Self-propelled construction machine and method for controlling a self-propelled construction machine
First Claim
1. A self-propelled construction machine comprising:
- a machine frame;
front and rear wheels or travelling gears in a working direction, supporting the machine frame;
a working tool configured to work the ground in a specified working region;
one or more cameras configured to record a portion of the ground which lies in a path of the machine when the machine moves in the working direction and further in front of the working region, and to generate image signals comprising predictive object signals representing a position of objects thereon;
a signal processor connected to the one or more cameras to receive the predictive object signals, and configured to determine current object signals relating to the working region from the predictive object signals, based on a delay which is dependent on the speed of an advance of the construction machine, said current object signals comprising image signals representing the position of the objects in a portion of the ground relating to the working region; and
a display unit connected to the signal processor to receive the current object signals, wherein the portion of the ground relating to the working region is displayed on the display unit after the delay.

Abstract
The invention relates to a self-propelled construction machine, in particular a road milling machine, which possesses an undercarriage which has front and rear—in the working direction—wheels or travelling gears, a machine frame which is borne by the undercarriage, and a working means. Furthermore, the invention relates to a method for controlling a self-propelled construction machine, in particular a road milling machine. The invention is based on the detection of objects O situated in the ground at a time at which the objects O can be readily detected. The construction machine according to the invention possesses a means for generating predictive object signals which are characteristic of the position of objects which lie in a portion of the ground which lies in the working direction A in front of the working region of the working means. Furthermore, the construction machine has a signal processing means which receives the object signals, which means is configured such that during the advance of the construction machine object signals relating to the working means are obtained from the predictive object signals, these signals being characteristic of the position of the objects in a portion of the ground which relates to the working region of the working means.

12. A method for controlling a self-propelled construction machine having a working tool for working the ground in a specified working region, the method comprising:
-
recording images of a portion of the ground which lies in front of the specified working region and in a working direction; generating predictive object signals representing the position of objects in the recorded images; obtaining current object signals relating to the working region from the predictive object signals, said current object signals representing a delayed position of the objects in a portion of the ground relating to the working region; and displaying the recorded images of the portion of the ground on a display after the delay. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)
