Method and device for detecting a fall of a mobile user terminal

Abstract

A method described and device to rapidly detect the accident-related removal of a mobile user terminal from a holder and to generate corresponding information which characterizes the fall or crash related to the accident. Rotation-rate sensor variables and acceleration variables of the mobile user terminal are acquired. A rotation or twisting of the mobile user terminal is detected in that the currently acquired and/or integrated rotation-rate sensor variables are compared to past values and/or threshold values. A movement of the mobile user terminal is detected on the basis of the currently acquired and/or integrated acceleration variables. A comparison with past values and/or threshold values may optionally also be carried out. The determination of an in particular accident-related crash of the vehicle and/or the fall of the mobile user terminal out of the holder then takes place due to the detected rotation and the detected movement.
