Abstract

An apparatus for triggering a restraint apparatus, arrangement(s) or structure(s) in which, with a precrash sensor system, the apparatus generates a signal as a function of which the restraint apparatus, arrangement(s) or structure(s) is/are triggered. The precrash sensor system includes a combination of an ultrasound sensor system and a microwave sensor system. The ultrasound sensor system serves to detect objects at a speed of up to 40 km/h, while the microwave sensor system is used to detect objects up to a relative speed of 200 km/h.
