    摘要： A multi-line supply unit for a vehicle control unit, including at least two supply lines each connected to a vehicle voltage source at the input and brought together at a common node at the output; and a protective device, including, in each of the supply lines, at least one first damping diode looped into the supply lines in the forward direction, between the vehicle voltage source and the node; and an operating method for such a multi-line supply unit. At least one switch element is looped into each of the supply lines, respectively, in parallel with the damping diode, respectively; an evaluation and control unit measuring and evaluating a line voltage at the inputs of the supply lines, respectively, and measuring and evaluating a reverse-polarity-protected supply voltage at the common node, and controlling the switch elements in the supply lines as a function of the evaluation, using corresponding control signals.

    摘要： A method for recognizing a usability of a control device of a safety device in a vehicle includes: applying a voltage to the control device; acquiring a voltage curve or a current curve at the control device; and recognizing a usability of the control device as a function of the acquired voltage curve or of the acquired current curve. In particular, the correct polarity of an inductive actuator having a freewheeling diode is recognized, because in the case of incorrect polarity the inductive actuator is bridged by the freewheeling diode.

    摘要： A method for maintaining an actuator for an airbag control device. The method has a step of impressing an electric current flow through the actuator using an electric voltage having a voltage value. In addition, the method has a step of ascertaining an electric measuring current through the actuator. Here, the electric measuring current through the actuator occurs on account of the impressed electric current flow through the actuator. In addition, the method has a step of executing a comparison of the electric measuring current through the actuator to a threshold value. Moreover, the method has a step of adjusting the voltage value of the electric voltage for impressing the electric current flow through the actuator as a function of the comparison.

    摘要： An energy supply unit for supplying a consumer, includes an energy store to supply electric when the consumer is decoupled from an energy supply network. The energy supply unit includes an energy supply controller having an input coupled to the energy store, via a diode, for receiving electric energy and an output for delivering electric energy, and a monitoring unit for outputting a monitoring signal, configured to set the monitoring signal to an active state when an output voltage between the output and a reference potential is lower/greater than a predefined activation threshold value, the monitoring unit configured, when an excessively low input voltage is identified between the input and reference potential of the controller, especially paired with an excessively low output voltage, the monitoring signal is switched to the inactive state when the input voltage is above a reset threshold and the output voltage is within the monitoring band.

    摘要： A system for activating a triggering element for a passenger protection unit includes: a high-side control circuit establishing a first connection from an energy source to the triggering element, a low-side control circuit establishing a second connection of the triggering element to ground, and a regulating device regulating a firing current for the triggering element). A firing mode is selected as a function of a connected triggering element. In a first firing mode, a first firing current having a first time characteristic is generated for an ohmic triggering element, and in a second firing mode, a second firing current having a second time characteristic is generated for an inductive triggering element.
