Abstract
A control unit (7) for an internal combustion engine (ICE) (1) in a motor vehicle includes a control parameter computation unit 6 which provides output signals controlling the ignition instant of an ignition unit (5) and the fuel injection characteristics of the fuel injection unit 4, thereby controlling operation of the ICE. Depending on an operating parameter of the ICE (1), preferably load, the ignition angle is corrected by an ignition angle correction unit (11) by adding a correction factor, dynamically, as the load changes. The correction factor is determined, preferably, by sensing incremental changes in loading and, equally incrementally, changing the ignition angle, repetitively, as the loading changes. The method can be realized entirely by software within a known ignition angle correction unit (7).
