In a self-propelled construction machine, specifically, a road milling machine, a surface miner or a recycler, for milling a ground surface, comprising a machine frame with a longitudinal axis, comprising a chassis with wheels or tracked ground-engaging units which support the machine frame, comprising a controller for the travelling and milling operation, comprising a height-adjustable working drum, comprising a slewable transport conveyor arranged in front of or behind the working drum as seen in the direction of travel of the milling machine with a discharge end from which worked-off milling material is dischargeable onto a point of impingement on a loading surface of a means of transport, wherein the transport conveyor is slewable about, as a minimum, a first slewing axis extending essentially orthogonal to the machine frame laterally under a slewing angle, wherein the controller comprises a control system which controls, as a minimum, the slewing angle of the transport conveyor automatically in the travelling and milling operation, it is specified for the following features to be achieved: that the control system, at least as a function of a virtual trajectory for positioning the transport conveyor which is freely specifiable in a stationary coordinate system that is independent of the position and alignment of the machine frame, controls, by means of open-loop control or closed-loop control, at least the slewing angle of the transport conveyor automatically in such a fashion that a reference point of the transport conveyor always remains on the specified trajectory in the case of a change in position of the machine frame within the coordinate system.
A self-propelled milling machine for milling a ground surface, comprising:
A method for controlling a self-propelled milling machine for milling a ground surface, wherein milling material worked off by a working drum in the milling operation is transported away by a transport conveyor comprising a discharge end, and is discharged from the discharge end onto a point of impingement on a loading surface of a transport vehicle, and wherein the transport conveyor can be automatically slewed at least laterally in the travelling and milling operation, the method comprising:
