Methods and systems for point of impact detection

A method comprising:

• receiving a set of sensor measurements from one or more sensors of a mobile device, wherein the set of sensor measurements is associated with a collision of a vehicle;
• extracting from the set of sensor measurements, a crash feature vector that includes a set of features;
• generating one or more point-of-impact features using the crash feature vector or the set of sensor measurements;
• executing a set of classifiers using the crash feature vector and the one or more point-of-impact features, wherein each classifier of the set of classifiers is configured to generate an output that is partially indicative of a point-of-impact of the collision;
• generating, from the output of each classifier of the set of classifiers, a prediction of a point of impact of the collision of the vehicle;
• and
• transmitting an indication of the point of impact to a remote device.

A non-transitory computer-readable medium storing instructions, which when executed by one or more processors, cause the one or more processors to:

• receive a first set of sensor measurements, wherein sensor measurements of the first set of sensor measurements are received from a mobile device that includes an accelerometer sensor and a global positioning service (GPS) sensor, and wherein the sensor measurements of the first set of sensor measurements are associated with vehicle collisions;
• extract, using a pattern analysis model, a set of motifs from the first set of sensor measurements, each motif of the set of motifs corresponding to a pattern of sensor measurements that occur during a vehicle collision;
• train a machine-learning model using the set of motifs;
• collect, during a collision involving a vehicle, a second set of sensor measurements using a mobile device positioned within the vehicle;
• execute the machine-learning model using the second set of sensor measurements to predict a point of impact on the vehicle;
• and
• transmit an indication of the point of impact to a remote device.
