Abstract

A distributed computer-implemented diagnostic system for determining a diagnostic state of a component. The component exhibits measurable characteristics. The system includes a database that stores reference component characteristic data. A computer server is connected to the database, and a computer client is connected to the computer server via a network. The client computer provides data requests to the server computer in order to retrieve the component characteristic data from the database. A portable computer is connected to the computer client in order to have data access to the retrieved component characteristic data and to provide the component characteristic data for performing diagnosis. The diagnostic state of the component is determined based upon the retrieved component characteristic data as provided by the portable computer and upon at least one of the measurable characteristics of the component.

Claims

1. A method for evaluating the diagnostic state of a component comprising:

Identifying, using a personal computer, a component characteristic having a measurable value;

communicating the component characteristic from the personal computer to a computer client;

connecting said computer client with a computer server having a database that includes component information;

retrieving, by said computer client, said component information from said computer server database so as to obtain retrieved component information;

communicating the retrieved component information relevant to the component characteristic from the computer client to the personal computer,

measuring a value of said component characteristic of said component; and

formulating a diagnostic state of a component based upon said retrieved component information and the measured value of the component characteristic.

2. The method according to claim 1, wherein said computer server is a secured internet server and wherein said computer client is communicated with said computer server via a network.

3. The method according to claim 1, wherein said portable computer is communicated with said computer client via wireless communications.

4. The method according to claim 1, wherein said component information is responsive to operational characteristics of said component.

5. The method according to claim 1, wherein said component information is responsive to physical characteristics of said component.

6. The method according to claim 1, wherein said computer server database is a relational database, wherein said component information is stored within said computer server database in a relational manner.

7. The method according to claim 1, wherein said communicating includes accessing said computer server database via said computer client, wherein said computer client is accessed via a portable computer.

8. The method according to claim 1, wherein said retrieving includes communicating an information request to said computer server, wherein said information request includes component identification.

9. The method according to claim 8, wherein said component identification includes a vehicle identification number.

10. The method according to claim 8, wherein said retrieving includes communicating said retrieved component information to a portable computer, wherein said retrieved component information is responsive to said information request.

11. The method according to claim 1, wherein said retrieving includes storing said retrieved component information into a portable computer.

12. The method according to claim 1, wherein said formulating includes examining said component so as to determine a component characteristic.

13. The method according to claim 12, wherein said examining said component includes measuring operational characteristics of said component.

14. The method according to claim 12, wherein said formulating includes comparing said component characteristic with said retrieved component information so as to diagnose a component problem.

15. The method according to claim 1, wherein said formulating includes determining service requirements for said component.
