1. A method comprising:
- receiving and processing accelerometer data and at least one crash related parameter to determine that a motor vehicle may have crashed;
identifying the at least one crash related parameter as being associated with the motor vehicle'"'"'s status after the identified crash;
calculating a probability of serious injury to any occupants of the motor vehicle associated with the crash based on the at least one crash related parameter; and
determining whether to initiate a call to emergency services based on the calculated probability of serious injury.

Abstract
The present application provides methods for in-vehicle emergency telematics devices and systems to automatically qualify vehicle crash events before directly placing a 3-digit emergency call from an in-vehicle TCU to a local PSAP operator. The qualification is performed in two stages. The first stage produces a qualified crash detection decision wherein a preliminary crash detection based on impact sensors is qualified by crash related non-impact sensors and vehicle telemetry data. The second stage uses an injury severity prediction algorithm to score the detected crash and produces a decision as to whether the crash warrants an emergency call to the PSAP operator.
