ABSTRACT:
In a process for controlling a closing device in a motor vehicle driven by an electric motor, in particular for controlling a motor vehicle sunroof, to protect a body part from being crushed during a closing motion, a closing resistance variable is detected. The closing resistance variable is characteristic of a force counteracting the closing motion, and is used to determine whether a crush situation exists. For this purpose, an additional auxiliary variable indicative of wind load forces at a certain speed is used. If a crush situation exists, a protective measure is initiated.
