Abstract:
A method for regulating a knocking in an internal combustion engine, comprising the steps of:determining a knocking combustion for a calculated first base ignition angle in at least one cylinder of the internal combustion engine originating from a previous operating condition; setting a new, second base ignition angle in accordance with an existing operating condition, wherein: in order to set the second base ignition angle for a knocking regulation that is favorable to an operation, a query is performed concerning a relative size of a setpoint ignition angle and the first base ignition angle; and after the query, if the setpoint ignition angle is smaller than the first base ignition angle, performing an ignition angle retardation to set the second base ignition angle with an adjustment value that is to be set anew and that is given by a sum of a previously determined constant retardation value and an adjusted, variable retardation value.
