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.
Claims20
A computer-implemented method for reporting a potential vehicle crash, the method comprising:
- receiving, by at least one processor and from a storage device, telematics data produced by a plurality of sensors at a vehicle, wherein the plurality of sensors comprise a pressure sensor and a position sensor, and wherein the telematics data comprises a pressure within the vehicle produced by the pressure sensor and a position of the vehicle produced by the position sensor;
- identifying, by the at least one processor and based on the telematics data, a start time of the potential vehicle crash and an end time of the potential vehicle crash;
- processing, by the at least one processor, a portion of the telematics data produced between the start time and the end time of the potential vehicle crash to determine whether an airbag associated with the vehicle was deployed during the potential vehicle crash, including:
- computing, by the at least one processor, a first rate of altitude change based on the pressure within the vehicle produced by the pressure sensor;
- computing, by the at least one processor, a second rate of altitude change based on the position of the vehicle produced by the position sensor;
- computing, by the at least one processor, a difference between the first rate of altitude change and the second rate of altitude change;
- and
- determining, by the at least one processor, whether the airbag associated with the vehicle was deployed during the potential vehicle crash by comparing the difference with a predetermined threshold;
- generating, by the at least one processor, a report of the potential vehicle crash, the report including an indication of whether the airbag associated with the vehicle was deployed during the potential vehicle crash;
- and
- transmitting the report to a device for analysis of the potential vehicle crash or a driver of the vehicle during the potential vehicle crash.

A system, comprising:
- at least one processor;
- and
- memory storing instructions executable by the at least one processor to perform operations comprising:
- receiving telematics data produced by a plurality of sensors at a vehicle, wherein the plurality of sensors comprise a pressure sensor and a position sensor, and wherein the telematics data comprises a pressure within the vehicle produced by the pressure sensor and a position of the vehicle produced by the position sensor;
- identifying, based on the telematics data, a start time of a potential vehicle crash and an end time of the potential vehicle crash;
- processing a portion of the telematics data produced between the start time and the end time of the potential vehicle crash to determine whether an airbag associated with the vehicle was deployed during the potential vehicle crash, including:
- computing a first rate of altitude change based on the pressure within the vehicle produced by the pressure sensor;
- computing a second rate of altitude change based on the position of the vehicle produced by the position sensor;
- computing a difference between the first rate of altitude change and the second rate of altitude change;
- and
- determining whether the airbag associated with the vehicle was deployed during the potential vehicle crash by comparing the difference with a predetermined threshold;
- generating a report of the potential vehicle crash, the report including an indication of whether the airbag associated with the vehicle was deployed during the potential vehicle crash;
- and
- transmitting the report to a device for analysis of the potential vehicle crash or a driver of the vehicle during the potential vehicle crash.

- computing a first rate of altitude change based on the pressure within the vehicle produced by the pressure sensor;
- computing a second rate of altitude change based on the position of the vehicle produced by the position sensor;
- computing a difference between the first rate of altitude change and the second rate of altitude change;
- and
- determining whether the airbag associated with the vehicle was deployed during the potential vehicle crash by comparing the difference with a predetermined threshold;
- generating a report of the potential vehicle crash, the report including an indication of whether the airbag associated with the vehicle was deployed during the potential vehicle crash;
- and
- transmitting the report to a device for analysis of the potential vehicle crash or a driver of the vehicle during the potential vehicle crash.
