The control of a shifting component ( 1 ) of a stepped automatic transmission is designed with one frictionally engaged element ( 2 ) and one form-locking element ( 3 ). When this shifting component ( 1 ) is engaged, a transmitting capacity of the frictionally engaged element ( 2 ) is first adjusted and when a synchronous state of the form-locking element ( 3 ) exists, the form-locking element ( 3 ) is closed. When the form-locking element ( 3 ) is closed, a transmitting capacity of the frictionally engaged element ( 3 ) is reduced. In case of a demand for disengaging the shifting component ( 1 ) before opening under load, the form-locking element ( 3 ) and the transmitting capacity of the frictionally engaged element ( 2 ) is increased so that a power flow, which is conveyed via the closed form-locking element ( 3 ) of the shifting component ( 1 ), can be conveyed via the frictionally engaged element when the form-locking element ( 3 ) is open. |
