Abstract: An open-loop or closed-loop control system for an agricultural utility vehicle includes a distributor linkage for dispensing fertilizer, plant protection agent, or seed, and has a center part and two lateral extension arms connected by joints to the center part with a plurality of linkage sections (4) which can be folded relative to one another in a transport position and folded out relative to each other in a working position. The control system also has at least one sensor and a data processing unit configured such that signals of the sensor are processed so as to generate a control signal for the hydraulic device, and the hydraulic device can be controlled in order to set damping of vibrations occurring on the distributor linkage in a direction of travel.

Abstract: A regulating and/or control system for an agricultural machine includes a distributor linkage for spreading material, such as fertilizer, plant protection products, or seeds, the distributor linkage being pivotable about at least one axis of rotation extending in the direction of travel, with at least one first sensor device for determining the inclination of the distributor linkage; and a data processing device for processing the sensor signals. The system further includes at least one second sensor device for determining the centrifugal force FF and/or the centrifugal acceleration aF acting upon the first sensor device when the machine is turning corners, where the data processing device is configured such that an inclination measurement error of the first sensor device can be corrected based on the sensor signals of the second sensor device.

Abstract: A control device for an agricultural vehicle having a spray boom assembly for spreading material, such as fertilizer, plant protection products or seeds includes a control unit and at least two pressure control valves used for controlling an inclination of the spray boom assembly and connected to the control unit. Each pressure control valve has assigned thereto a check valve and a pressure sensor, the check valve being arranged between the pressure sensor and the pressure control valve. An agricultural vehicle and a method for operating the agricultural vehicle are arranged to spread material, such as fertilizer, plant protection products or seeds.
