A vehicle brake system device is provided. The vehicle brake system device includes having a signal input apparatus for inputting request signals from a driver of the vehicle which includes a sensor device which gradually detects a degree of operation of a driver-operated operating element between a position which represents non-operation and a position which represents maximum operation, and generates an operating signal which represents this degree of operation. The signal input apparatus also includes an evaluation electronics system into which the sensor device operating signal is introduced for evaluation purposes. In a switched-off state of a vehicle ignition system the sensor device and/or the evaluation electronics system cyclically assume either a standby mode with reduced electrical energy consumption from an electrical energy source in comparison to an operating mode which prevails in the switched-on state of the vehicle ignition system, the reduced energy consumption is an energy consumption level insufficient to ensure operation of the sensor device and/or the evaluation electronics system for detecting and evaluating operation of the operating element as intended, or assume an energy-saving operating mode which ensures operation of the sensor device and/or of the evaluation electronics system to detect and evaluate operation of the operating element.
