Self-propelled construction machine and method for operating a self-propelled construction machine

摘要

Self-propelled construction machine with a machine frame (2) which is carried by a chassis (1) which has wheels or crawler tracks (3, 4), a milling drum (9) arranged on the machine frame (2) for processing the soil, a drive device (17 ) to drive the wheels or chain drives (3, 4) and the milling drum (9), a lifting device (28) for adjusting the height of the milling drum (9) in relation to the surface (16) of the soil to be worked, a control and computing unit ( 21), which is configured in such a way that a certain feed rate (v) at which the construction machine moves in the field, a certain milling drum speed (n) with which the milling drum (9) rotates, and a certain height of the milling drum in relation to the Surface (16) of the soil to be processed is adjustable so that material is removed from the soil, and a variable (Δ) characteristic of the milling profile on the basis of a functional relationship between that for the milling pro Fil characteristic variable and the feed speed (v) and / or the milling drum speed (n) is determined, characterized in that the characteristic variable (Δ) for the milling profile is a correction variable for a predetermined milling depth (h), the control and computing unit (21) is configured in such a way that, instead of the specified milling depth (h), a value corrected with the correction variable is set for the milling depth.
