Abstract
A method for ignition control is described in which the load gradient is determined. The load gradient is compared with a first specifiable dynamic threshold and the ignition control variable is additively retarded by application of an adaptable dynamic derivative action if the load gradient exceeds the first dynamic threshold. If the load gradient exceeds a second specifiable dynamic threshold and no knock occurs, then the output dynamic derivative action is reduced so that the ignition is advanced again.
