Patent ID: 6859706

Claim:
A control circuit for at least one vehicle-occupant protection system in a motor vehicle, comprising: a plurality of sensors to detect a respective parameter of the motor vehicle; an evaluation unit which is connected to the sensors at the input end to generate a triggering signal which activates the vehicle-occupant protection system based on the measured parameters when there is an accident; a check unit, which is connected to the sensors at the input end, to check a mutual plausibility of the parameters which are measured by the sensors and to output a first disable signal for the vehicle-occupant protection system when there is an errored plausibility check; and a logic circuit, which is connected at the input end to the evaluation unit and to the check unit and at the output end to the vehicle-occupant protection system for disabling activation of the vehicle-occupant protection system when the first disable signal is present, wherein to simulate a malfunction of the sensors and/or of the check unit, at least one excitation element provided which excites a single sensor or some of the sensors and simulates a malfunction of the rest of the sensors.
