Abstract: The invention relates to a system for the monitored signalling of a vehicle state, in particular for the monitored signalling of an activated, at least partially automated, driving operating state of a motor vehicle and to a method for the automatic monitoring of a vehicle state-signalling device. Specifically, the invention relates not only to the system and to the method but also to a monitoring device for carrying out the method, to a computer program which is configured to execute the method and to a vehicle state-signalling device and to a vehicle, in particular to a motor vehicle, equipped with the system. In the method, a first control signal, which is configured to change an assigned signal encoder of the vehicle state-signalling device into a deactivated state, is transferred to the vehicle state-signalling device. Testing of a current actual operating state of the signal encoder is then carried out.

Abstract: The invention relates to an input device (1) for safety-relevant functions of a motor vehicle, having a switch contact (3) with a first connection (4) and a mating contact (5) with a second connection (6). A first resistor (9) is connected between a voltage supply connection (8) and one connection (4, 6) of the switch element (2) and a second voltage supply connection (7) is connected to the other connection (4, 6) of the switch element (2).
