Abstract

Claims (42)

1. A system for determining a driver log entry, comprising:

one or more onboard vehicle sensors configured to capture data from a vehicle;

a processor configured to:

determine a log start time;

determine a drive maneuver signature associated with the driver based at least in part on data from the one or more onboard vehicle sensors, wherein the drive maneuver signature comprises measurable characteristic behaviors or a recognized manner associated with performing one or more drive maneuvers;

determine a driver identity after the log start time based at least in part on the drive maneuver signature associated with the driver;

determine whether a change to the driver identity has occurred based at least in part on data from the one or more onboard vehicle sensors;

in the event that a change to the driver identity is determined to have occurred,

determine a log stop time and generate a driver log entry based at least in part on the driver identity, the log start time, and the log stop time; and

in the event that a change to the driver identity is determined to have not occurred, associated driving data with the driver identity; and

a memory coupled to the processor and configured to provide the processor with instructions.

2. The system as in claim 1 , wherein the driver identity is associated with a driving data between the log start time and the log stop time.

3. The system as in claim 2 , wherein the driving data comprises one or more of the following: a trip start time, a trip end time, a trip route, and a trip duration.

4. The system as in claim 2 , wherein the driving data comprises a drive event.

5. The system as in claim 2 , wherein the driving data comprises a drive performance assessment.

6. The system as in claim 2 , wherein the driving data comprises a safety performance.

7. The system as in claim 2 , wherein the driving data comprises a fuel efficiency performance.

8. The system as in claim 2 , wherein the driving data comprises a rule or a policy compliance performance.

9. The system as in claim 1 , wherein the log start time and the log stop time include a time of day and a date.

10. The system as in claim 1 , wherein the change to the driver identity is determined based at least in part on sensor data that comprises a detection or a measurement of one or more of the following: an ignition on state, an ignition off state, a power on state, a power off state, an engine on state, an engine off state, a new face in a cabin camera image, a new identification badge is presented, a different driving manner, and a different weight in a driver seat.

11. The system as in claim 1 , wherein the change in the driver identity is determined to have occurred while the vehicle is in operation.

12. The system as in claim 1 , wherein the new driver identity is different from the previous driver identity.

13. The system as in claim 1 , wherein the one or more drive maneuvers include at least one of the following: a right or left turn maneuver, a highway on or off ramp maneuver, a U-turn maneuver, a lane change maneuver, an acceleration maneuver, and a brake maneuver.

14. The system as in claim 1 , wherein the one or more drive maneuvers include at least one specific drive maneuver that is associated with a particular geolocation.

15. The system as in claim 1 , wherein the driver identity is further determined by applying a facial recognition algorithm to analyze driver facial images captured by the one or more onboard vehicle sensors.

16. The system as in claim 1 , wherein the driver identity is further determined based at least in part on an analysis of driver voice characteristics captured by the one or more onboard vehicle sensors.

17. A method for determining a driver log entry, comprising:

determining a log start time;

determining, using a processor, a drive maneuver signature associated with the driver based at least in part on data from the one or more onboard vehicle sensors, wherein the drive maneuver signature comprises measurable characteristic behaviors or a recognized manner associated with performing one or more drive maneuvers;

determining a driver identity after the log start time based at least in part on the drive maneuver signature associated with the driver;

determining whether a change to the driver identity has occurred based at least in part on data from the one or more onboard vehicle sensors;

in the event that a change to the driver identity is determined to have occurred,

determining a log stop time and generating a driver log entry based at least in part on the driver identity, the log start time, and the log stop time; and

in the event that a change to the driver identity is determined to have not occurred, associating driving data with the driver identity.

18. A computer program product for determining a driver log entry, the computer program product being embodied in a tangible and non-transitory computer readable storage medium and comprising computer instructions for:

determining a log start time;

determining a drive maneuver signature associated with the driver based at least in part on data from the one or more onboard vehicle sensors, wherein the drive maneuver signature comprises measurable characteristic behaviors or a recognized manner associated with performing one or more drive maneuvers;

determining a driver identity after the log start time based at least in part on the drive maneuver signature associated with the driver;

determining whether a change to the driver identity has occurred based at least in part on data from the one or more onboard vehicle sensors;

in the event that a change to the driver identity is determined to have occurred,

determining a log stop time and generating a driver log entry based at least in part on the driver identity, the log start time, and the log stop time; and

in the event that a change to the driver identity is determined to have not occurred, associating driving data with the driver identity.
