Abstract

Disclosed is a method for operating an interlocking shifting element of a transmission of a vehicle, where the interlocking shifting element has shifting element halves which can be moved relative to one another when opening and closing the interlocking shifting element. An electric actuator is arranged to bring about the relative movement between the shifting element halves when opening and/or closing the interlocking shifting element. An electric current strength through the electric actuator is determined and, depending on the electric current strength through the electric actuator, a conclusion is reached about the shifting position of the interlocking shifting element.
