Abstract:
A method for knock control of an internal combustion engine, comprising:performing a knock detection on cylinders of the internal combustion engine, a knock sensor signal being produced for each cylinder; retarding a moment of ignition by a specifiable value as a function of a detected knocking combustion in at least one of the cylinders; causing at least two evaluation electronics to evaluate the knock sensor signals, at least one of the cylinders being assigned to each of the at least two evaluation electronics; causing a control electronics to effect the knock detection and a specification of the moment of ignition; monitoring a functionality of the at least two evaluation electronics; and upon a detection of a malfunction of at least one of the at least two evaluation electronics, linking the at least one cylinder assigned to the at least one evaluation electronics with the malfunction to a control of at least one of the cylinders assigned to an intact one of the at least two evaluation electronics.
