Abstract
The invention relates to a method for operating a closing device (1), wherein with the aid of an electric motor (4) controlled by a control unit (7), a closing element (2) can be moved against a stop edge in a closing direction, the method comprising the following steps: detecting a pinching force on an object or on a body part between the closing element and the stop edge by integrating a measurement variable, wherein the pinching force is represented by a corresponding integrator value; signalling that a maximum permissible pinching force has been reached as a function of the integrator value; temporarily storing the integrator value after the electric motor has been stopped (4); and, when a resumption of an operation of the electric motor (4) in the closing direction is requested, starting the integration of the measurement variable beginning with the temporarily stored integrator value as a starting value.
