Method for checking an opening movement and/or a closing movement of a motor vehicle body system able to be actuated by an external force

A method for checking an opening movement and/or a closing movement of a motor vehicle body system able to be actuated by an external force, the method comprising:

• energizing an electric drive device of the vehicle body system such that a movement of the vehicle body system is driven from a closed position to an open position or from the open position to the closed position;
• measuring a drive current signal during energizing of the electric drive device;
• and
• checking whether predefined or predefinable current changes, which are given by current gradients and current amplitudes, occur in the drive current signal and whether the predefined or predefinable current changes exceed or undershoot a predefined or predefinable value during the opening and/or closing operation of the vehicle body system, and/or whether a predefined or predefinable current limit value is exceeded or undershot in the drive current signal during a pinching event within a predefined or predefinable path and/or time interval during the opening and/or closing operation of the vehicle body system.
