A method for activating a jamming protection function in an electrical closing system. The jamming protection function is designed to abort a movement of a closing part in a movement direction if it is detected that the movement of the closing part is obstructed by a jammed object by: -providing consecutively measured values of a motor variable of a motor that effect the movement of the closing part, wherein the motor variable gives an indication of a drive torque provided by the motor; -determining a gradient curve from the consecutively measured values of the motor variable, wherein the gradient curve is established using a derivative method that provides for a weighting of the individual consecutively measured values of the motor variable according to the measurement sequence thereof; -establishing a point in time for activating the jamming protection function according to the determined gradient curve. |
