Abstract

In order to be able to reliably trigger an emergency call from a vehicle with a radio telephone (T), even in the case of a heavy crash or collision, an autonomous emergency call unit (N) is arranged in a position in the vehicle particularly well protected from damage by collision or crash. An emergency call is triggered, for example, by a gyro (K), provided as a crash detector, which activates the emergency call unit (N) in a mechanical manner, which then transmits an emergency call to the radio telephone (T) over a short radio path according to the bluetooth standard for example, which then further transmits the emergency call to an emergency call exchange (Z) over a radio path (F). The autonomous emergency call unit (N) is provided with a bluetooth transceiver unit (BE), a battery (BA), a gyro (K) and a GSM transceiver (GSM) which transmits an emergency call to the emergency call exchange (Z) should the radio telephone (T) be damaged or destroyed.
