摘要:
In a transmission control device with a control unit, to eliminate a tooth-on-tooth position in a transmission shifting unit, a transmission clutch is adjusted to a nominal clutch value. In at least one operating mode, the control unit is designed to specify a prescribed clutch value, which is independent of any intermediate clutch value setting.

In a method and control device for adjusting a rotational speed of a shaft of a gear change transmission of a motor vehicle, a torque required for the acceleration of the transmission and derived from a drive motor is transmitted by means of an automated clutch and using the torque the rotational speed of the shaft is precisely and rapidly adjusted to a range around a target rotational speed by defining a desired value for a position of the clutch on a rotational speed difference between a measured rotational speed of the shaft and a target rotational speed so that the gear can then rapidly be changed.

In a gear shift device and a method for operating a manual gearshift device of a motor vehicle including a control unit which, in a gear shift mode is adapted to resolve a recognized tooth butt condition of a gear shift device which is to be engaged positively by a starting clutch, the control unit is adapted to select a starting mode for resolving the tooth butt condition by setting a startup readiness parameter which determines a startup readiness condition as established before the tooth butt condition is resolved for initiating clutch engagement and thereby resolving the tooth butt condition and, at the same time, starting movement of the vehicle.

A motor vehicle transmission device is described. The transmission has an actuating unit, used for canceling a tooth-on-tooth position of coupling elements, wherein the actuating unit actuates a transmission brake when the tooth-on-tooth position is detected. The transmission also has a second actuating unit for actuating a disconnect clutch, the second actuating unit actuating the disconnect clutch when the tooth-on-tooth position is detected. The actuating unit for actuating the transmission brake and the second actuating unit for actuating the disconnect clutch are actuated in coordination with one another, in order to cancel the tooth-on-tooth position.

In a method for controlling, and a control device of, an automated non-synchromesh multi-speed motor vehicle transmission, wherein, upon selection of a target gear, a form-fitting connection is to be established between shift elements of the target gear, wherein, however, with a certain rotational speed difference between the shift elements which causes chattering, no engagement takes place during actuation of the shift actuator for the target gear, when, upon monitoring, a certain chattering of the shift elements is detected, and, as a result, the engagement of the target gear is aborted in order to prevent the transmission from being damaged.
