The adaptation value memory has a predetermined number of support points which are addressable via data records of values of address operating values. A learning operation is initiated if a support point region is left during operation of the internal combustion engine and if steady state operation was present therebefore. The adaptation value of the above-mentioned support point is changed by the learning operation when a control means issues an actuating variable which deviates from a desired actuating variable. The actuating variable deviation is not applied in full strength, instead, it is applied attenuated to change the old adaptation value. This is performed by means of an attenuation means which, as main function groups, has a learning intensity table 26, a counter read memory 27 and a counter difference table 28. The counter read memory stores the number of already completed learning cases for each support point. The learning intensity table issues a learning intensity value in dependence upon counter reading and the value of the actuating variable deviation. The counter reading is then changed, that is, for small actuating variable deviations, each time by "1", so long as a maximum value has not yet been reached.
