ABSTRACT:
Method for regulating the rotational speed of a clutch-independent power take-off. The power take-off is driven by an engine arranged in a vehicle. The engine is connected to an automatic stagegeared transmission by way of an automated vehicle clutch. At least one control unit is provided for controlling the transmission, the vehicle clutch and the engine. The control unit controls the rotational speed of the engine as a function of the position of the throttle lever and controls the transmission as a function of the position of a gear selector. The rotational speed of the engine is regulated by way of a control and the degree of engagement of the vehicle clutch is regulated by way of the throttle lever when the power take-off is engaged and a drive position is selected by way of the gear selector. The rotational speed of the engine is automatically reduced when equipment engaged to the power take-off approaches a limit position.
