[0048]The present application provides a system, method and non-transitory computer readable medium that provides in-vehicle emergency telematics solutions to automatically qualify vehicle crash events before directly placing a standard 3-digit emergency call 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 non-impact sensors in addition to vehicle telemetry data that is available, for example, from the vehicles' OBDII port. The second stage uses an ISP algorithm to score the detected crash for the purpose of deciding if the crash warrants an emergency call to the PSAP operator. Although for readability this detailed description typically refers to the US “911” emergency calls, the application also applies to the EU eCall “112” emergency calls and to eCall compliant in-vehicle emergency telematics devices and systems.
