Abstract:
1. A self-propelled civil engineering machine, having a chassis, having a working unit arranged on the chassis of the machine, the working unit configured to produce structures on a piece of ground or to change the piece of ground, having a drive unit configured to enable the civil engineering machine to perform translatory and/or rotational movements on the ground, and having a control and calculating unit, the control and calculating unit being configured to determine a deviation from a desired distance or path of travel of at least one reference point on the civil engineering machine, the desired distance or path of travel being defined by at least one straight line and/or at least one curve, and the control and calculating unit being configured to control the drive unit depending on the deviation from the desired distance or path of travel of the at least one reference point on the civil engineering machine, the reference point thus moving along the desired distance or path of travel or along the desired distance or path of travel at a preset spacing therefrom, characterised in that the control and calculating unit is configured such that, as the civil engineering machine moves, a position of the at least one reference point relative to the civil engineering machine can be changed continuously depending on a position of the at least one reference point relative to the desired distance or path of travel.
