Method for controlling a height adjustment of a stripping plate of a ground milling machine, and ground milling machine

A method to control height adjustment of a stripping plate of a ground milling machine during a milling process, the method comprising the following steps:

• a) indirectly detecting a collision of the stripping plate with an obstacle in a working direction from a working behavior and/or a traveling behavior of the ground milling machine with at least one sensor to detect an operating variable of the ground milling machine associated with the milling process and a control unit;
• b) automatically triggering a height adjustment unit to lift the stripping plate from a working position, in which the stripping plate is in contact with underlying ground, when the collision with the obstacle has been detected;
• and
• c) subsequently, automatically triggering the height adjustment unit to lower the stripping plate back to the working position.
