Abstract
An operator control element in a motor vehicle generates an activation signal as a function of the activation of the operating element, and a control unit receives the activation signal and measures a signal length of the activation signal, and signals the activation if the signal length becomes greater than a predetermined debounce time. Despite possible incorrect triggering of the activation signal owing to voltage fluctuations, the debounce time is to be short. The control unit determines for this purpose an operating parameter, and on the basis of the operating parameter it is detected that a supply voltage, made available at the control unit, satisfies a predetermined instability criterion, and when the instability criterion is satisfied the control unit delays the measurement of the signal length for a predetermined blocking time.
