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 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 method for operation of a drive train having a drive machine and an automatic, unsynchronized gearwheel variable-speed transmission, which can be connected to the drive machine by using an automatic clutch is described. A control device carries out a selection process as a function of vehicle parameters and/or operating variables of the motor vehicle to determine whether a gear change of the unsynchronized gearwheel variable-speed transmission will be carried out with the clutch engaged or disengaged. To ensure reliable operation of the motor vehicle, a gear change is carried out with the clutch disengaged in a time interval after initial starting up of the drive train and/or after starting of the drive machine and/or when a malfunction is identified in a component in the drive train.

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.
摘要:
In a method for operating a drive train having a drive motor and an automated variable speed transmission, in selected situations, such as when there is a change in the gear speed of the variable speed transmission, it is advantageous to calculate the profile of the rotational speed of the drive motor in advance. For this purpose, pre-stored profile parameters (for example in the form of gradient values when changes in rotational speed are requested) are corrected as a function of a requested difference in rotational speed. Alternatively, in addition to a corrected gradient it is possible to calculate a corrected reaction times, and to carry out the calculation in advance by means of these variables. The reaction time is obtained as a time difference between actuation of a significant change in a state variable (for example a rotational speed) of the drive train. If no previously stored values are available, changes in rotational speed can be requested and the resulting gradients and/or reaction times can be stored.

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.

摘要:
The invention starts from a transmission control device with a control unit (10) which, to eliminate a tooth-on-tooth position in a transmission shifting unit (11, 12), is designed to adjust a transmission clutch (13) to a nominal clutch value (KKick).It is proposed that in at least one operating mode the control unit (10) is designed to specify a prescribed clutch value (KDes) which is independent of any intermediate clutch value setting.
