Abstract
A device for detecting a change in a generator output signal of a vehicle generator includes a window comparator for comparing a signal amplitude of the generator output signal to at least one threshold value which limits a signal amplitude range, a detector for detecting a change in the generator output signal based on an output signal of the window comparator, a detection unit for detecting a signal amplitude difference between a maximum signal amplitude and a minimum signal amplitude of the generator output signal, and an adaptation unit for adapting the signal amplitude range of the window comparator, based on the signal amplitude difference, when there is the change in the generator output signal.
