Claim Text:
1. A method of controlling and regulating a transmission brake in a shiftable transmission, the method comprising the steps of: during synchronization determining, with a control unit, on a basis of an actual detected rotational speed of a transmission shaft, a target rotational speed of a shaft to be synchronized, at least one of controlling and regulating the transmission brake, which is located within the shiftable transmission, with at least one of a hydraulic, a pneumatic, or an electromagnetic valve to slow rotation of the shaft to be synchronized such that the shaft to be synchronized assumes the determined target rotational speed, using the control and regulation of the transmission brake for synchronizing the shaft to be synchronized in a gearshift and also for carrying out additional drivetrain-relevant functions, and eliminating a tooth-on-tooth position of transmission components in relation to each other by applying, via the transmission brake, one of a continuous and a pulsed braking torque to a transmission shaft connected to one of the transmission components so as to slow rotation of the one of the transmission components, in relation the other of the transmission components, and adjust a relative rotational position of the one of the transmission components in relation to each other of the transmission components, the tooth-on-tooth position of the transmission components being defined as a relative rotational position of the transmission components at which positive engagement of the transmission components is prevented.
