Patent ID: 8762016

Claim:
A method of actuating a form-locking shift element ( 6 ) of a transmission ( 2 ) to execute a gear shift from a currently engaged gear to a target gear of the transmission ( 2 ), the method comprising the steps of: determining an actuation time for the form-locking shift element ( 6 ) of the transmission ( 2 ) to be engaged during the gear shift, depending on a reaction time of assemblies participating in actuation of the form-locking shift element ( 6 ), depending on an engaging time of the form-locking shift element ( 6 ), and depending on at least one filtered signal, so that the form-locking shift element ( 6 ) is engaged within a specified rotational speed window encompassing a specified differential rotational speed; verifying whether the form-locking shift element ( 6 ) can actually be engaged within the specified rotational speed window depending on at least one unfiltered signal; and if it is determined that the form-locking shift element ( 6 ) can be engaged within the specified rotational speed window, not affecting the actuation of the form-locking shift element, but, if it is determined that the form-locking shift element ( 6 ) cannot be engaged within the specified rotational speed window, affecting the actuation of the form-locking shift element; if it is determined that the form-locking shift element ( 6 ) cannot be engaged within the specified rotational speed window and the reaction time of the assemblies participating in the actuation of the form-locking shift element ( 6 ) is not exceeded, blocking the actuation of the form-locking shift element and retaining the current gear; and if it is determined that the form-locking shift element ( 6 ) cannot be engaged within the specified rotational speed window and the reaction time of the assemblies participating in the actuation of the form-locking element ( 6 ) is exceeded, terminating the actuation of the form-locking shift element and shifting the transmission ( 2 ) into neutral.
