Das reversible Insassenschutzmittel kann vor dem Kollisionszeitpunkt ausgelöst und dadurch in Wirkstellung gebracht werden. Hierzu werden die Fahrzustandsdaten hinsichtlich eines Zustandes Notbremsung überwacht und bei ermitteltem Zustand Notbremsung wird das Insassenschutzmittel angesteuert. Von einer Datenverarbeitungseinrichtung wird zusätzlich ein Zustand Übersteuern und ein Zustand Untersteuern ermittelt. Wenn von der Datenverarbeitungseinrichtung der Zustand Notbremsung und/oder der Zustand Übersteuern und/oder der Zustand Untersteuern erkannt wird, wird das reversible Insassenschutzmittel angesteuert.From the DE 101 21 386 C1 is a method for driving a reversible occupant protection means in a motor vehicle with a driving condition sensor and a reversible occupant protection means known. The reversible occupant protection means can be triggered before the collision time and thereby brought into operative position. For this purpose, the driving state data are monitored with regard to a state emergency braking and in the detected state emergency braking the occupant protection means is controlled. In addition, a state of oversteer and a state of understeer are determined by a data processing device. If the state of emergency braking and / or the state of oversteer and / or the state of understeer is detected by the data processing device, the reversible occupant protection means is actuated.

Speicherung der vorgegebenen Fahrzustandsdaten F, der Speichereinheit 4 als Unfalldatenspeicher. Zusätzlich kann ein Auslösezustand jedes Auslöseszenarios zur Unfallanalyse mit einer kontinuierlichen Sequenz aufgezeichnet, d. h. gespeichert werden.In this case, each individual triggering scenario triggers an occupant protection device, in particular before an ascertained collision time, serves as a condition in the form of a triggering signal for automatic continuous data recording, ie storage of the predefined driving state data F of the memory unit 4 as accident data memory. In addition, a trigger state of each trigger scenario for accident analysis can be recorded with a continuous sequence, ie stored.

Zudem ist vorgesehen, dass die automatische Speicherung der vorgegebenen Fahrzustandsdaten F über die vorgegebene Zeitdauer auch durch eine Ausgabe einer Warnmeldung, insbesondere im Fahrzeug 1, erfolgt.In addition, it is provided that the automatic storage of the predetermined driving state data F over the predetermined period of time also by an output of a warning message, especially in the vehicle 1 , he follows.
