Abstract

A method is provided for determining a vehicle lifetime fuel economy using a remote server. The method includes retrieving from at least one vehicle control module vehicle data including an amount of total fuel used by the vehicle, determining whether the total fuel used by the vehicle is greater than or equal to a stored fuel used value, calculating an adjusted total fuel used if the total fuel used is not greater than or equal to the stored fuel used value, and calculating the lifetime fuel economy based on the adjusted total fuel used.

Claims

1. A method for determining a vehicle lifetime fuel economy using a remote server, the method comprising the steps of:

retrieving from at least one vehicle control module vehicle data including an amount of total fuel used by the vehicle;

determining whether the total fuel used by the vehicle is greater than or equal to a stored fuel used value;

calculating an adjusted total fuel used if the total fuel used is not greater than or equal to the stored fuel used value; and

calculating the lifetime fuel economy based on the adjusted total fuel used.

2. The method of claim 1, wherein the vehicle data further includes a total number of miles driven.

3. The method of claim 2, further comprising calculating a standard lifetime fuel economy based on the total fuel used by the vehicle and the number of total miles driven if the total fuel used is greater than or equal to the stored fuel used value.

4. The method of claim 3, further comprising storing the total fuel used from the standard lifetime fuel economy calculation in a remote database.

5. The method of claim 3, wherein the total fuel used from the standard lifetime fuel economy calculation is saved as the stored fuel used in a remote database.

6. The method of claim 1, further comprising the step of receiving a lifetime fuel economy request from a mobile device.

7. The method of claim 6, wherein mobile device includes a software application in communication with the remote server.

8. The method of claim 7, further comprising transmitting the calculated lifetime fuel economy to the software application.

9. The method of claim 1, further comprising the step of computing the adjusted total fuel used by adding the stored fuel used value to the total fuel used by the vehicle.

10. The method of claim 1, wherein the lifetime fuel economy is calculated by dividing the number of miles driven by the adjusted total fuel used.

11. The method of claim 1, further comprising the step of receiving a lifetime fuel economy request from a software application.

12. A system for determining a vehicle lifetime fuel economy, the system comprising:

a remote server in communication with at least one vehicle control module and a mobile device, the remote server configured to;

retrieve from the at least one vehicle control module vehicle data including an amount of total fuel used by the vehicle;

determine whether the total fuel used by the vehicle is greater than or equal to a stored fuel used value;

calculate an adjusted total fuel used if the total fuel used is not greater than or equal to the stored fuel used value; and

calculate the lifetime fuel economy based on the adjusted total fuel used.

13. The system of claim 12, wherein the vehicle data further includes a total number of miles driven.

14. The system of claim 13, further comprising calculating a standard lifetime fuel economy based on the total fuel used by the vehicle and the number of total miles driven if the total fuel used is greater than or equal to the stored fuel used value.

15. The system of claim 14, further comprising storing the total fuel used from the standard lifetime fuel economy calculation in a remote database.

16. The system of claim 14, wherein the total fuel used from the standard lifetime fuel economy calculation is saved as the stored fuel used value in a remote database.

17. The system of claim 12, wherein the remote server is further configured to receive a lifetime fuel economy request from an application.

18. The system of claim 17, wherein the application resides on the mobile device.

19. The system of claim 12, wherein the remote server is further configured to compute the adjusted total fuel used by adding the stored fuel used value to the total fuel used by the vehicle.

20. The system of claim 12, wherein the lifetime fuel economy is calculated by dividing the number of total miles driven by the adjusted total fuel used.
