Abstract
A method for releasing a tooth-on-tooth position of an interlocking shift element () of a transmission () or an interlocking shift element between two transmissions, such that the tooth-on-tooth position is released by using an actuator, in particular by using a transmission brake () or a drive clutch (), and when a tooth-on-tooth position to be released is recognized, then depending on a drive-side or input-side rotational speed of the interlocking shift element (), depending on a synchronous speed of the same and as a function of the actuators () available for releasing a tooth-on-tooth position, at least one actuator is selected, by using which the drive-side or input-side speed of the interlocking shift element () is approximated to its synchronous speed.
