Abstract

Die Erfindung betrifft ein Verfahren zum Sichern eines Kraftfahrzeuges (1) mit einem elektrischen Energieversorgungssystem (7) bei einem Aufprallereignis, wobei eine Aufprallerkennungsroutine durchgeführt wird und im Falle einer Erkennung eines Aufprallereignisses das elektrische Energieversorgungssystem (7) des Kraftfahrzeuges abgeschaltet wird. Dabei werden folgende Schritte durchgeführt: •Bereitstellen eines Fahrassistenzsystems (2) mit einer Umweltsensorik (3) zur Überwachung von zumindest Teilen der Umgebung des Kraftfahrzeuges, •Bereitstellen eines Fahrdynamikregelsystems (4) mit mindestens einem Beschleunigungssensor (5), •Überwachen von zumindest Teilen der Umgebung des Kraftfahrzeuges (1) mit der Umweltsensorik (3) des Fahrassistenzsystems (2) nach Objekten (6), •Prüfen, ob eine Kollisionsgefahr mit dem Objekt (6) besteht, wenn mittels der Umweltsensorik (3) ein Objekt (6) erkannt wird, •Aktivieren eines definierten Kollisionswarnzeitfensters (Δt), wenn eine Kollisionsgefahr festgestellt wurde, •Abfragen des Beschleunigungssensors (5) innerhalb des Kollisionswarnzeitfensters (Δt), •Erkennen eines Aufprallereignisses, wenn der Beschleunigungssensor (5) des Fahrdynamikregelsystems (4) eine Überschreitung des definierten Grenzwertes ausgibt.The invention relates to a method for securing a motor vehicle (1) having an electrical energy supply system (7) in the event of an impact event, wherein an impact detection routine is carried out and, in the event of detection of an impact event, the electrical energy supply system (7) of the motor vehicle is switched off. The following steps are carried out: •Providing a driver assistance system (2) with an environmental sensor system (3) for monitoring at least parts of the surroundings of the motor vehicle, •Providing a driving dynamics control system (4) with at least one acceleration sensor (5), •Monitoring at least parts of the surroundings of the motor vehicle (1) with the environmental sensor system (3) of the driver assistance system (2) for objects (6), •Checking whether there is a risk of collision with the object (6) if an object (6) is detected by the environmental sensor system (3), •Activating a defined collision warning time window (Δt) if a risk of collision has been detected, •Querying the acceleration sensor (5) within the collision warning time window (Δt), •Detecting an impact event if the acceleration sensor (5) of the driving dynamics control system (4) indicates that the defined limit value has been exceeded.
