Abstract
The invention relates to a control circuit for at least one passenger protection system () in a motor vehicle, comprising a plurality of sensors for detecting a respective parameter of the motor vehicle, and an evaluation unit connected to the sensors at the input side and adapted to produce, in accordance with the measured parameters, a release signal (Enable) activating the passenger protection device in the case of an accident. The control circuit further comprises a check unit () connected to the sensors at the input side and adapted to check the mutual plausibility of the parameters measured by the sensors and to output a first disable signal (Error) for the passenger protection device in the case of an incorrect plausibility check. A logical circuit () is connected to the evaluation unit () and the check unit on the input side and to the passenger protection device on the output side and blocks activation of the passenger protection device when a first disable signal (Error) is received. At least one inducer element () is provided for simulating a malfunction of the sensors and/or of the check unit. Said inducer element simulates only a single sensor or only a part of the sensors, thereby simulating a malfunction of the remaining sensors.
