摘要

The invention relates to a method for estimating an internal combustion engine ignition timing retard limit, during which a torque for actuating the internal combustion engine (1) is output. In a method in which an ignition timing retard limit can be reliably estimated, a reference measurement, in which the energy converter during at least one combustion is ascertained, is used as the basis for a stepwise ignition timing retard adjustment, in which the converted energy is determined in each step of the ignition timing retard adjustment and a standard deviation (S) is ascertained that is compared with a threshold (SW). The ignition timing retard limit is reached when the threshold (SW) is exceeded.
