Crash detection and severity classification system implementing emergency assistance

摘要

A crash detection system is disclosed that utilizes a mobile computing device to detect a vehicular accident via one or more sensors integrated into the mobile computing device. The system monitors the sensor metrics measured by one or more sensors and generates an event sensor profile that may include the plurality of sensor metrics and additional status data, such as an indication of whether the mobile computing device was located within a vehicle when the event occurred. By comparing the plurality of sensor metrics to other crash sensor metrics, a determination may be made whether the event requires emergency assistance, which may be confirmed by determining whether the data included in the event sensor profile meets one or more exception conditions. If the event requires emergency assistance and an exception condition is not met, the mobile computing device may place a call to the appropriate emergency response personnel.

主权项

1. A computer-implemented method in a portable computing device for placing an emergency call when an event requiring emergency services is detected, comprising:
monitoring, by one or more processors of the portable computing device, a plurality of sensor metrics to determine an occurrence of an event; generating, by one or more processors of the portable computing device, status data indicative of whether the portable computing device is located within a vehicle during the occurrence of the event; determining, by one or more processors of the portable computing device, whether the portable computing device is located in the vehicle based upon an analysis of the status data; selectively determining, by one or more processors of the portable computing device, that the occurrence of the event requires emergency assistance at a location associated with the vehicle when (i) the plurality of sensor metrics associated with the occurrence of the event indicate that the event matches one that corresponds to a potential occurrence of a vehicle crash, and (ii) the status data indicates that the portable computing device is located within the vehicle when the event occurred to confirm that the event corresponds to a vehicle crash; and initiating, by one or more processors of the portable computing device, a call from the portable computing device to an emergency response service when it is determined that the occurrence of the event requires emergency assistance.
