For at least one disturbance variable of the cylinder pressure signal, which disturbance variable occurs only during specific limited time spans as the pressure profile of an operating cycle, a filter tuned to the type of disturbance variable is fixed and is assigned to the corresponding disturbance variable time window or windows () in the operating cycle. The cylinder pressure signal () is then filtered as a function of the crankshaft angle, in that, according to the crankshaft position, a time-tuned and type-tuned filter is applied to a current disturbance variable.
