Abstract

A computer implemented method for determining one or more idling time windows from a vehicle trip is presented. A data server may receive, via a computer network, a plurality of telematics data originating from a client computing device and identify primary movement data from the plurality of telematics data. The data server may also measure a total variance from the plurality of telematics data at one or more time stamps and determine an average total variance for an entire trip from the plurality of telematics data. The data server may further normalize total variance at the one or more time stamps using the generated average and determine one or more idling time windows from the normalized total variance.

Claims

1. A computer implemented method for determining one or more idling time windows from a vehicle trip, the method comprising:

receiving, via a computer network, a plurality of telematics data originating from a client computing device placed in a vehicle;

identifying, by one or more processors, a primary movement window from the plurality of telematics data, wherein the primary movement window is indicative of the client computing device being static with respect to the moving vehicle;

measuring, by the one or more processors, a total variance from the plurality of telematics data at one or more time stamps in the primary movement window;

determining, by the one or more processors, an average signal total variance from the plurality of telematics data in the primary movement window;

normalizing, by the one or more processors, the total variance at the one or more time stamps using the generated average; and

determining, by the one or more processors, one or more idling time windows from the normalized total variance, wherein each of the idling time windows indicate a period of time when the vehicle is not moving.

2. The method of claim 1 further comprising:

determining, by the one or more processors, an auto insurance risk using at least the one or more idling time windows.

3. The method of claim 1 further comprising:

correlating, by the one more processors, the one or more idling time windows with an additional idling time data source.

4. The method of claim 1, further comprising:

comparing, by the one or more processors, the total variance data to a threshold value.

5. The method of claim 1, wherein the telematics data is measured at a first resolution measuring the total variance further comprises:

grouping, by the one or more processors, the plurality of telematics data to a second resolution that is lower than the first resolution at which the plurality of telematics data was measured.

6. The method of claim 1, wherein measuring the total variance further comprises:

reducing, by the one or more processors, one or more primary moving windows from the plurality of telematics data.

19. The method of claim 1 further comprising:

determining, by the one or more processors, a driving pattern corresponding to a driving environment of the vehicle based on the frequency of the idling time windows.

7. A computer device for determining one or more idling time windows from a vehicle trip, the device comprising:

one or more processors; and

one or more memories coupled to the one or more processors;

the one or more memories including non-transitory computer executable instructions stored therein that, when executed by the one or more processors, cause the one or more processors to;

receive a plurality of telematics data originating from a client computing device placed in a vehicle;

identify a primary movement window from the plurality of telematics data, wherein the primary movement window is indicative of the client computing device being static with respect to the moving vehicle;

measure a total variance from the plurality of telematics data at one or more time stamps in the primary movement window;

determine an average signal total variance from the plurality of telematics data in the primary movement window;

normalize the total variance at the one or more time stamps using the generated average; and

determine one or more idling time windows from the normalized total variance, wherein each of the idling time windows indicate a period of time when the vehicle is not moving.

8. The computer device of claim 7, wherein the non-transitory computer executable instructions further cause the one or more processors to:

determine an auto insurance risk using at least the one or more determined idling time windows.

9. The computer device of claim 7, wherein the non-transitory computer executable instructions further cause the one or more processors to:

correlate the one or more idling time windows with an additional idling time data source.

10. The computer device of claim 7, wherein the non-transitory computer executable instructions further cause the one or more processors to:

compare the total variance data to a threshold value.

11. The computer device of claim 7, wherein the telematics data is measured at a first resolution the non-transitory computer executable instructions further cause the one or more processors to:

reduce the plurality of telematics data to a second resolution that is lower than the first resolution at which the plurality of telematics data was measured.

12. The computer device of claim 7, wherein the non-transitory computer executable instructions further cause the one or more processors to:

determine one or more primary moving windows from the plurality of telematics data.

13. A computer readable storage medium comprising non-transitory computer readable instructions stored thereon for determining one or more idling time windows from a vehicle trip, the instructions when executed on one or more processors cause the one or more processors to:

receive, via a computer network, a plurality of telematics data originating from a client computing device placed in a vehicle;

identify, by the one or more processors, a primary movement window from the plurality of telematics data, wherein the primary movement window is indicative of the client computing device being static with respect to the moving vehicle;

measure, by the one or more processors, a total variance from the plurality of telematics data at one or more time stamps in the primary movement window;

determine, by the one or more processors, an average signal total variance from the plurality of telematics data in the primary movement window;

normalize, by the one or more processors, the total variance at the one or more time stamps using the generated average; and

determine, by the one or more processors, one or more idling time windows from the normalized total variance, wherein each of the idling time windows indicate a period of time when the vehicle is not moving.

14. The computer readable storage medium of claim 13, comprising further instructions stored thereon that cause the one or more processors to:

determine, at the one or more processors, an auto insurance rating using at least the one or more idling time windows.

15. The computer readable storage medium of claim 13, comprising further instructions stored thereon that cause the one or more processors to:

correlate, at the one more processors, the one or more idling time windows with an additional idling time data source.

16. The computer readable storage medium of claim 13, comprising further instructions stored thereon that cause the one or more processors to:

compare, at the one or more processors, the total variance data to a threshold value.

17. The computer readable storage medium of claim 13 wherein the telematics data is measured at a first resolution, comprising further instructions stored thereon that cause the one or more processors to:

reduce, at the processor, the plurality of telematics data to a second resolution that is lower than the first resolution at which the plurality of telematics data was measured.

18. The computer readable storage medium of claim 13, comprising further instructions stored thereon that cause the one or more processors to:

determine, at the processor, one or more primary moving windows from the plurality of telematics data.
