Abstract: The present invention relates to a method for controlling a height adjustment of a stripping plate of a ground milling machine, in particular a stripping plate of a cold milling machine, during the working process, said method comprising the following steps of detecting the striking of the stripping plate against an obstacle; automatically triggering the height adjustment unit for lifting the stripping plate from a working position, in which the stripping plate is in contact with the underlying ground to be processed, to avoid a further collision with the obstacle; and automatically triggering the height adjustment unit for lowering the stripping plate back to the working position upon overcoming the obstacle.

Abstract: A method for controlling the elevation of a retaining device of a ground milling machine as well as to a ground milling machine. Essential for the invention is that the retaining device is held in an initial position at a distance from the underlying ground and is reset from a yield position.

Abstract: An operating unit for a construction machine, wherein the operating unit is attached to the construction machine so it can be folded or lowered. The operating unit has a touch screen for displaying and inputting. The selection and/or the arrangement and/or the display size of the information panels (14,14?,14?) and the operating panels (15,15?,15?) of the touch screen occurs in a situation-dependent manner.
