Classification: B60R

Abstract:
A method of triggering a restraint arrangement in a motor vehicle in the event of at least one of an impact and a collision with an object, comprising:detecting a first time characteristic of an acceleration in a form of at least one acceleration signal; generating a second time characteristic of a velocity from the at least one acceleration signal; determining a threshold value for the velocity as a triggering criterion; establishing an impact velocity and an instant of the impact assisted by a pre-crash sensor system before the impact; classifying an impact situation with reference to the impact velocity; determining a triggering time window in which the second time characteristic of the velocity is generated assisted by a classification of the impact situation; and establishing the threshold value for the velocity from the at least one acceleration signal using the classification of the impact situation; wherein the establishing the threshold value is performed in parallel to the determining the triggering time window.
