Abstract

A method for determining an initial float angle for skid detection in rollover sensing of a rollover of a vehicle having at least one sensor system for vehicle-dynamic signals and a control unit for activating a restraining device, which divides the driving state of the vehicle into chronologically consecutive state phases, having the following method steps carried out continuously in the first state phase: calculating a change in the float angle from the vehicle-dynamic signals; comparing the calculated change in the float angle with a predefinable threshold value; and determining the initial float angle on the basis of the calculated change in the float angle as a function of the threshold value for a first range of small changes in the float angle or for a second range of larger values of changes in the float angle and a device therefor.
