Abstract

The present invention allows advanced diagnostics to be loaded into a vehicle on demand with results being sent back to the diagnostic center, possibly requiring a more refined selection of diagnostics based on the results of the previous tests. Thus, a new generation of network vehicle communications with diagnostic centers, via cellular telephone, wireless communications and Internet access via wireless communication link, provide a rich networking topology that allows onboard computers or microprocessors to obtain problem diagnosis information and data while on the road.

Claims

1. A method for performing diagnostic analysis on a vehicle, employing said vehicle'"'"'s on-board computer;

comprising the steps of;

providing computer communication and interaction between said vehicle'"'"'s on-board computer and a diagnostic center'"'"'s computer;

transmitting initial diagnostic information, from said vehicle'"'"'s on-board computer, to said diagnostics center'"'"'s computer, for advanced diagnostic analysis;

receiving in response to said transmission from said vehicle'"'"'s on-board computer, to said diagnostic center'"'"'s computer, advanced diagnostic routines for further processing by said vehicle'"'"'s on-board computer;

repeating said transmission and said receiving process, until said vehicle'"'"'s on-board computer determines that the desired diagnostic results are attained.

2. The method of claim 1 wherein said transmitting from said vehicle and said transmitting from said diagnostics center, are accomplished via any one of a wireless and wired communication means.

3. The method of claim 1 further comprising the step of:

self initiation by a server, connected to the diagnostic center'"'"'s computer, for delivery of said diagnostic information to said vehicle'"'"'s computer.

4. The method of claim 1 further comprising the steps of:

providing a docking station in said vehicle;

mounting a computer in said vehicle, employing said docking station; and

employing said computer in said vehicle'"'"'s docking station as said on-board computer, to perform the initial diagnostic evaluation before sending results to the diagnostic center'"'"'s computer for advanced diagnostic analysis.

5. The method of claim 1 further comprising the steps of:

employing a portable PC in said vehicle as the on-board computer to perform initial diagnostic evaluation before sending results to the diagnostic center'"'"'s computer for advanced diagnostic analysis; and

interacting said portable PC in said vehicle, with said diagnostic center'"'"'s computer system.

6. The method of claim 1 further comprising the steps of:

allowing progressively more said advanced diagnostics to request more complete analysis on certain parts of the vehicle; and

pinpointing for said vehicle'"'"'s on-board computer, problem areas as a result of said more advanced diagnostics.

7. A system for performing diagnostic analysis on a vehicle, employing said vehicle'"'"'s on-board computer;

comprising;

means for establishing computer communication and interaction, between said vehicle'"'"'s on-board computer and a diagnostic center'"'"'s computer;

means for transmitting initial diagnostic information from said vehicle'"'"'s on-board computer, to said diagnostics center'"'"'s computer, for further advanced diagnostic analysis; and

receiving, in response, advanced diagnostic routines, from said diagnostic center'"'"'s computer, for further processing by said vehicle'"'"'s on-board computer; and

means for repeating said transmission and said receiving process, until said vehicle'"'"'s on-board computer determines that the desired diagnostic results are attained.

8. The system of claim 7 further comprising a means for providing more advanced diagnostic routines into said vehicle'"'"'s on-board computer.

9. The system of claim 7 wherein said diagnostic information delivered to said vehicle, from said diagnostic center, occurs at the initiation of a server connected to the diagnostic center'"'"'s computer.

10. The system of claim 7 wherein said on-board computer in said vehicle is employed in a docking station mounted in said vehicle.

11. The system of claim 7 further comprising means for providing advanced diagnostic routines, on demand, into said on-board computer, without the need to continually store said routines inboard said vehicle.

12. The system of claim 7 further comprising means for progressively performing more advanced diagnostics and to request more complete analysis on certain parts of said vehicle, in order to pinpoint problem areas.

13. A computer program product, having a programmable code included on a computer readable medium for, performing diagnostic analysis on a vehicle, employing said vehicle'"'"'s own on-board computer;

comprising;

means for establishing computer communication and interaction, between said vehicle'"'"'s on-board computer and a diagnostic center'"'"'s computer;

means for transmitting initial diagnostic information from said vehicle'"'"'s on-board computer, to said diagnostics center'"'"'s computer, for further advanced diagnostic analysis; and

receiving, in response, advanced diagnostic routines, from said diagnostic center'"'"'s computer, for further processing by said vehicle'"'"'s on-board computer; and

means for repeating said transmission and said receiving process, until said vehicle'"'"'s on-board computer determines that the desired diagnostic results are attained.

14. The computer program product of claim 13 further comprising means for providing more advanced diagnostic routines into said vehicle'"'"'s on-board computer.

15. The computer program product of claim 13 wherein said diagnostic information delivered to said vehicle, from said diagnostic center, occurs at the initiation of a server connected to said diagnostic center'"'"'s computer.

16. The computer program product of claim 13 wherein said computer in said vehicle is employed using a docking station mounted in said vehicle.

17. The computer program product of claim 13 further comprising means for providing advanced diagnostic routines, on demand, to said vehicle'"'"'s on-board computer without the need to continually store said routines inboard said vehicle.

18. The computer program product of claim 13 further comprising means for performing more advanced diagnostics and to request more complete analysis on certain parts of the vehicle, in order to pinpoint a specific problem.
