Abstract

The invention relates to a system for controlling an internal combustion engine (100), in particular a self-igniting internal combustion engine. A signal (U) for triggering a performance-determining final controlling element (105) is stored in a characteristics map (110) for each of a corresponding fuel quantity (QK) to be injected into the engine. The signal values stored in the characteristics map (110) are then corrected in dependence upon a predetermined relationship of a signal corresponding to the value for the fuel quantity (QK) to be injected and a signal corresponding to the value for the actually injected fuel quantity (QKI).
