摘要
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.
