A crane arranged to be mounted to a vehicle and including a crane controller. The crane controller includes a machine learning algorithm, including a neural network trained to calculate a movements of a crane components based on a received trajectory instruction. A supervisory controller is provided arranged to evaluate the calculated movements by comparing an accuracy measure to a predefined safety margin. The accuracy measure is defined by the difference between a crane tip position resulting from the calculated movements when moved from a current position, and a position of the crane tip calculated by the supervisory controller, based on the received trajectory instruction and on positions of individual joints of said crane boom system, when moved from the current position, and to generate an overruling operating instruction for a system of actuators, in response to the accuracy measure being larger than the predefined safety margin.

Crane, a vehicle, and a method of the crane

A crane includes a control interface to receive an operating instruction defining a target position, and a controller to determine movements of crane components and to generate driving instructions to be applied to a system of hydraulic actuators. The controller estimates a pressure level of a required working pressure of a hydraulic pump of each of the hydraulic actuators for the determined movements, and compares the estimated pressure levels and identifies the hydraulic actuators as a high pressure function, or as a low pressure function, based on the comparisons. The controller determines a time period during a movement from a current position to a target position, in which only the hydraulic actuators identified as a high pressure function or as a low pressure function is/are activated, and generates driving instructions for the hydraulic actuators to perform the determined movements, including activation of the determined hydraulic actuators during the time period.

Crane, and a method of a crane

A driver assistance system () for a vehicle () provided with a crane () for loading or unloading objects (), the system comprises: a control unit () configured to generate a presentation signal () to be applied to a display unit (), an object detecting device () configured to capture images of the vehicle and/or of the environment around the vehicle, and configured to generate an image data signal () comprising data representing captured images, and to apply said signal () to said control unit (). The control unit () is configured to: &#x2014;determine a three dimensional, 3D, representation of at least one object, being a part of the vehicle and/or being at least one object () in the environment around the vehicle, based upon images captured by said object detecting device (), &#x2014;determine a 3D representation of the environment around the vehicle, &#x2014;determine a predetermined alert condition measure related to said determined 3D representations, wherein if said alert condition measure fulfils at least one of a set of predetermined alert criteria, the control unit is configured initiate at least one responsive activity of a set of predetermined responsive activities.
