Abstract

Among other things, a documentation of a crash involving a vehicle is generated automatically. Telematics data is received that has been produced by one or more sensors associated with a telematics device at the vehicle. Based on the telematics data, a vehicle crash period is determined that begins at a start time and ends at an end time of the vehicle crash. Based on the telematics data, one or more metrics are determined associated with the vehicle during the vehicle crash period. Based on one or more metrics, a human-readable documentation of the vehicle crash is generated automatically.

Claims (80)

1. A method for documenting a state of a mobile device before a start time of a vehicle crash, the method comprising:

a processor executing instructions for receiving telematics data produced by one or more sensors at the vehicle;

the processor executing instructions for identifying, based on the telematics data, a start time of the vehicle crash;

the processor executing instructions for receiving data at the vehicle during the vehicle crash;

the processor executing instructions for determining, based on the data, a call-related state of a mobile device before the start time of the vehicle crash;

the processor automatically generating documentation of the vehicle crash, the documentation comprising an indication of the call-related state of the mobile device before the start time of the vehicle crash; and

communicating the documentation to a user device for presentation to a user.

2. The method of claim 1 in which the call-related state comprises a call in progress.

3. The method of claim 1 in which the call-related state comprises no call in progress.

4. The method of claim 1 in which the call-related state comprises a hands-free state.

5. The method of claim 1 in which the received telematics data are produced by one or more sensors in a telematics device.

6. The method of claim 5 in which the mobile device comprises the telematics device.

7. The method of claim 1 in which the one or more sensors include at least one of an accelerometer, a speedometer, a barometer, a gyroscope, a compass, or a position sensor.

8. The method of claim 7 in which the one or more sensors comprise a camera or other imaging device.

9. The method of claim 1 in which the user device is associated with at least one of an automotive safety organization, an insurance company, an emergency service, a user of the mobile device, and a user of the vehicle.

10. The method of claim 1 in which the documentation comprises a human-readable narrative description of features of the vehicle crash.

11. The method of claim 10 in which generating the human-readable documentation comprises assembling predetermined prose phrases corresponding to the features of the vehicle crash.

12. The method of claim 11 in which the prose phrases identify at least one of (a) times, (b) locations or orientations, or (c) speeds.

13. The method of claim 1 in which the processor is not at the vehicle.

14. The method of claim 1 , comprising:

determining, based on one or more metrics, a direction of a vehicle impact of the vehicle; and

generating the documentation of the vehicle crash comprising the direction of the vehicle impact.

15. A method for documenting a familiarity of a user with a road associated with a vehicle crash, the method comprising:

a processor executing instructions for receiving telematics data produced by one or more sensors at the vehicle;

the processor executing instructions for identifying, based on the telematics data, a start time of the vehicle crash;

the processor executing instructions for receiving data at the vehicle during the vehicle crash;

the processor executing instructions for determining, based on the data, a state of a mobile device before the start time of the vehicle crash;

the processor determining, based on the telematics data, a road associated with the vehicle crash;

the processor determining, based on the telematics data, a familiarity of a user of the vehicle with the road associated with the vehicle crash;

the processor automatically generating documentation of the vehicle crash, the documentation comprising an indication of the state of the mobile device before the start time of the vehicle crash and the familiarity of the user with the road; and

communicating the documentation to a user device for presentation to a user.

16. A method for documenting a yawing of a vehicle during a vehicle crash, the method comprising:

a processor executing instructions for receiving telematics data produced by one or more sensors at the vehicle;

the processor executing instructions for identifying, based on the telematics data, a start time of the vehicle crash;

the processor executing instructions for receiving data at the vehicle during the vehicle crash;

the processor executing instructions for determining, based on the data, a state of a mobile device before the start time of the vehicle crash;

the processor determining, based on the telematics data, a yaw rate of the vehicle during the vehicle crash;

the processor automatically generating documentation of the vehicle crash, the documentation comprising an indication of the state of the mobile device before the start time of the vehicle crash and a description that the vehicle was yawing during the vehicle crash based on the yaw rate exceeding a predetermined threshold; and

communicating the documentation to a user device for presentation to a user.

17. A method for documenting a human gait associated with a user of a vehicle occurring after a crash of the vehicle, the method comprising:

a processor executing instructions for receiving telematics data produced by one or more sensors at the vehicle;

the processor executing instructions for identifying, based on the telematics data, a start time of the vehicle crash;

the processor executing instructions for receiving data at the vehicle during the vehicle crash;

the processor executing instructions for determining, based on the data, a state of a mobile device before the start time of the vehicle crash;

the processor detecting, based on the telematics data, a human gait associated with a user of the vehicle, the human gait occurring after the vehicle crash;

the processor automatically generating documentation of the vehicle crash, the documentation comprising an indication of the state of the mobile device before the start time of the vehicle crash and a description that the user of the vehicle was walking after the crash based on the human gait of the user; and

communicating the documentation to a user device for presentation to a user.
