Method for detecting a pinching situation when moving a movable component

A device for detecting a pinching situation when moving an adjustable component for closing an opening by means of an electric motor in a vehicle, comprising:

• first module unit, which is configured to operate the electric motor, to detect a pinching situation in the process and to control the electric motor as a function of the detection in order to reverse the adjustable component,
• wherein the first module unit is further configured:
• to receive a trigger threshold for at least one of a closing force, which is exerted by the electric motor on the adjustable component, and a physical variable, on which the closing force is based, with which the electric motor is operated, for at least one movement position of the adjustable component within a travel path available to it for the movement;
• to move the adjustable component into the movement position by operating the electric motor;
• to obtain at least one of:
• a current value of the closing force and the physical variable on which the current value of the closing force is based for the at least one movement position;
• to compare the current value and the trigger threshold;
• and
• to output a trigger signal which indicates the pinching situation dependent from the result of the step of comparing and with which the closing operation of the adjustable component is switched to its reversing operation;
• second module unit, which is configured:
• to read in at least one of:
• a trigger threshold and at least one of:
• a current value of the closing force and the physical variable on which the current value of the closing force is based for the at least one movement position;
• to determine a time period over which the adjustable component was held in other movement positions up to a point in time of the movement of the adjustable component into the movement position, in which the opening was continuously not closed by the adjustable component;
• to adapt, to at least one of:
• to increase the trigger threshold dependent from the determined time period, and to decrease the current value dependent from the determined time period relative to the read-in trigger threshold;
• and
• to transmit at least one of:
• the trigger threshold, which has been adapted, and the current value, which has been adapted, to the first module unit.
