Abstract:
A device for detecting knocking and regulating an internal combustion engine, comprising at least one knocking sensor adapted to be assigned to a cylinder of the internal combustion engine and levering an electrical output signal which is a function of a combustion stage in a respective cylinder; a signal evaluation unit which receives the electrical output signal and has at least one preprocessing stage, a logical evaluation device formed as a device selected from the group consisting of a fuzzy logic device and at least one neuronic network, and a microprocessor making a connection within said signal evaluation unit, said preprocessing stage comprising means for extracting characteristic features from the output signal of the knocking sensor so that individual values are selected from an output signal of said signal preprocessing stage to form at least one signal vector which is fed to said neuronic network as an input vector which forms decision criteria making possible a statement regarding a presence of knocking.
