[Enhanced automatic collision notification system. First field experience].

Motor vehicle accidents are the leading cause of severe injuries. Outcome of these victims is substantially influenced by rescue time and primary trauma centre care. Nowadays, automatic crash notification systems (ACN) are available offering the major possibility of immediate initiation of the rescue chain and thereby shortening rescue time up to 50%. According to the EU commission a nationwide equipping of motor vehicles with automatic crash notification systems could save up to 2,500 lives per year. Therefore, all new vehicles should be equipped with an automatic crash notification system by 2014. BMW is the first manufacturer to install an enhanced automatic crash notification system (eACN), which could optimize the rescue triage by estimating the risk for severe injuries (MAIS3+) based on telemetric transmitted accident data.
