Abstract

The invention relates to a system for controlling an internal combustion engine, in particular a self-igniting internal combustion engine. First means (200) specify a first signal (MLS, US) on the basis of at least one operating parameter (QK, N). Second means (235) specify a second signal (MLI) on the basis of at least the output signal from a lambda probe (125). A third means (220) calculates a third signal on the basis of the first signal and the second signal and applies it to a final controlling element (230). Furthermore, means (515, 520, 530, 610, 235) are provided for the temporal conditioning of the first and second signal.
