    摘要： A method for operating a drive train having a variable speed transmission connecting a drive unit with an output drive. The transmission has gears that can be selected by the driver and has a clutch that can be manually actuated. The torque intended by the driver is determined based on accelerator pedal actuation and the drive unit is operated on that basis. Whenever the driver disengages the clutch and changes gears, the torque intended by the driver is not used for operating the drive unit, rather the drive unit is automatically operated by a rotational speed control. In a first phase rotational speed control, a target value is automatically determined, that is independent of the current transmission input speed, and used for the rotational speed control. During a second phase, a target value which is dependent on the current transmission input speed is used for the rotational speed control.

    摘要： The invention relates to a method for overcoming tooth butt conditions (ZaZ) when engaging gears in transmissions. Sensitively adjusting the clutch to apply torque for rotating the drive shaft of the transmission in order to overcome tooth butt conditions has certain limits because of the proportion of the power required and desired for making said sensitive adjustment, potentially causing unpleasant jerking of the vehicle or a clearly audible locking noise of the involved positively connected elements and undesired mechanical stress to said elements. The method according to the invention eliminates said drawbacks by the fact that during each shifting process, regardless of the occurrence of a tooth butt condition, the clutch is brought into a position allowing minimal predetermined torque transmission to the drive shaft of the transmission, and said torque is supported on a transmission brake, which is often a standard component. Due to its substantially smaller size, the transmission brake can much more quickly and accurately adjust a desired net torque curve and torque progress on the drive shaft of the transmission when a tooth butt condition occurs and thus make it significantly easier to overcome the tooth butt condition.

    摘要： A device is proposed for reducing the drop in tractive force during the gear shift phase in an automated transmission (1), comprising an automatically actuated clutch, which comprises a rotation accumulator (8), which can be frictionally coupled via two transmission stages (4, 5), with each of which a friction clutch (6, 7) is associated, to the output shaft (3) of the transmission (1) or, in the case of a transmission having a downstream range group, if needed to the output shaft of the main transmission, wherein at every moment one of said two friction clutches (6, 7) at a time can be shifted, and wherein an upshift and a loading of the rotation accumulator can be achieved using one of the transmission stages (5), while a downshift and an energy discharge from said rotation accumulator (8) to said output shaft (3) can be achieved using said other transmission stage (4).

    摘要： Method for identifying a passive rolling moment of a motor vehicle (1), for example an undesired rolling moment with which the vehicle (1) starts moving in a direction opposite to a direction of travel in relation to a selected speed. According to the method, a mechanism detects reverse rotational directions of a secondary side (11) of an automatic starting element (4) which is connected to a transmission input shaft (12) of a variable speed transmission (3) in relation to a primary side (9) of the start-up element (4) connected to a driving shaft (10) of a drive engine (2), a transmission oil pump (16) which delivers independently of the rotational direction being associated with the variable speed transmission (3). The method and device provide a simple and inexpensive way for identifying reverse rotational directions close to the beginning of a starting process. For this purpose, the number of revolutions of the transmission input shaft (12) and the oil pressure in the variable speed transmission (3) are detected in a time-resolved manner and subjected to a correlation examination by way of which unequal rotational directions of the primary side (9) and of the secondary side (11) of the starting element (4) are detected when there is insufficient correlation and, as a result, drive-related measures are taken to counteract an identified undesired passive rolling moment. A device for carrying out the method is also disclosed.

    摘要： The invention relates to a shift control method in an automated manual transmission which is located in a drive train of a motor vehicle between a drive motor and a final drive, is provided with unsynchronised gear couplings and the input shaft of which can be connected to the drive shaft of the drive motor by means of an automatically controllable cut-out clutch. During an upshift, the target gear is synchronised when the cut-out clutch is open by the setting of a predominantly constant braking torque (M
    Br ) in a transmission brake that has a drive connection to the input shaft. To permit an acceleration of the gear-shift process without complicating the construction, as the input speed (n
    GKE ) approaches the output speed (n
    GKA ) the gear coupling of the target gear is partially closed to end the synchronisation of the cut-out clutch and is reopened at approximately the same time as the transmission brake is released.
