SELF-PROPELLED CONSTRUCTION MACHINE AND METHOD FOR CONTROLLING A SELF-PROPELLED CONSTRUCTION MACHINE
The invention relates to a self-propelled construction machine which has a drive means 5 having a left and a right crawler track 3A, 3B, in particular a slipform paver, and to a method for controlling a self-propelled construction machine, in particular a slipform paver. The construction machine comprises a machine frame 1, a working means arranged on the machine frame, a crawler track 3A on the left in the working direction A and a crawler track 3B on the right in the working direction, and a drive means 5 for driving the left crawler track at a predetermined chain speed and the right crawler track at a predetermined chain speed. In addition, the construction machine has a control unit 7 which is configured such that, on the basis of the distance a between a front reference point 9 with respect to the machine frame 1 in the working direction A and a predetermined path 8, the chain speed of the left crawler track 3A and/or the chain speed of the right crawler track 3B is predetermined such that the front reference point 9 moves on the predetermined path 8. The control unit 7 is further configured such that, during cornering, the control is corrected on the basis of the distance b between a rear reference point 10 with respect to the machine frame in the working direction and the predetermined path 8 such that the distance between the rear reference point with respect to the machine frame in the working direction and the predetermined path reduces.
