  • Patent number: 7487025
    Abstract: An automatic gearshifting process and/or disengagement process of a coupling-dependent power take off for a vehicle with the power take off engaged and when the vehicle is in motion. The power tapping at the power take off is minimized before a gearshift and/or disengagement of the claw clutch of the power take off takes place. One advantage is that gearshifting can be realized with engaged coupling-dependent power take off. Comfort is increased and coupling teeth wear is minimized, whilst, at the same time, a gear and the claw clutch of the power take off are able to be securely disengaged.
