SYSTEM AND METHOD FOR TESTING A CIRCUIT DEVICE FOR CONTROLLING AN AUTOMOBILE PASSENGER PROTECTION MECHANISM

摘要

A circuit device for controlling an automobile passenger protection mechanism has a parallel circuit which is supplied by an energy source (5) delivering a test current (ILADE), said parallel circuit consisting of an energy storage capacitor (1), a series circuit consisting of a ignition element (2) and a controllable driver (3). When the energy storage capacitor (1) is discharged at least to a large extent and when the driver (3) is switched to a conductive state for testing purposes, a test voltage (UPRUF) which drops out in the series circuit (2, 3) is taken up and evaluated.
