Abstract: A system and method for configuring a machine control unit of a construction machine for performing an earth-moving operation, the earth-moving operation comprising a multitude of phases that are to be performed consecutively, the method comprising, by a computing unit: receiving three-dimensional measuring data of a terrain in a surrounding of the construction machine in at least a first detection range, detecting elements of a previous phase of the earth-moving operation based on the three-dimensional measuring data, and configuring, based at least on the detected elements, the machine control unit to at least partially perform the next phase of the earth-moving operation automatically.

Abstract: An improved controlling of a dumping of a load of an earth moving machine, which has a conveying container configured for carrying the load. Control data for maneuvering the conveying container according to a selected dumping mode are generated by analyzing perception data and/or machine sensing data to determine a material parameter providing information on an adhesive property of a current load of the conveying container. Based on the material parameter, an appropriate dumping mode is selected, e.g. to improve efficiency of the unloading sequence and to reduce wear of the earth moving machine.

Abstract: A system for determining a swing boom angle of an excavator including a vehicle frame including a cabin, a swing boom arranged on the vehicle frame and configured to be rotated relative to the vehicle frame about a first rotation axis and a pneumatic or hydraulic cylinder. A first end of the pneumatic or hydraulic cylinder is coupled to the vehicle frame and a second end is coupled to the swing boom, wherein the cylinder is configured to be rotated relative to the vehicle frame about a second rotation axis at the first end, wherein the cylinder is configured to rotate the swing boom. The system comprises a first inertial measurement unit (IMU), configured to be mounted on the swing boom and to generate first IMU data, a second IMU configured to be mounted on the cylinder and to generate second IMU data and a processing unit.

Abstract: A system for determining a swing boom angle of an excavator. The system comprises a first measuring sensor configured to be mounted on a vehicle frame or a swing boom 4, wherein the first measuring sensor is configured to determine a first interim swing boom angle of the swing boom relative to the vehicle frame. The first interim swing boom angle is one of a discrete amount of one or more intermittent first interim swing boom angles, each of the discrete amount of one or more intermittent first interim swing boom angles being spaced from each other by at least a value of one degree. A second measuring sensor mounted on the swing boom to determine a second interim swing boom angle of the swing boom relative to the vehicle frame, the second interim swing boom angle being from an indiscrete angle range and a processing unit.

Abstract: A system for determining a swing boom angle of an excavator. The excavator comprises a lower part, an upper part comprising a cabin, the upper part being arranged on the lower part and configured to be rotated relative to the lower part about a first rotation axis and a swing boom arranged on the upper part and configured to be rotated relative to the upper part about a second rotation axis that an actual swing boom position defines a swing boom angle. The system comprises a first inertial measurement unit (IMU) configured to be mounted on the swing boom and to generate first IMU data, wherein the first IMU comprises at least one acceleration sensor and a processing unit. The processing unit is configured to receive the first IMU data, determine a direction of a centripetal acceleration acting on the first IMU and determine the swing boom angle.

Abstract: The result of working with an earth moving machine comprising a bucket may be determined using known dimensions of the bucket combined with determinations of the depth of cutting and the horizontal travel or accumulated length of horizontal travel. The depth of cutting is determined by using the bucket as a receptacle as well as a depth sensor.
