The complexity of the construction machine with its working implements has reached a degree at which the driver is no longer in a position to operate the machine continuously in the most efficient way. By introducing closed control circuits the operator can partly, or in some cases entirely be relieved from the execution of certain functions of the machine. Necessarily this target can only be achieved by the application of microelectronics in connection with variable hydraulic systems. Especially the problems of the sensor systems and the requirements of the electronics under the severe operating conditions of the construction machine have to be met. By means of example already installed, systems of this kind are presented and their function are discussed and evaluated also with respect to the efficiency of their application
