Abstract

A method for diagnosing a malfunction in an automobile that uses a diagnosis tool and an analysis of data or control instructions provided by a calculation module assembly onboard the vehicle and converting the operation of a set of functional members of the vehicle by dynamically displaying the values of the data or the links to the controls within the display of the diagnosis method. The method includes: developing an enriched display structure of the vehicle operation control; developing a list of control data to be refreshed; recovering the refreshed control data from the respective calculation modules; and developing a final display from the enriched display structure and the refreshed control data; wherein the developing an enriched display structure, the list of data to be refreshed, and the recovering the refreshed data and of developing the final display are carried under control of a supervision module.

Claims

1-11. -11. (canceled)

12. A method of diagnosing a malfunction of an automobile by using a diagnostic tool and by analyzing control data or instructions available from a set of computation modules onboard the vehicle and reflecting operation of a set of functional members of the vehicle, the method comprising:

generating an enriched display structure for controlling operation of the vehicle describing a sequence of control operations to be performed on the vehicle enriched with control data or instructions;

generating a list of control data to be refreshed;

dynamically recovering refreshed control data originating from the respective computation modules; and

generating a final display from the enriched display structure, the refreshed control data, and direct access to the control instructions,

the generating the enriched display structure, the generating the list of data to be refreshed, the dynamically recovering the refreshed data, and the generating the final display being carried out under control of a supervision module.

13. The method as claimed in claim 12, wherein, during the generation of the list of control data to be refreshed, diagnostic requests are generated from a base containing, for the computation modules, a list of data requests.

14. The method as claimed in claim 12, wherein, during the recovery of the control data, one or more responses transmitted by each computation module is/are decoded.

15. The method as claimed in claim 14, wherein a refreshed control data file is updated based on the recovered control data.

16. The method as claimed in claim 15, wherein the final display is generated from the enriched display structure, from the refreshed control data file, and from display parameters extracted from a display database that correspond to a human/machine interface on which the final display is to be viewed.

17. The method as claimed in claim 12, wherein, during the generating the enriched display structure and during the generating the list of control data to be refreshed, a diagnostic file is analyzed that contains a set of diagnostic instruction codes for the diagnostic tool and a set of markers for applying diagnostic instruction codes, the markers are detected and the markers are analyzed so as to produce a discrimination between a first type of markers tending to apply an action on the part of an operator and a second type of markers tending to recover control data or control instructions.

18. The method as claimed in claim 17, wherein, when a marker of the first type is detected, textual data or images are inserted into the enriched display structure.

19. The method as claimed in claim 18, wherein, when a marker of the second type is detected, the marker is discriminated between a marker of a third type tending to control a diagnostic function and a marker of a fourth type tending to acquire computation data values.

20. The method as claimed in claim 19, wherein, in response to the detection of a marker of the third type, a control marker is inserted into the enriched display structure making it possible to activate the control.

21. The method as claimed in claim 20, wherein, in response to the detection of a marker of the fourth type, there is inserted, into a file containing the data to be refreshed, a software component for controlling the reading of control data.

22. A system for diagnosing a malfunction of a vehicle, comprising:

a first stage that generates an enriched display structure for controlling the operation of the vehicle and generating a list of control data to be refreshed;

a second stage that recovers refreshed control data originating from computation modules onboard the vehicle;

a third stage that generates a final display from the enriched display structure and from the refreshed control data; and

one or more supervision stages that control the first, second, and third stages and actions of a user technician.
