1. A method for automatically generating a documentation of a crash involving a vehicle, the method comprising:
- a processor executing instructions for receiving telematics data produced by one or more sensors associated with a telematics device at the vehicle, the sensors including at least one of an accelerometer, a speedometer, a barometer, a gyroscope, a compass, and a position sensor;
based on the telematics data, the processor executing instructions for determining a start time of the vehicle crash that is a beginning of a vehicle crash period and an end time of the vehicle crash period, the vehicle crash period including one or more impacts of the vehicle, the start time and the end time being determined based on comparisons of (a) features corresponding to values of telematics data in time segments of the telematics data with (b) predetermined thresholds for the features;
the processor executing instructions for determining, based on the telematics data, one or more metrics associated with the vehicle during the vehicle crash period; and
the processor automatically generating, based on the one or more metrics, a human-readable prose documentation of the vehicle crash comprising a narrative description of features of the vehicle crash during the vehicle crash period, the narrative description including one or more common phrases and one or more of the determined metrics, andcommunicating the narrative human-readable prose documentation to a device for presentation in an audible form or a readable form to a user.

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.

20. A vehicle telematics system for automatically generating a documentation of a vehicle crash, the system comprising:
-
a processor; and storage for instructions executable by the processor to; obtain telematics data from one or more sensors associated with a telematics device; calculate, based on the telematics data, a start time of the vehicle crash that is a beginning of a vehicle crash period and an end time of the vehicle crash period, the vehicle crash period including one or more impacts of the vehicle, the start time and the end time being determined based on comparisons of (a) features corresponding to values of telematics data in time segments of the telematics data with (b) predetermined thresholds for the features; determine, based on the telematics data, one or more metrics associated with a vehicle during the vehicle crash period; automatically provide, based on the one or more metrics, a human-readable prose documentation of the vehicle crash comprising a narrative description of features of the vehicle crash during the vehicle crash period, the narrative description including one or more common phrases and one or more of the determined metrics, and communicate the narrative human-readable prose documentation to a device for presentation in an audible form or a readable form to a user. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27)
