A method for the movement control and/or movement regulation of a spreading apparatus for spreading liquid and/or solid active agents, which spreading apparatus comprises a spreading boom with a middle part and lateral cantilever arms, the spreading boom being arranged at a self-propelled or towed vehicle and being mounted to be pivotable about a suspension point approximately parallel to a driving direction, wherein the middle part is coupled by way of at least one regulatable adjustment device to a body section or frame section and/or to a rigidly or movably mounted support section of the vehicle, wherein the adjustment device produces a largely adjustment-force-free mechanical connection in a first operating mode, in which the spreading boom is to the greatest possible extent decoupled from torques about the swivel axis through the suspension point, which torques result from vehicle movements about the longitudinal vehicle axis, and, in a second operating mode or, as the case may be, in an adjustment mode, transmits, largely independently of disturbance torques resulting from vehicle movements, a defined adjustment force and/or a defined adjustment torque between the middle part and the support section, body section, or frame section (13, 11) for the purpose of swivelling the spreading boom in relation to the support section, body, or frame. a) in which the regulatable adjustment device is coupled with at least one sensor element (54, 54a, 54b, 54c) associated with the vehicle and detecting its vehicle body movements, the output signals of which sensor element (54, 54a, 54b, 54c) are used or, as the case may be, processed for controlling the adjustment device; and b) characterized in that the regulatable adjustment device is coupled with at least one sensor element, which detects adjustment forces and adjustment movements or, as the case may be, relative movements occurring between the middle part of the spreading apparatus and the support section, body section, or frame section. wherein the middle part is coupled by way of at least one regulatable adjustment device to a body section or frame section and/or to a rigidly or movably mounted support section of the vehicle, wherein the adjustment device produces a largely adjustment-force-free mechanical connection in a first operating mode, in which the spreading boom is to the greatest possible extent decoupled from torques about the swivel axis through the suspension point, which torques result from vehicle movements about the longitudinal vehicle axis, and, in a second operating mode or, as the case may be, in an adjustment mode, transmits, largely independently of disturbance torques resulting from vehicle movements, a defined adjustment force and/or a defined adjustment torque between the middle part and the support section, body section, or frame section (13, 11) for the purpose of swivelling the spreading boom in relation to the support section, body, or frame. a) in which the regulatable adjustment device is coupled with at least one sensor element (54, 54a, 54b, 54c) associated with the vehicle and detecting its vehicle body movements, the output signals of which sensor element (54, 54a, 54b, 54c) are used or, as the case may be, processed for controlling the adjustment device; and b) characterized in that the regulatable adjustment device is coupled with at least one sensor element, which detects adjustment forces and adjustment movements or, as the case may be, relative movements occurring between the middle part of the spreading apparatus and the support section, body section, or frame section. a) in which the regulatable adjustment device is coupled with at least one sensor element (54, 54a, 54b, 54c) associated with the vehicle and detecting its vehicle body movements, the output signals of which sensor element (54, 54a, 54b, 54c) are used or, as the case may be, processed for controlling the adjustment device; and b) characterized in that the regulatable adjustment device is coupled with at least one sensor element, which detects adjustment forces and adjustment movements or, as the case may be, relative movements occurring between the middle part of the spreading apparatus and the support section, body section, or frame section.
