Abstract

A method and system are provided for generating prognostic information regarding a component in a vehicle. The method includes receiving a first set of data for one or more parameters corresponding to the component. The first set of data is obtained from a degradation signal wirelessly transmitted from the vehicle at a first predetermined frequency. The method further includes executing, at a second predetermined frequency, a set of executable instructions for assessing a condition of the component in response to the first set of data. The method further includes obtaining a second set of data indicative of repair or replacement of the component and adjusting at least one of the first predetermined frequency and the second predetermined frequency responsive to the second set of data.

Claims

1. A system for generating prognostic information regarding a component in a first vehicle, comprising:

a memory configured to store a set of executable instructions for assessing a condition of the component in response to a first set of data for one or more parameters corresponding to the component obtained from a degradation signal wirelessly transmitted from the first vehicle at a first predetermined frequency;

a processor configured to;

execute, at a second predetermined frequency, the set of executable instructions;

obtain a second set of data indicative of repair or replacement of the component; and

,

adjust at least one of the first predetermined frequency and the second predetermined frequency responsive to the second set of data.

2. The system of claim 1 wherein the processor is further configured, in adjusting the at least one of the first predetermined frequency and the second predetermined frequency, to reduce the at least one of the first predetermined frequency and the second predetermined frequency.

3. The system of claim 2 wherein the at least one of the first predetermined frequency and the second predetermined frequency comprises the first predetermined frequency and the processor is further configured, in reducing the at least one of the first predetermined frequency and the second predetermined frequency predetermined frequency to generate a control signal for transmission to the first vehicle, the control signal configured to prevent transmission of the degradation signal by the first vehicle.

4. The system of claim 2 wherein the at least one of the first predetermined frequency and the second predetermined frequency comprises the second predetermined frequency and the processor is further configured, in reducing the at least one of the first predetermined frequency and the second predetermined frequency to prevent execution of the set of executable instructions for a period of time.

5. The system of claim 1 wherein the at least one of the first predetermined frequency and the second predetermined frequency comprises the first predetermined frequency and the processor is further configured to generate a control signal for transmission to the first vehicle, the control signal configured to adjust the first predetermined frequency.

6. The system of claim 1 wherein the processor is further configured, in obtaining the second set of data, to extract the second set of data from the degradation signal.

7. The system of claim 1 wherein the processor is further configured to periodically request data regarding the first vehicle from a database configured to retain maintenance records for a plurality of vehicles including the first vehicle when execution of the set of executable instructions indicates that the condition of the component meets a predetermined condition.

8. A system for generating prognostic information regarding a component in a first vehicle, comprising:

a memory configured to store a set of executable instructions for assessing a condition of the component in response to a first set of data for one or more parameters corresponding to the component obtained from a degradation signal wirelessly transmitted from the first vehicle at a first predetermined frequency;

a processor configured to;

execute, at a second predetermined frequency, the set of executable instructions;

obtain a second set of data indicative of repair or replacement of the component from a database configured to retain maintenance records for a plurality of vehicles including the first vehicle; and

,

adjust at least one of the first predetermined frequency and the second predetermined frequency responsive to the second set of data.

9. The system of claim 8 wherein the processor is further configured, in adjusting the at least one of the first predetermined frequency and the second predetermined frequency, to reduce the at least one of the first predetermined frequency and the second predetermined frequency.

10. The system of claim 9 wherein the at least one of the first predetermined frequency and the second predetermined frequency comprises the first predetermined frequency and the processor is further configured, in reducing the at least one of the first predetermined frequency and the second predetermined frequency predetermined frequency to generate a control signal for transmission to the first vehicle, the control signal configured to prevent transmission of the degradation signal by the first vehicle.

11. The system of claim 9 wherein the at least one of the first predetermined frequency and the second predetermined frequency comprises the second predetermined frequency and the processor is further configured, in reducing the at least one of the first predetermined frequency and the second predetermined frequency to prevent execution of the set of executable instructions for a period of time.

12. The system of claim 8 wherein the at least one of the first predetermined frequency and the second predetermined frequency comprises the first predetermined frequency and the processor is further configured to generate a control signal for transmission to the first vehicle, the control signal configured to adjust the first predetermined frequency.

13. The system of claim 8 wherein the processor is further configured to periodically request data regarding the first vehicle from the database when execution of the set of executable instructions indicates that the condition of the component meets a predetermined condition.

14. A method for generating prognostic information regarding a component in a first vehicle, comprising the steps of:

receiving a first set of data for one or more parameters corresponding to the component, the first set of data obtained from a degradation signal wirelessly transmitted from the first vehicle at a first predetermined frequency;

executing, at a second predetermined frequency, a set of executable instructions for assessing a condition of the component in response to the first set of data;

obtaining a second set of data indicative of repair or replacement of the component; and

,

adjusting at least one of the first predetermined frequency and the second predetermined frequency responsive to the second set of data.

15. The method of claim 14 wherein the adjusting the at least one of the first predetermined frequency and the second predetermined frequency comprises reducing the at least one of the first predetermined frequency and the second predetermined frequency.

16. The method of claim 15 wherein the at least one of the first predetermined frequency and the second predetermined frequency comprises the first predetermined frequency and adjusting the at least one of the first predetermined frequency and the second predetermined frequency includes the substep of generating a control signal for transmission to the first vehicle, the control signal configured to prevent transmission of the degradation signal by the first vehicle.

17. The method of claim 15 wherein the at least one of the first predetermined frequency and the second predetermined frequency comprises the second predetermined frequency and reducing the at least one of the first predetermined frequency and the second predetermined frequency includes preventing execution of the set of executable instructions for a period of time.

18. The method of claim 14 wherein the obtaining the second set of data includes the substep of receiving the second set of data from a database configured to retain maintenance records for a plurality of vehicles including the first vehicle.

19. The method of claim 14 wherein obtaining the second set of data includes the substep of extracting the second set of data from the degradation signal.
