Method for smartphone-based accident detection
First Claim
1. A method for detecting a vehicular accident event with a mobile computing device located within a vehicle, the method comprising:
- receiving a first location dataset collected at a location sensor of the mobile computing device during a first time period of movement of the vehicle;
receiving a first motion dataset collected at a motion sensor of the mobile computing device during the first time period;
extracting a vehicle motion characteristic from at least one of the location dataset and the motion dataset, wherein the vehicle motion characteristic describes the movement of the vehicle within a time window of the first time period;
comparing the vehicle motion characteristic to a motion characteristic threshold;
in response to the vehicle motion characteristic exceeding the motion characteristic threshold;
retrieving an accident detection model,receiving a second location dataset collected at the location sensor of the mobile computing device during a second time period of the movement of the vehicle, wherein the second time period is after the first time period, andreceiving a second motion dataset collected at the motion sensor of the mobile computing device during the second time period;
receiving a traffic dataset describing traffic conditions proximal a vehicle location extracted from the second location dataset, wherein the traffic conditions comprise at least one of;
a traffic level, a traffic law, and accident data;
detecting the vehicular accident event with the accident detection model, the traffic dataset, and at least one of the second location dataset and the second motion dataset;
in response to detecting the vehicular accident event, automatically initiating an accident response action at the mobile computing device.

Abstract
A method and system for detecting an accident of a vehicle, the method including: receiving a movement dataset collected at least at one of a location sensor and a motion sensor arranged within the vehicle, during a time period of movement of the vehicle, extracting a set of movement features associated with at least one of a position, a velocity, and an acceleration characterizing the movement of the vehicle during the time period, detecting a vehicular accident event from processing the set of movement features with an accident detection model, and in response to detecting the vehicular accident event, automatically initiating an accident response action.
