Description

technical field

[0001] The invention relates to a construction machine. The invention also relates to a method for operating such a work machine. Background technique

[0002] Within the field of construction machinery, the development continues to grow to meet the various needs of the market. For example, construction machinery operates with intelligent controls to improve operations on the job site. In particular, construction machines can communicate with each other to optimize operations on the job site.

[0003] Since the construction machines communicate with each other directly (V2V communication) or indirectly via a control station, it is possible to operate the construction machines autonomously, ie without using an operator occupying a cab in the construction machine. Thus, in contrast to traditional work machines, autonomously controlled work machines do not require a cab because there is no operator physically located on the machine to control the work machine...
