ABSTRACT:
In a method and an apparatus for open-loop and closed-loop control of operating characteristic quantities of an internal combustion engine, it is proposed that the anticipatory or pilot control area, which is variable by means of learning, be embodied such that in a factor characteristic field associated with a basic characteristic field, not only the particular support point but with decreasing influence outward the area surrounding it as well are changed by the carry-over of an averaged regulating factor value. Alternatively, or preferably combined therewith, the factor characteristic field is replaced by at least two correcting characteristic fields, which have larger inclusion areas, overlapping one another, for each support point, so that even in the event of fluctuations of input quantities about a border of an area, at least one of the correcting characteristic fields will be addressed.
