A vehicle control system includes a central ECU configured to generate control signals for devices, and relay devices each disposed in a communication path between the central ECU and a corresponding device among the devices. The relay devices include a specific relay device configured to output a control signal to a specific selective device not related to driving control, braking control, and steering control of a vehicle. The specific relay device includes a sub-control unit capable of controlling the specific selective device, based on an output of at least one sensor. In response to a central control abnormality that is an abnormality related to a control signal from the central ECU, the specific relay device controls, with the sub-control unit, the specific selective device coupled to the specific relay device.

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.

An airbag control device, wherein the airbag control device generates at least one actuation signal for an actuation time as a function of at least one sensor signal, wherein the airbag control device can maintain the at least one actuation signal for a holding time, wherein the airbag control device has at least one non-volatile memory in which the generation of the at least one actuation signal can be stored, wherein the airbag control device, when the at least one actuation signal is generated, stores a status signal in the at least one non-volatile memory or in a further non-volatile memory, wherein the status signal is deleted again if the at least one actuation signal was generated for longer than a storage time. Also disclosed is a voltage network in a motor vehicle and to a method for actuating a voltage network.
