Abstract (en)
A crane (2) mounted on a vehicle (4) comprising a boom, hydraulic actuators arranged to apply movements to the crane boom system in response to received driving instructions (14); a sensor system (16) configured to monitor current positions of the crane components and to generate sensor signals (18). A control interface (20) is provided arranged to receive a set of operating instructions, a crane controller (24) configured to generate driving instructions (14) and configured to estimate a pressure level of a required working pressure of the hydraulic pump (12) and a required flow level of each of the hydraulic actuators for the wanted movements of boom, and to estimate a waste contribution measure for the wanted movements boom, based on the difference between the working pressure of a hydraulic pump (12) and the estimated pressure levels and further the estimated required flow level, of each of the hydraulic actuators for the wanted movements of the crane components (6), and also to compare the estimated waste contribution measure to a predetermined level. If the estimated waste contribution measure is larger than the predetermined level, the crane controller (24) is configured to determine and generate one driving instruction (14) to reduce the estimated required flow level of at least one of the hydraulic actuators for the wanted movements of the boom.
