Abstract: For a device for the electrical actuation of a safety-critical system, having at least two terminals, at least one switch, an operator control element, by means of which at least two operating states for the system are selectable, by means of which switching positions of the at least one switch are determined, it is proposed that at least one current direction element is provided, so that for at least one of the at least two operating states a unidirectional current flow occurs between the at least two terminals.

Abstract: The invention relates to a method and a device for the early recognition of a possible failure of an electrically controlled brake system. For this purpose, the onboard power-supply voltage provided by a vehicle battery is checked for the purpose of early recognition of a possible failure of the electrically controlled brake system, in that an electrical load is switched on by a controller assigned to this load and, with the load in the switched-on state, checking of the vehicle battery is effected by means of a further controller. The result of the checking is used for the early recognition of a possible failure of the electrically controlled brake system in that, for example, it is made available to the vehicle driver in order that the latter is able to arrange in good time for replacement of the vehicle battery. A further measure consists in the switching-off of all non-safety-relevant high current-consumers in the motor vehicle.
