Abstract
The disclosure relates to a mobile working machine with a control device, comprising a working arm, and methods for controlling the operating point of a working arm of a mobile working machine. According to the disclosure, the mobile working machine with the control device, comprising a working arm, has a working arm, a first end of which is hinged to a superstructure of the working machine. A tool is movably arranged on a second end of the working arm at an operating point. At least one first inclination sensor lies on the superstructure and at least one second inclination sensor lies on the working arm. In addition, at least one hydraulic cylinder is provided for changing the position of the operating point, said cylinder being hinged between the superstructure and the working arm. Furthermore, a control unit for processing signals from the at least two inclination sensors is provided to determine an operating point as a reference operating point and to ascertain a position change of the operating point by calculating a cylinder stroke on the basis of a volume flow into or out of the hydraulic cylinder.
