Abstract
A control unit for a restraint system in a vehicle, including an evaluation and control unit and at least one external ignition circuit interface to which a squib for activating the restraint system is connected via a go-line and a return line, the evaluation and control unit cyclically ascertaining, by measuring, an instantaneous ohmic loop resistance of the corresponding ignition circuit and comparing this with at least one stored threshold value. The evaluation and control unit determines an instantaneous temperature in the vehicle interior, close to the time for the measured value detection for ascertaining the ignition circuit loop resistance, the evaluation and control unit carrying out a temperature compensation of the ascertained ignition circuit loop resistance for the go-line and return line of the connected ignition circuit based on the instantaneous temperature in the vehicle interior, the go-line and return line being situated outside the control unit.
