A control system for an agricultural utility vehicle includes a distributor linkage for applying fertilizer, plant protection agents, or seed, the distributor linkage having a center part and two lateral extension arms. The center part is arranged so that it can be moved along a vertical axis to adjust the height of the distributor linkage. At least three sensors for determining the distance between the center part and a respective extension arm to the ground are assigned to the distributor linkage, and the system includes a data processing unit such that signals from the sensors are processed as actual values to generate an actuating signal for a hydraulic device is generated for adaptation to a target distance.

Control system, agricultural utility vehicle and method for controlling an agricultural utility vehicle

A device together with an assigned working machine for decoupling vibrations between two systems () in the form of spring-mass oscillators, of which one system () is assigned to a motion machine and the other system () is assigned to an operator operating the motion machine. The other system () at least partially performs motions about a transverse axis (Q) during driving motions of the motion machine and in doing so is subject to vertical motions in the direction of a vertical axis (z) at an absolute vertical speed (v) serving as an input variable of control devices and/or regulating devices. Those devices control a damping system () of the one system () and/or the other system () to compensate for the vibrations. The respective pitch motion of the other system () is detected by at least one rotation rate sensor. The respective measured value (&#x3c9;) of the sensor, preferably amplified by only a predeterminable factor (L), results in the absolute vertical speed (v) as input variable.

Device for decoupling vibrations between two systems and the working machine

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 () 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.

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.

Regulating and/or control system, agricultural machine comprising such a system, and method for operating an agricultural machine

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.

Control device, agricultural vehicle and method for operating an agricultural vehicle

An agricultural machine for discharging liquid includes a boom, a frame to which the boom is fixed such that the boom can be rotated about an axis of rotation pointing in the direction of travel, an actuating cylinder for rotating the boom about the axis of rotation, and a measurement and control system for the actuation of the actuating cylinder, wherein the actuating cylinder is mechanically connected to the frame on one side. The actuating cylinder is mechanically connected to the boom on the other side for the direct introduction of force. The actuating cylinder is formed as a double-acting actuating cylinder having a piston, to which pressure can be applied on both sides in order to move the boom in opposite directions of rotation.
