Abstract

In one embodiment, a system and method may collect acceleration data for a driver for a vehicle, compare the acceleration data for the driver to a set of acceleration data representing a plurality of sample drivers driving in the same type of vehicle as the vehicle, and based on the comparison, determining a driving style rating for the driver.

Claims

1. A method comprising:

collecting acceleration data for a vehicle being driven by a driver;

comparing acceleration data for the vehicle being driven by the driver to a set of acceleration data representing a plurality of sample drivers driving in the same type of vehicle as the vehicle;

based on the comparison, determining a driving style rating for the driver; and

displaying the driving style rating.

2. The method of claim 1 wherein collecting acceleration data comprises collecting acceleration data from an accelerometer in the vehicle.

3. The method of claim 1 wherein collecting acceleration data comprises collecting acceleration data from an accelerometer in the vehicle during a specific driving trip, and wherein the data representing a plurality of sample drivers is collected during prior driving drips.

4. The method of claim 1 wherein the vehicle is an automobile.

5. The method of claim 1, wherein collecting acceleration data comprises collecting acceleration during a specific driving trip, the method comprising:

comparing acceleration data for the vehicle driven by the driver to previous acceleration data for the vehicle driven by the driver; and

displaying the comparison.

6. The method of claim 1, comprising comparing acceleration data for the vehicle driven by the driver in each of a plurality of speed bands to acceleration data for the sample drivers in each of a plurality of corresponding speed bands.

7. The method of claim 1, wherein comparing comprises subtracting the mean of acceleration data for sample drivers from the mean of acceleration data for the driver driving the vehicle.

13. The device of claim 1, wherein the controller is to compare acceleration data for the vehicle driven by the driver in each of a plurality of speed bands to acceleration data for the sample drivers in each of a plurality of corresponding speed bands.

14. The device of claim 1, wherein comparing comprises subtracting the mean of acceleration data for sample drivers from the mean of acceleration data for the driver driving the vehicle.

8. A device comprising:

a memory; and

a controller to;

accept acceleration data for a vehicle being driven by a driver;

compare the acceleration data for the vehicle being driven by the driver to a set of acceleration data representing a plurality of sample drivers driving in the same type of vehicle as the vehicle; and

based on the comparison, determine a driving style rating for the driver.

9. The device of claim 8 wherein collecting acceleration data comprises collecting acceleration data from an accelerometer in the vehicle.

10. The device of claim 8 wherein collecting acceleration data comprises collecting acceleration data from an accelerometer in the vehicle during a specific driving trip, and wherein the data representing a plurality of sample drivers is collected during prior driving drips.

11. The device of claim 8 wherein the vehicle is an automobile.

12. The device of claim 8, wherein collecting acceleration data comprises collecting acceleration during a specific driving trip, wherein the controller is to compare acceleration data for the vehicle driven by the driver to previous acceleration data for vehicle driven by the driver.

15. A method comprising:

subtracting an average of acceleration data values for a set of drivers driving a type of vehicle from an average of acceleration data values for a specific vehicle of the type when driven by a current driver to produce an interim rating;

dividing the interim rating by a standard deviation of the acceleration data for a set of drivers driving the type of vehicle to produce a rating;

further processing the rating; and

providing the processed rating to the current driver.

16. The method of claim 15 comprising collecting acceleration data from an accelerometer in the specific vehicle.

17. The method of claim 15 wherein the specific vehicle is an automobile.

18. The method of claim 15, comprising determining a rating for each of a plurality of speed ranges.

19. The method of claim 18, comprising averaging the ratings for each of a plurality of speed ranges.

20. The method of claim 15, wherein further processing comprises multiplying the rating by the square root of the number of samples collected for the current driver.
