摘要： The present disclosure relates to a propulsion control system (30) for controlling a marine vessel (10) comprising at least four propulsion units (20, 22, 24, 26). The marine vessel (10) comprises a longitudinal centre line (L) and a transversal line (T). The transversal line (T) extends in a direction perpendicular to the longitudinal centre line (L) and also extends through the steering axis of the aftmost of the propulsion units. The marine vessel (10) comprises four quadrants (I, II, III, IV) defined by the longitudinal centre line (L) and the transversal line (T) wherein a first (I) and a second (II) quadrant are located on the same side of said longitudinal centre line (L). When a combined sway and yaw motion is desired, the thrust of one propulsion unit is directed towards the second (I) quadrant, and the thrust of the other propulsion units is directed towards the first (II) quadrant.

摘要： A method is provided for determining the vertical position of at least a point of a ground portion using a work machine including an implement. The work machine further includes a position determining arrangement adapted to determine at least the vertical position of the implement and a force determining arrangement adapted to determine a force applied to the implement. The method includes determining a contact force value indicative of a contact force between the ground portion and the implement using the force determining arrangement, determining whether or not the contact force value is within a predetermined contact force value range, and if it is determined that the contact force value is within the predetermined contact force value range, using the position determining arrangement for determining at least the vertical position of a portion of the implement which is in contact with the ground portion.

摘要： A method for determining a speed profile for a marine vessel. The method includes determining a travel segment along which the marine vessel is expected to travel; determining a curvature value indicative of a curvature of the travel segment; on the basis of at least the curvature value, determining a speed profile for the marine vessel along the travel segment.

摘要： A method for controlling a propulsion operation of a propulsion unit to reach a desired speed of a marine vessel. The method comprises obtaining a target speed configuration indicating the desired speed of the marine vessel, obtaining a current speed value associated with a current speed of the marine vessel, obtaining a fill level value associated with a fill level of one or more ballast tanks of the marine vessel, and controlling the propulsion operation of the propulsion unit to reach the desired speed based on the target speed configuration, the current speed value, and on the fill level value.

摘要： A control unit is provided for a work machine. The work machine includes an implement and an arrangement for determining the position and orientation of the implement. The control unit is adapted to, for at least two different orientations of the implement, perform the steps of:determining that the implement contacts a reference surface, determining the position of a reference point for the implement when the implement and the reference surface are in contact with each other, and determining the position of a point on the periphery of the implement relative to said reference point by using said reference point position.

摘要： A boat basically includes a hull, at least one propulsion unit, a heading sensor, a position sensor and a controller. The at least one propulsion unit is movably mounted to the hull, and has a propulsion axis. The heading sensor is configured to detect a heading of the boat. The position sensor is configured to detect a position of the boat. The controller is programmed to turn the at least one propulsion unit relative to the hull such that the propulsion axis moves away from a center point of the boat to correct the heading of the boat upon determining that the boat is drifting in a drift direction based on detection results of the heading sensor and the position sensor.

摘要： A control unit is provided for a working machine. The working machine includes an implement and a main body. The implement is movable relative to the main body. The working machine further includes a control entity adapted to be activated upon receipt of an action initiating signal. The control unit is adapted to identify that a human operator of the working machine actively operates the implement relative to the main body towards a reference surface until the implement contacts the reference surface, thereby identifying a human operator input signal, and upon identification of the operator input signal, issue the action initiating signal to the control entity.
