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.

Gear control device and method for a gear control device

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.

Method and control device for adjusting a rotational speed of a shaft of a gear change transmission

In a control for a motor vehicle transmission having a clutch and means for establishing and/or releasing an engagement of a toothing or of jaws of the motor vehicle transmission including a control unit for actuating the clutch for transmitting a torque to a first component of the toothing, the control unit being adapted, for the purpose of releasing a tooth-on-tooth position of the toothing, to briefly provide a control signal for adjusting the clutch to a desired clutch position (K) in order to generate a torque pulse, the control unit determining a reaction of the motor vehicle transmission in response to the control signal from the control unit and adapting the desired clutch position (K) as a function of the reaction.
