Реферат: Automatic engaging method (and disengaging method and device) for a coupling-dependent power take-off (32) when the vehicle is in motion, which is driven by an engine (1), arranged in the vehicle, via an automated disk clutch (3), an automatic stage-geared gearbox (9) in which a shaft (11) for driving the power take-off (32) is arranged. A control unit (45) controls the gearbox (9), the disk clutch (3) and the engine (1). The method is characterized in that the control unit registers that engagement of the power take-off (32) is requested; the speed of the engine (1) is controlled so that the input shaft (7) of the gearbox becomes virtually torqueless; the disk clutch (3) is disengaged and the gearbox is put in neutral position so that the intermediate shaft (11) of the gearbox is disengaged from the driving wheels of the vehicle; the intermediate shaft (11) is braked; the power take-off (32) is engaged; the control unit (45) couples the disk clutch (3) together. A torque transmitter is arranged at the power take-off (32).
