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.
Claims16
A method of controlling a drive unit of a self-propelled civil engineering machine to enable the civil engineering machine to perform translatory and/or rotational movements on the ground, in which a deviation of at least one reference point on the civil engineering machine from a desired distance or path of travel which is defined by at least one straight line and/or curve is determined, the drive unit being controlled as function of the deviation of the at least one reference point on the civil engineering machine from the desired distance or path of travel in such a way that the reference point on the civil engineering machine moves along the desired distance or path of travel or along the desired distance or path of travel at a preset spacing therefrom, the method comprising:
- changing the position of the at least one reference point relative to the civil engineering machine as a function of the position of the at least one reference point relative to the desired distance or path of travel.
A method of controlling a drive unit of a self-propelled civil engineering machine, the method comprising:
- (a) defining a defined position of at least one reference point on the civil engineering machine;
- (b) defining a desired path of travel of the at least one reference point relative to a ground surface, the desired path of travel including at least one substantially straight portion and at least one curved portion;
- (c) determining a deviation of the at least one reference point from the desired path of travel;
- (d) controlling the drive unit as a function of the deviation such that the at least one reference point on the civil engineering machine moves along the desired path of travel;
- and
- (e) changing the defined position of the at least one reference point on the civil engineering machine as a function of a relative position of the at least one reference point relative to the desired path of travel.
