earlier configuration of the motor vehicle or in another motor vehicle type.

10. 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 users that are members of a function-specific group of diagnostic-relevant users;

preparing, by a first user that is a first member of the function-specific group, an error entry;

storing, by a second user that is a second member of the function-specific group a diagnostic pointer referring to the first user that is the first member;

preparing, by a third user that is a third member of the function-specific group, a diagnostic pointer referring to the second user that is the second member of the function-specific group;

wherein the users are one of sensors for the function and control units for controlling the function, and

wherein the diagnostic pointer stored by the second user and the diagnostic pointer prepared by the third user are for the error entry prepared by the first user.

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

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

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

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

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

13. The method according to claim 12, 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 participated or participates in the same or a similar function in an earlier configuration of the motor vehicle or in another motor vehicle type.

14. The method according to claim 10, further comprising the act of:

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

15. The method according to claim 14, 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 participated or participates in the same or a similar function in an earlier configuration of the motor vehicle or in another motor vehicle type.

16. The method of claim 10, wherein the diagnostic pointers each use less memory space than the error entry.

17. The method of claim 10, wherein all users that are members of the function-specific group except for the first user store the diagnostic pointer for the error entry prepared by the first user.

18. The method of claim 17, wherein the all users that are members of the function-specific group are configured in a hierarchical arrangement and the diagnostic pointers stored by the all users that are members of the function-specific group except for the first user refer to a user that is arranged at a next highest level in the hierarchical arrangement.
