Abstract

An integrated diagnosis and prognosis system that collects vehicle information over the life of a vehicle and its development. The system provides the collected vehicle information to supplier management, product development management, service/dealership management, customer relations departments and production facilities, which use the information to take certain action for existing vehicles, fleets of vehicles or future vehicles to improve vehicle reliability and quality.

Claims

1. An integrated diagnosis and prognosis system comprising:

a processing sub-system configured to collects on-board and off-board diagnosis and prognosis information about vehicle sub-systems and components from vehicle assembly until vehicle end of life, wherein the collected information relates to one or more vehicles, said processing sub-system providing the collected information;

a supplier management sub-system responsive to the collected information from the processing sub-system, said supplier management sub-system taking certain actions depending on the collected information to improve vehicle reliability;

a product development management sub-system responsive to the collected information from the processing sub-system, said product develop management sub-system taking certain actions depending on the collected information to improve vehicle reliability;

a service/dealership management sub-system responsive to the collected information from the processing sub-system, said service/dealer management sub-system taking certain actions depending on the collected information to improve vehicle reliability;

a customer relations sub-system responsive to the collected information from the processing sub-system, said customer relations sub-system taking certain actions depending on the collected information to improve vehicle reliability; and

a production sub-system responsive to the collected information from the processing sub-system, said production sub-system taking certain actions depending on the collected information to improve vehicle reliability.

2. The system according to claim 1 wherein the supplier management sub-system provides spare part scheduling and inventory management to improve vehicle reliability.

3. The system according to claim 1 wherein the product development management sub-system improves vehicle design, updates vehicle requirements, updates vehicle diagnosis algorithms, updates system validations and provides remote software downloads to improve vehicle reliability.

4. The system according to claim 1 wherein the service/dealership management sub-system updates service procedures and schedules service for the vehicle to improve vehicle reliability.

5. The system according to claim 1 wherein the customer relation sub-system performs prognosis and predictive vehicle maintenance, makes warranty decisions, produces product recalls and provides remote vehicle diagnosis to improve vehicle reliability.

6. The system according to claim 1 wherein the production sub-system performs assembly testing, updates assembly processes and provides production planning to improve vehicle reliability.

7. The system according to claim 1 further comprising a distributed database that stores the collected information to be assessable to the supplier management sub-system, the product development management sub-system, the service/dealership management sub-system, the customer relations sub-system and the production sub-system for future vehicles.

8. An integrated diagnosis and prognosis system for collecting on-board and off-board diagnosis and prognosis information about vehicle systems, sub-systems and components through the entire life-cycle of a vehicle from design and development of the vehicle to maintenance and use of the vehicle, wherein the collected information relates to one or more vehicles and is received from a plurality of sources, said system providing the collected diagnosis and prognosis information to various entities involved in the life-cycle of the vehicle and the life-cycle of future vehicles.

9. The system according to claim 8 wherein one of the entities is a supplier management that provides spare part scheduling and inventory management.

10. The system according to claim 8 wherein one of the entities is product development management that improves vehicle design, updates vehicle requirements, updates vehicle diagnosis algorithms, updates system validations and provides remote software downloads.

11. The system according to claim 8 wherein one of the entities is a service/dealership department that updates service procedures and scheduling service for the vehicle.

12. The system according to claim 8 wherein one of the entities is a customer relations department that performs prognosis and predictive vehicle maintenance, makes warranty decisions, produces product recalls and provides remote vehicle diagnosis.

13. The system according to claim 8 wherein one of the entities is vehicle production that performs vehicle assembly testing, updates assembly processes and provides production planning.

14. The system according to claim 8 further comprising a distributed database that stores the collected information to be assessable to the supplier management sub-system, the product development management sub-system, the service/dealership management sub-system, the customer relations sub-system and the production sub-system for future vehicles.

15. A method for integrating diagnosis and prognosis information, wherein the method is performed by a processor instructed to execute a program stored on a non-transitory computer-readable medium, said method comprising:

collecting on-board and off-board diagnosis and prognosis data about vehicle sub-systems and components from vehicle assembly until vehicle end of life, wherein the data is collected from a plurality of sources and relates to one or more vehicles;

providing the collected information to supplier management that takes certain actions depending on the collected information;

providing the collected information to product development management that takes certain actions depending on the collected information;

providing the collected information to service/dealership management that takes certain actions depending on the collected information;

providing the collected information to customer relations departments that take certain actions depending on the collected information; and

providing the collected information to production facilities that take certain actions depending on the collected information.

16. The method according to claim 15 wherein the supplier management provides spare part scheduling and inventory management.

17. The method according to claim 15 wherein the product development management improves vehicle design, updates vehicle requirements, updates vehicle diagnosis algorithms, updates system validations and provides remote software downloads.

18. The method according to claim 15 wherein the service/dealership management updates service procedures and schedules service for the vehicle.

19. The method according to claim 15 wherein the customer relations performs prognosis and predictive vehicle maintenance, makes warranty decisions, produces product recalls and provides remote vehicle diagnosis.

20. The method according to claim 15 wherein the production facilities perform assembly testing, updates assembly processes and provides production planning.
