Arrangement and method for controlling at least one operation of a work machine and work machine

An arrangement configured to control at least one operation of a work machine, the work machine comprising at least one structural element, at least one pressure medium operated actuator configured to establish said at least one operation, and at least one detection device configured to determine the position of the at least one structural element of the work machine, the arrangement comprising:

• a control valve arrangement configured to control said actuator, and
• a control device configured to control said control valve arrangement,
• wherein said control device is configured to control said control valve arrangement to adjust the pressure and/or volume flow on a return line of said actuator as dependent on said position of said at least one structural element,
• wherein the control device is further configured to adjust the pressure and/or volume flow on the return line of said actuator via said control valve arrangement as dependent on the speed and/or acceleration of said at least one structural element,
• wherein the position of said at least one structural element comprises a tilt angle of said at least one structural element in the direction of at least one axis of the at least one structural element in relation to a reference direction,
• wherein the control device is configured to adjust the pressure and/or volume flow on the return line of said actuator via said control valve arrangement as dependent on a tilt angle of at least one body part of the work machine, so that the pressure and/or volume flow on the return line of said actuator is adjusted as dependent on the tilt angle caused by an inclination of a working surface of the work machine,
• wherein the at least one detection device comprises an inertial measurement unit (IMU), and
• wherein the work machine is a mobile work machine, the mobile work machine being a forwarder, a harvester, or another forest machine.
