A device for monitoring a voltage supply for a vehicle system includes a self-diagnostic function which evaluates a logic state of the comparison signal which is output by a comparison device as a function of an input signal, and checks whether a reset signal which corresponds to the output comparison signal is generatable. The self-diagnostic function recognizes a malfunction of the comparison device when the evaluated logic state of the comparison signal does not match an expected logic state. The self-diagnostic function recognizes a malfunction of the reset device when the checked logic state of the reset signal does not match an expected logic state.

A control unit for personal protection having a polarity reversal protection between an external battery voltage and an internal voltage, to prevent an energy discharge from the control unit. The control unit also has a bidirectional DC/DC converter between an energy reserve and the internal voltage, the DC/DC converter determining its direction of conversion as a function of the internal voltage. The control unit is configured so that the control unit, after a switching-off process, records at least one measured value and generates a signal as a function of this measured value which characterizes an autarchy behavior of the control unit.

摘要:
A control device for a restraining system in a motor vehicle is proposed, a safety switch, which also includes a watchdog, performing the function of a safety switch in the control device. The safety switch monitors sensor signals which are transmitted to the processor of the control device for plausibility and triggers appropriate restraining systems via a time unit for a predefined time period only when the safety switch itself detects a trigger event. On the basis of supplementary data from the sensor signals, the safety switch infers how the sensor signals are to be processed. The safety switch is designed such that it triggers the restraining systems correspondingly assigned to the sensors. When the control device is switched on, the processor performs a test of the safety switch by generating a test signal using the sensors.
