ABSTRACT:
A control unit for actuating a device for triggering a seat belt pretensioner in a vehicle when a rear-end impact occurs includes a sensor device for supplying an acceleration signal a(t) determined at least by a positive acceleration of the vehicle in a direction corresponding to the longitudinal axis thereof, an evaluation circuit for evaluating the acceleration signal a(t) as an evaluated signal and for comparing the evaluated signal with a threshold value, and generating thereby a triggering signal z(t) for the triggering device if the threshold value is exceeded by the evaluated signal y(t), the threshold value having a sign provided for the positive vehicle acceleration.
