DEVICE FOR THE CONTROL OF AN ACTIVE ELEMENT OF AN OCCUPANT RETENTION SYSTEM IN A VEHICLE

摘要

In order to produce a safing concept, an extra-safing-sensor in the control unit (ECU) is foregone and the safing function from one of the available acceleration or turn-rate sensors (S 1 to S 5 ) is replaced. Furthermore a pre-stage is connected to the firing element (Z 1 , Z 2 ), before the existing firing path, which, depending upon the sensor signals as analysed by the controller unit ( 1 ), controls a safety switch (T 11 ), in series with the firing switches and the firing element.
