ABSTRACT:
The invention is directed to an apparatus and a method for controlling the operating characteristic quantities of an internal combustion engine, with a characteristic set up with operating quantities of the internal combustion engine for pre-control of engine variables influencing the operating characteristic quantities, and with a control arrangement, responsive to at least one engine variable, for correctively influencing the characteristic values. The values stored in the characteristic field and selected in dependence on operating characteristic quantities of the internal combustion engine are modified via the control arrangement to correctively influence the characteristic values. In addition, the characteristic values lying within the defined region of the characteristic value modified are also changed in dependence on the modification of this particular characteristic value. The fact that the modification of a characteristic region in dependence on the modification of its respective characteristic value is weighted, permits a rapid and accurate adaptation of the characteristic to the actual operating conditions of the internal combustion engine. The invention is advantageously suitable for use in various control systems contolling air-fuel metering, ignition point, charge-air pressure, exhaust-gas recirculation of idle speed, for example.
