The invention discloses a method for detecting rotational speed fluctuations of an internal combustion engine, wherein in a first step it is checked whether the actual speed of the internal combustion engine deviates from a predeterminable desired speed by more than a predeterminable amount. In a second step, it is checked whether the time distance between two successive overtravels exceeds a predeterminable period of time; and, in a third step, it is finally determined that the rotational speed of the internal combustion engine is fluctuating if this time distance is less than the predetermined period of time. The method of the invention permits the rotational speed fluctuations of an internal combustion engine to be detected reliably while at the same time requiring little storage space and little computing time when realized by means of a computer.
