Automotive construction machine and method for controlling an automotive construction machine

摘要

An automotive construction machine, in particular a slipform paver or a road milling machine, has at least one front running gear and one rear running gear in the working direction. As the construction machine advances, the lifting systems of the front running gear are extended or retracted such that the machine frame remains in a predetermined orientation to the surface of the ground in the longitudinal direction. Irregularities in the ground surface are detected as the construction machine advances, and the position of the front lifting systems, predetermined by the control or regulating unit, is monitored to keep the machine frame in a predetermined orientation to the ground surface. As the construction machine advances, the control of the rear lifting systems is engaged with a time delay subject to the control of the front lifting systems. Consequently, the working system of the construction machine, in particular the concrete mold or milling drum, is adjusted to the correct height with respect to the ground surface, so that the working system does not copy the course of the ground.

主权项

1. An automotive construction machine, comprising:
a machine frame having a working direction; at least one front running gear and at least one rear running gear configured to support the machine frame from a ground surface; a working device supported from the machine frame; front and rear lifting systems connected between the machine frame and the front and rear running gears, respectively, for adjusting a height and orientation of the machine frame relative to the ground surface; and a control unit operably associated with the lifting systems, the control unit being configured such that: the front lifting system is controlled such that the machine frame remains in a predetermined orientation with respect to the ground surface in the working direction as the construction machine advances; the rear lifting system is controlled such that the working device remains at a predetermined height relative to the ground surface as the construction machine advances; and the rear lifting system is correctively controlled with a time delay in response to control of the front lifting system so that the height of the working device relative to the ground surface is corrected by the rear lifting system at least in part to compensate for unevenness of the ground surface.
