Patent ID: 7104922

Claim:
A method for control of a shifting component of a stepped automatic transmission, the shifting component ( 1 ) having at least one frictionally engaged element ( 2 ) and at least one form-locking element ( 3 ) for transmitting power from a first half of the shifting component to a second half of the shifting component, and a common actuator for controlling actuation of both the frictionally engaged element ( 2 ) and the form-locking element ( 3 ), the method comprising the steps of: adjusting a transmitting capacity of the at least one frictionally engaged element ( 2 ), upon engagement of said shifting component ( 1 ), by actuating a first function block ( 6 ) directly communicating with the frictionally engaged element ( 2 ), and the first function block ( 6 ) communicates with a second function block ( 7 ); engaging the form-locking element ( 3 ), via the second function block ( 7 ) which triggers engagement and disengagement of the form-locking element ( 3 ) only once a synchronous state for the shifting component ( 1 ) exists; reducing the transmitting capacity of the frictionally engaged element ( 2 ), once said form-locking element ( 3 ) is engaged, so that the power is transmitted from the first half of the shifting component to the second half of the shifting component solely via said form-locking element ( 3 ) and upon a demand to disengage the at least one shifting component ( 1 ), increasing the transmitting capacity of the frictionally engaged element ( 2 ) prior to disengagement of the form-locking element ( 3 ) under load so a power flow, which is conveyed via the engaged form-locking element ( 3 ) of the shifting component ( 1 ), is conveyed via the frictionally engaged element ( 2 ) when the form-locking element ( 3 ) is disengaged.
