Abstract

Vehicle telematics is employed to improve maintenance scheduling by facilitating collection and integration of vehicle condition information from diverse sources. These sources include real time data collected from vehicle sensors over an intelligent vehicle controller area network. The network is provided with facilities for generating records with stamps allowing their correlation with vehicle inspection results and the generation of trend reports to be used in scheduling maintenance.

Claims

1. A data integration system for motor vehicle service scheduling, the data integration system comprising:

a central data repository;

an integrated data network and sensor package installed on at least a first motor vehicle for generating vehicle data;

a vehicle service facility for periodically inspecting motor vehicles including the first motor vehicle and generating inspection data;

vehicle fluid analytical services for analyzing fluid samples drawn from the first motor vehicle and generating data relating to the results of the analysis;

data communication facilities for coupling the various data generated by the integrated data network and sensor package, at the vehicle service facility and through the vehicle fluid analytical services to the central data collection facility;

the central data repository including database services for facilitating organized recordation and retrieval of the data for comparison analysis; and

a website generated by the central data repository for display of results from the comparison analysis.

2. A data integration system as set forth in claim 1, the data communication facilities further comprising:

a radio-based link facilitating real time transfer of vehicle data to a central sever computer as part of a vehicular telematics package.

3. A data integration system as set forth in claim 2, further comprising:

standardized sampling containers for transferring fluid samples drawn from vehicles at the vehicle service facility for transfer to the vehicle fluid analytical services.

4. A data integration system as set forth in claim 2, the integrated data network and sensor package further comprising:

a public vehicle controller area network;

a vehicle body computer;

a plurality of controllers coupled for communication with the vehicle body computer over the public vehicle controller area network;

a private vehicle controller area network; and

communication and position locating facilities coupled to the vehicle body computer over the private controller area network to enable stamping of records for forwarding to the central data repository.

5. A data integration system as set forth in claim 4, further comprising:

a plurality of sensors, each sensor being coupled to one of the plurality of controllers.

6. A data integration system as set forth in claim 5, further comprising:

the vehicle body computer being programmed to execute engine oil condition prediction routines.

7. A data integration system as set forth in claim 6, further comprising:

the data communication facility between the vehicle fluid analytical services and the central data repository including a website on which the data generated by the vehicle fluid analytical services is placed for retrieval.

8. A data integration system as set forth in claim 7, further comprising:

means associated with the central data repository for determining service intervals for the at least first motor vehicle.

9. A method of determining motor vehicle service intervals, the method comprising the steps of:

providing a central data repository;

collecting data relating to vehicle operating variables generated by sensors installed on a selected motor vehicle;

selecting data from the collected data and forwarding the selected data to the central data repository on a real time basis;

periodically inspecting the selected motor vehicle at a service facility;

making the results of the periodic inspections at the service facility available to the central data repository;

as part of the periodic inspection drawing fluid samples from the selected motor vehicle;

sending the fluid samples to fluid analytical services for component analysis;

making the resulting data from the component analysis available to the central data repository; and

determining from the data collected at the central data repository a service interval for the selected motor vehicle.

10. A method of determining motor vehicle service intervals as set forth in claim 9, the service interval-determining step further comprising the steps of:

organizing the collected data into databases relating to the selected motor vehicle; and

generating trend lines over time or mileage for vehicle operating variable value and at least a first possible cause of the trend.

11. A method of determining motor vehicle service intervals as set forth in claim 10, further comprising the step of:

generating displays of the trend lines to system operators for determinations regarding service intervals.

12. A method of determining motor vehicle service intervals as set forth in claim 10, further comprising the step of:

comparing trend lines against predetermined norms for determining service intervals.

13. A method of determining motor vehicle service intervals as set forth in claim 12, the steps of making data available to the central data repository including the step of posting the data to websites for access by the central data repository.

14. A method of determining motor vehicle service intervals as set forth in claim 13, further comprising the step of:

generating a vehicle State-of-Health score as a weighted score of the faults, component condition and performance compared against standards.

15. A method of determining motor vehicle service intervals, further comprising the steps of:

recording time and location occurrences of out-of-limits vehicle operation including excessive speed and braking in the database; and

correlating out of limits operation with out of record time and location occurrences of out-of-limits operation.
