ABSTRACT:
A device for generating a synthetic signal for testing knock control functions in engine control devices of motor vehicles has a basic noise signal generating unit, a knock signal generating unit, and an actuating device. The output signals of the basic noise and knock signal generating units can be superimposed to form a total signal. The actuating device changes the amplitude and/or frequency or the amplitude and/or frequency curve of the basic noise signal, knock signal, and/or total signal.
