In a method for controlling a triggering element for passenger protection arrangement, a first connection is established from an energy source to the triggering element via a high-side control circuit, and a second connection is established from the at least one triggering element to ground via a low-side control circuit, and an ignition current is regulated to a predefined nominal value. The ignition current is continuously detected and compared with a predefined first threshold value, first phases being determined in which the ignition current falls below the first threshold value after reaching the nominal value, and second phases being determined in which the ignition current again reaches the nominal value after falling below the first threshold value. The control rate is increased if the number of alternations between the ignition current phases reaches a predefined second threshold value.

Method and system for controlling at least one triggering element for passenger protection means

A device and a method are described for controlling an electromagnetic user, especially a magnetic valve for influencing the fuel quantity to be injected into an internal combustion engine. At least one switching time of the user is taken into consideration in the control. The at least one switching time is ascertained starting from a current value.
