Self-propelled civil engineering machine and method of controlling a civil engineering machine
First Claim
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, andhaving 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, andthe 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 thatthe 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.

Abstract
A civil engineering machine and a method of controlling the machine are based on the position of at least one reference point which is relevant to the control of the civil engineering machine being changed, as the civil engineering machine moves, as a function of a relative position of the at least one reference point relative to a desired path of travel.

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.

12. A self-propelled civil engineering machine, comprising:
-
a chassis; a working unit arranged on the chassis and configured to produce structures on a piece of ground or to change the piece of ground; a drive unit configured to move the chassis and working unit in translatory and/or rotational movements on the piece of ground; at least one reference point defined on the civil engineering machine; at least one position sensor; and a controller configured to receive input signals from the at least one sensor and to send control signals to the drive unit, the controller being configured to determine a deviation of the at least one reference point from a desired path of travel and to control the drive unit depending on the deviation, so that the at least one reference point moves along the desired path of travel or at a preset spacing from the desired path of travel, the controller being 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 continuously changed depending on a position of the at least one reference point relative to the desired path of travel. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)

20. A self-propelled civil engineering machine, comprising:
-
a machine frame; a working unit arranged on the machine frame and configured to produce structures on a piece of ground or to change the piece of ground; a drive unit configured to move the machine frame and working unit on the piece of ground; at least one reference point defined on the civil engineering machine; at least two global navigation satellite system (GNSS) sensors supported from the machine frame; and a controller configured to receive input signals from the at least two GNSS sensors and to send control signals to the drive unit, the controller being configured to determine based upon the input signals from the GNSS sensors a deviation of the at least one reference point from a desired path of travel and to control the drive unit depending on the deviation, so that the at least one reference point moves along the desired path of travel or at a preset spacing from the desired path of travel, the controller being 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 depending on a position of the at least one reference point relative to the desired path of travel. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27)
