Abstract:
1. A method for operating a ground milling machine which comprises at least one height-adjustable milling roller having a milling roller axis (L) and an open-loop and/or closed-loop control, comprising controlling a tumbling movement (T, T′) of the at least one milling roller by way of the open-loop and/or closed-loop control during lowering (A) of the at least one milling roller in operation, wherein a milling depth H can be changed during milling operation by a height adjustment of the at least one milling roller so that while changing the milling depth H, a tumbling movement is applied to the at least one milling roller comprising a two-dimensional tilting movement (T) of the milling roller axis (L), wherein said two-dimensional tilting movement (T) of the milling roller axis (L) is produced by an automatically alternating actuation of axially opposite actuators for the height adjustment of the at least one milling roller, and further wherein during the alternating actuation of the actuators, a tilting angle (d) of the milling roller axis (L) and/or a tilting frequency will be controlled by way of the open-loop and/or closed-loop control.
