摘要： A method for shifting gears of an automatic transmission of a vehicle, by way of primarily form-locking shifting elements, while driving with or without utilization of a clutch depending on a decision made by a decision device which, in the presence of certain basic conditions, causes disengagement of a starting gear without disengaging the clutch, and subsequently reads in data about the size and the progression of a quantity correlating closely with the rotational speed of an output shaft of the automatic transmission and, with inclusion of this data, determines the shifting mode for engagement of the target gear.

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： 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 operating a drive train, wherein the drive train comprises a drive aggregate, a gearbox, and a starting clutch connected between the drive aggregate and the gearbox, wherein the drive train is operated when starting to roll during coasting mode and when coasting during coasting mode such that a target value for the position of the starter clutch is determined as a function of a gearbox input speed, that the target value for the position of the starter clutch is compared to a corresponding actual value, and that an adjustment parameter for adjusting the starter clutch is generated in a controller on the basis of the difference between the target value and the actual value. The target value for the position of the starter clutch for starting to roll and for coasting is determined such that, for a defined value of the gearbox input speed, a different target value is determined for the position of the starter clutch for starting to roll than for coasting.

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： 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.-

摘要： The invention concerns a method and a device for controlling an automated transmission, in which a transmission control device is provided which, on the basis of input signals, emits to suitable actuators control signals which initiate a shift sequence of the automatic transmission. To determine an optimum target gear for a shift process appropriate for the situation, it is provided that on the basis of the input signals the transmission control device first decides whether a traction force reduction of the driven wheels of the vehicle should be initiated and if the decision is positive the transmission control device emits signals which result in a defined traction force reduction of the drive wheels, the transmission control device then reads in traction force reduction data from which a change in the driving speed of the vehicle as a reaction to the traction force reduction can be derived, from the traction force reduction data it then forms a driving resistance magnitude which correlates directly with the current driving resistance of the vehicle, and finally, it takes this driving resistance magnitude into consideration when selecting the target gear.
