Claim Text:
1. A method for controlling via a system at least one triggering element for a passenger protection arrangement, comprising: establishing, via a high-side control circuit, a first connection from an energy source to the at least one triggering element; establishing, via a low-side control circuit, a second connection from the at least one triggering element to ground; and regulating, via a control system having an evaluation and control unit, an ignition current for the at least one triggering element to a predefined nominal value after activating an ignition process, wherein the ignition current is continuously detected and compared with a predefined first threshold value, first phases being determined, via the evaluation and control unit, in which the ignition current falls below the first threshold value after reaching the nominal value, and second phases being determined, via the evaluation and control unit, in which the ignition current again reaches or exceeds the nominal value after falling below the first threshold value, and the alternations between the ignition current phases being counted and a control rate being increased, via the evaluation and control unit, if the number of alternations between the ignition current phases reaches or exceeds a predefined second threshold value; wherein the system includes the high-side control circuit, the low-side control circuit, and the control system having the evaluation and control unit.
