Abstract

An turn detection system is configured to determine headings or a course of a vehicle over a period of time and evaluate whether the vehicle has registered a turn based on these headings/course. In some arrangements, upon detecting a turn, sensor data may be collected to determine one or more characteristics or attributes of the turn. Such data may indicate a loss event associated with the turn and be used to calculate a probability or risk of loss given the various characteristics of the turn. These probabilities may further be applied to determine various costs and premiums.

Claims

1. A turn detection apparatus comprising:

a communication interface;

a processor; and

memory storing computer readable instructions that, when executed by the processor, cause the turn detection apparatus to;

detect a plurality of headings of a vehicle, each of the headings corresponding to a different point in time;

determine a total turn angle of a turn made by the vehicle based on the plurality of headings;

determine a turn direction of the vehicle based on the total turn angle;

determine at least one characteristic of the turn of the vehicle based on one or more sensor readings associated with the vehicle; and

determine a risk of loss associated with at least one of the vehicle and a driver of the vehicle based on the determined at least one characteristic of the turn.

2. The turn detection apparatus of claim 1, wherein the communication interface includes a mobile communication device.

3. The turn detection apparatus of claim 1, wherein the communication interface is configured to be physically connected to the vehicle, and

wherein the turn detection apparatus includes at least one sensor from which the one or more sensor readings are obtained.

4. The turn detection apparatus of claim 1, wherein determining the plurality of headings of the vehicle is performed using signal triangulation.

5. The turn detection apparatus of claim 1, wherein the turn detection apparatus is further caused to determine that the vehicle has registered the turn based on the total turn angle being above a specified threshold angle.

6. The turn detection apparatus of claim 1, wherein the at least one characteristic of the turn of the vehicle includes a speed of the turn.

7. The turn detection apparatus of claim 6, wherein the at least one characteristic of the turn includes a rate of acceleration.

8. The turn detection apparatus of claim 3, wherein the at least one sensor includes a camera.

9. The turn detection apparatus of claim 1, wherein determining the risk of loss includes calculating a probability of loss based on historical loss data associated with turns having the at least one characteristic.

10. The turn detection apparatus of claim 1, wherein the turn detection apparatus is further caused to:

detect a loss event within a predefined amount of time of a turn of the vehicle; and

assign a value of the loss event to at least one characteristic of the turn.

11. The turn detection apparatus of claim 10, wherein detecting the loss event includes determining whether the loss event is within a predefined proximity of a location of the turn.

12. The turn detection apparatus of claim 11, wherein the loss event corresponds to another vehicle different from the vehicle registering the turn.

13. A turn detection apparatus comprising:

a processor; and

memory storing computer readable instructions that, when executed by the processor, cause the turn detection apparatus to;

determine a relative signal strength between a first position detection device and a second position detection device;

upon determining that a signal strength of the first position detection device is higher, obtain, at a data collection rate, first heading information for a vehicle from the first position detection device;

determine a first heading based on the received first heading information;

determine that a detection strength of the first position detection device has changed;

in response to the change in the detection strength, modify the data collection rate from the first position detection device; and

receive second heading information for the vehicle based on the modified data collection rate.

14. The turn detection apparatus of claim 13, wherein the first position detection device is a global positioning system (GPS) receiver.

15. The turn detection apparatus of claim 14, wherein the second position detection device is a cellular communication device.

16. The turn detection apparatus of claim 13, wherein modifying the data collection rate includes:

increasing a data collection rate of the first position detection device; and

decreasing a data collection rate of the second position detection device.

17. A non-transitory computer readable medium storing computer readable instructions that, when executed by a processor, cause a turn detection apparatus to:

detect a plurality of headings of a vehicle, each of the headings corresponding to a different point in time;

determine a total turn angle of a turn made by the vehicle based on the plurality of headings;

determine a turn direction of the vehicle based on the total turn angle;

determine at least one characteristic of the turn of the vehicle based on one or more sensor readings associated with the vehicle; and

determine a risk of loss associated with at least one of the vehicle and a driver of the vehicle based on the determined at least one characteristic of the turn.

18. The non-transitory computer readable medium of claim 17, wherein the turn detection apparatus is further caused to determine whether the vehicle has turned based on whether the total turn angle is above a specified threshold angle.

19. The non-transitory computer readable medium of claim 17, wherein the at least one characteristic includes a rate of acceleration.

20. The non-transitory computer readable medium of claim 17, wherein the one or more sensor readings is obtained from a camera.
