Abstract

A data logging unit configured for installation in a hybrid vehicle communicates with a user device configured to receive data from the data logging unit and to display selected portions of the data to a user for identification of potential vehicle faults associated with vehicle events reported by the vehicle'"'"'s driver. The data logging unit has a data logger which communicates with hybrid drive system and other vehicle components to receive hybrid drive system data, and with a vehicle position sensor which detects location to receive vehicle location data. A data log processing module correlates location data with the corresponding vehicle data, and creates a correlated log of drive system data and associated vehicle location information, to allow identification of vehicle data within an event window based on vehicle location at the time of a reported event. Accordingly, a user may make a geographical request and the system will report vehicle data corresponding to the geographical request.

Claims

1. A remote diagnostic system for a hybrid drive system in a hybrid-electric vehicle, the remote diagnostic system comprising:

a memory in which hybrid drive data and vehicle location data is recorded;

a user interface configured to receive a geographical request; and

,

a processor configured to determine a subset of the hybrid drive system data in response to the geographical request, and further configured to report the subset of the hybrid drive system data.

2. The remote diagnostic system of claim 1, further comprising a graphical user interface configured to display geographical information associated with the vehicle location data.

3. The remote diagnostic system of claim 2, wherein the graphical user interface is further configured to provide a selection range for the geographical request.

4. The remote diagnostic system of claim 3, wherein the selection range includes one or more vehicle location points associated with the vehicle location data.

5. The remote diagnostic system of claim 4, wherein the graphical user interface is further configured to provide key status information associated with one or more vehicle location points.

6. The remote diagnostic system of claim 5, wherein the key status information includes at least one of:

a fault flag, a time, an energy storage status, and a high voltage isolation status.

7. The remote diagnostic system of claim 5, wherein the user interface is further configured to receive a key status information request;

and,

wherein the key status information is selected responsive to the key status information request.

8. The remote diagnostic system of claim 4, wherein the geographical request comprises a vehicle location point request;

and,

wherein the processor is further configured to determine an event window responsive to the vehicle location point request, the event window defining the geographical request as those vehicle location data occurring within a predetermined time before and after the vehicle location point request, and/or as those vehicle location data occurring within a predetermined distance before and after the vehicle location point request.

9. The remote diagnostic system of claim 2, wherein the geographical information associated with the vehicle location data includes then current environmental conditions proximate the hybrid-electric vehicle.

10. The remote diagnostic system of claim 2, wherein the graphical user interface is further configured to display available data sources associated with the hybrid drive system data.

11. The remote diagnostic system of claim 10, wherein the user interface is further configured to receive a data source request;

and,

wherein the subset of the hybrid drive system data is determined in accordance with the data source request.

12. The remote diagnostic system of claim 2, wherein the user interface is further configured to receive a time request;

and,

wherein the graphical user interface is further configured to display a subset of the vehicle location data in response to the time request.

13. The remote diagnostic system of claim 1, wherein the memory is located onboard the hybrid electric vehicle, the remote diagnostic system further comprising a receiver configured to receive wireless communications containing hybrid drive data and vehicle location data from the memory onboard the vehicle.

14. A method for remotely diagnosing a hybrid drive system in a hybrid-electric vehicle, the method comprising:

recording a hybrid drive data and a vehicle location data;

identifying geographical information to a user;

receiving a geographical request from the user;

determining a subset of the hybrid drive system data in response to the geographical request from the user;

reporting the subset of the hybrid drive system data to the user.

15. The method of claim 14, further comprising correlating the hybrid drive data with the vehicle location data.

16. The method of claim 14, wherein the identifying geographical information to a user comprises providing a selection range to the user that includes one or more vehicle location points associated with the vehicle location data.

17. The method of claim 16, wherein the geographical request comprises a vehicle location point request, the method further comprising determining an event window responsive to the vehicle location point request, the event window defining the geographical request as those vehicle location data occurring within a predetermined time before and after the vehicle location point request, and/or as those vehicle location data occurring within a predetermined distance before and after the vehicle location point request.

18. The method of claim 14, further comprising providing key status information to the user, the key status information associated with one or more vehicle location points.

19. The method of claim 18, wherein the key status information includes at least one of:

a fault flag, a time, an energy storage status, and a high voltage isolation status.

20. The method of claim 18, further comprising receiving a key status information request from the user;

and,

wherein the providing key status information to the user is determined in accordance with the key status information request.
