Abstract

A computing device for a vehicle fluid replacement monitoring system is provided. The computing device includes one or more processors for controlling operation of the computing device, and a memory for storing data and program instructions usable by the one or more processors. The one or more processors are configured to execute instructions stored in the memory to receive an indication of a “fluid-empty” condition in a fluid reservoir; receive an indication of a “fluid-present” condition occurring in the fluid reservoir after the “fluid-empty” condition; acquire, responsive to receiving the indication of the “fluid-present” condition, information relating to the “fluid-present” condition; and store, in a memory, the information relating to the “fluid-present” condition.

Claims

1. A computing device for a fluid replacement monitoring system in a vehicle, the computing device comprising one or more processors residing on the vehicle for controlling operation of the computing device, and a memory residing on the vehicle for storing data and program instructions usable by the one or more processors, wherein the one or more processors are configured to execute instructions stored in the memory to:

receive an indication of a “

fluid-empty”

condition in a fluid reservoir of the vehicle;

receive an indication of a “

fluid-present”

condition occurring in the fluid reservoir of the vehicle after the indication of the “

fluid-empty”

condition in the fluid reservoir was received;

acquire, responsive to receiving the indication of the “

fluid-present”

condition, information indicative of a location of the vehicle when the indication of the “

fluid-present”

condition in the fluid reservoir of the vehicle was received; and

store, in the memory residing on the vehicle, the information indicative of a location of the vehicle when the indication of the “

fluid-present”

condition was received.

2. The computing device of claim 1 wherein the one or more processors are configured to execute instructions stored in the memory to correlate the information relating to the “

fluid-present”

condition.

3. The computing device of claim 1 wherein the one or more processors are configured to execute instructions stored in the memory to:

compare the information indicative of the location of the vehicle when the indication of the “

fluid-present”

condition was received with coordinates or other location information relating to points of interest; and

determine if the information indicative of the location of the vehicle when the indication of the “

fluid-present”

condition was received matches information relating to the points of interest.

4. The system of claim 3 wherein the location information relating to points of interest is stored in the memory residing on the vehicle and include any of a vehicle owner'"'"'s home, an approved vehicle service facility, and a third party service facility.

5. The computing device of claim 3 wherein, the one or more processors are configured to execute instructions stored in the memory to, if there is a match between the information indicative of the location of the vehicle when the indication of the “

fluid-present”

condition was received and location information relating to the points of interest, integrate location information relating to the points of interest with the information indicative of the location of the vehicle when the indication of the “

fluid-present”

condition was received, by adding to the memory the information indicative of the location of the vehicle when the indication of the “

fluid-present”

condition was received.

6. The computing device of claim 5 wherein the one or more processors are configured to execute instructions stored in the memory to, if additional information relating to the location of the vehicle when the indication of the “

fluid-present”

condition was received is available, integrate the additional information with the information indicative of the location of the vehicle when the indication of the “

fluid-present”

condition was received, by adding the additional information to the memory.

7. The computing device of claim 1 wherein the one or more processors are configured to execute instructions stored in the memory to acquire, responsive to receiving the indication of the “

fluid-present”

condition, information indicative of a calendar date when the indication of the “

fluid-present”

condition was received.

8. The computing device of claim 1 wherein the one or more processors are configured to execute instructions stored in the memory to acquire, responsive to receiving the indication of the “

fluid-present”

condition, information indicative of a time of day when the indication of the “

fluid-present”

condition was received.

9. The computing device of claim 1 wherein the one or more processors are configured to execute instructions stored in the memory to maintain, in a memory and for each type of fluid for which an indication of a “

fluid-present”

condition is received, a running total of a number of “

fluid-present”

condition occurrences detected in an associated fluid reservoir.

10. A method of monitoring vehicle fluid changes in a vehicle, comprising steps of:

mounting, on the vehicle, a computing device configured to acquire and store information relating to fluid changes in the vehicle;

detecting, in a fluid reservoir of the vehicle, an occurrence of a “

fluid-empty”

condition;

detecting, in the fluid reservoir of the vehicle, a “

fluid-present”

condition occurring after the occurrence of the “

fluid-empty”

condition;

acquiring, by the computing device after detection of the “

fluid-present”

condition, information relating to a location of the vehicle when the “

fluid-present”

condition was detected; and

storing, in a memory of the computing device, the information relating to the location of the vehicle when the “

fluid-present”

condition was detected.

11. The method of claim 10 further comprising the step of, prior to the step of storing the information relating to the detected “

fluid-present”

condition, correlating the information relating to the detected “

fluid-present”

condition.

12. The method of claim 10 further comprising the steps of:

comparing information relating to the location of the vehicle when the “

fluid-present”

condition was detected with location information relating to points of interest; and

if the information relating to the location of the vehicle when the “

fluid-present”

condition was detected matches the location information relating to any of the points of interest, integrating the matching point of interest location information with the information relating to the location of the vehicle when the “

fluid-present”

condition was detected by adding to the memory the information relating to the location of the vehicle when the “

fluid-present”

condition was detected.

13. The method of claim 12 further comprising the step of, if additional information relating to the location of the vehicle when the “

fluid-present”

condition was detected is available, integrating the additional information with the information relating to the location of the vehicle when the “

fluid-present”

condition was detected by adding to the memory the additional information.

14. The method of claim 12 wherein the points of interest include any of a vehicle owner'"'"'s home, an approved vehicle service facility, and a third party service facility.
