Method of triggering restraint means in a motor vehicle

A control device for carrying out a method for triggering a restraint arrangement in a motor vehicle in an event of at least one of an impact and a collision with an object, comprising:

• a first arrangement configured to detect a first time characteristic of an acceleration in a form of at least one acceleration signal;
• a second arrangement configured to generate a second time characteristic of a velocity from the at least one acceleration signal;
• a third arrangement configured to determine a threshold value for the velocity as a triggering criterion;
• a fourth arrangement configured to establish an impact velocity and an instant of the impact assisted by a pre-crash sensor system before the impact;
• a fifth arrangement configured to classify an impact situation with reference to the impact velocity;
• a sixth arrangement configured to determine a triggering time window in which the second time characteristic of the velocity is generated assisted by a classification of the impact situation;
• and
• a seventh arrangement configured to establish the threshold value for the velocity from the at least one acceleration signal using the classification of the impact situation;
• wherein the seventh arrangement and the sixth arrangement operate in parallel.
