Claim 0:
1. A vehicle telematics device comprising a processor and a memory storing a crash determination application, the vehicle telematics device coupled to at least one sensor having an accelerometer, wherein the processor of the vehicle telematics device, on reading the crash determination application, is directed to:
obtain sensor data from the at least one sensor installed in a vehicle, wherein the sensor data is indicative of acceleration data in a forward vector or acceleration data in a lateral vector;
calculate peak resultant data based on the sensor data, where the peak resultant data describes the acceleration of the vehicle over a first time period;
generate crash score data based on the peak resultant data and a set of crash curve data for the vehicle, where the crash score data describes the likelihood that the vehicle was involved in a crash based on the characteristics of the vehicle and the sensor data;
calculate absolute speed change data based on the sensor data;
identify a false positive non-crash event when an oscillating event is detected in the sensor data that decreases in magnitude over time and that crosses zero in the sensor data; and
provide the obtained sensor data to a remote server system when the crash score data exceeds a crash threshold and when a false positive non-crash event is not identified.
