Airbag sensor system

摘要: The aim of the invention is to generate a timely triggering instant for an effective unfolding airbag and, at same time, take relative velocity collision opponent into account as criterion. To this end, provides that two interspaced sensors which emit millimeter waves are integrated in each vehicle body door. measuring signals said generated by means multifrequency modulation method. also during signal processing operation using radar technology, obtained turned values (Vn) and distance (R) according individual echo centers object. In addition, transversal (Vq) with regard door surface detected from series-connected situation analysis module. A classification object results measured criterion subtraction both sensor measurement outcomes. can be used side motor vehicle.
