摘要： The invention relates to a method for preventing load change impacts in a motor vehicle, especially as a result of abrupt changes in the position of the accelerator. At least one dual clutch mechanism is proved between the drive engine and the gearbox, wherein the gearbox has several selectable gear steps and the clutch is controlled in relation to the torque which is to be transmitted. The driving comfort is improved by controlling the clutch during the starting process of the motor vehicle and/or the gear steps are engaged during the starting process of the vehicle in such a way that the speed of rotation (nAW1; nAW2) of the gear input shaft is lower than the idling position speed (nLL) of rotation of the engine.

摘要： The invention relates to a twin clutch transmission (1) for a motor vehicle. This twin clutch transmission (1) has two input shafts (2, 3), two clutches (K1, K2) and at least one first and one second driving shaft (4, 5). The first input shaft (2) can be actively connected to the first clutch (K1), and the second input shaft (3) can be actively connected to the second clutch (K2). The first driving shaft (4) is situated underneath the input shafts (2, 3) and the second driving shaft (5) is situated above the input shafts (2, 3) (or reversed). The input shafts (2, 3) and driving shafts (4, 5) comprise intermeshing gear wheels, and at least two gear wheels (Z1 to Z18) form a gear step. At least one gear wheel of a gear step is provided in the form of an engageable and/or disengageable idler gear, and the other gear wheel is preferably provided in the form of a fixed gear. Each driving shaft (4, 5) has a driving gear wheel (19, 20) for transferring rotatory force to the axle drive (21). Another shaft is provided for realizing the reverse gear RG. The aim of the invention is to realize a versatile highly designed and compact transmission. To this end, the additional shaft is provided in the form of a third driving shaft (22), this third driving shaft (22) has a drive gear wheel (23) for transferring rotatory force to the axle drive (21), and the drive gear wheels (19, 20, 23) of the driving shafts (4, 5) engage with an axle drive gear (21a) of the axle drive (21).

摘要： The invention relates to a method for actuating at least two clutches (16, 18) which transmit torque in parallel in the drive train (10) of a motor vehicle (1) and are provided with different successive fixed speed transmissions (I1, I2) as gear stages (20, 22) between a drive shaft (24) and an output shaft (26). The clutches are triggered in such a way during acceleration processes and particularly during starting of the motor vehicle that both clutches (16, 18) simultaneously transmit torques and a resulting transmission of torque takes place continuously between the drive shaft (24) and the output shaft (26). According to the invention, the rotational speed (ω1) of the drive shaft (24) is greater than the respective rotational speed (ω31 or ω32) of the respective transmission input shaft of the respective partial train (12, 14) at the secondary end of the respective clutch (16, 18) during the entire starting process, or the rotational speed (ω1) of the drive shaft (24) is greater than or the same as the respective rotational speed (ω31 or ω32) of the respective transmission input shaft of the respective partial train (12, 14) at the secondary end of the respective clutch (16, 18) during an acceleration process.

摘要： The invention relates to a method for controlling an automatic gearbox having a plurality of transmission stages and pertaining to a motor vehicle driven by a drive engine, the shift from one transmission stage to another transmission stage being carried out according to the position of a power regulator and the actual speed of the vehicle. Two selectable successive transmission stages are associated with every possible driving speed inside a pre-determined speed range (A, B, C, D, E), and if the driving speed is inside the pre-determined speed range, the transmission stage with the highest transmission ratio is selected in a phase with a low power demand on the power regulator, and the transmission stage with the lowest transmission ratio is selected in a second phase with a higher power demand. This applies to at least one shifting direction (HSxy, RSxy) of the transmission stages, the ranges for upshifting (HSxy) and downshifting (RSxy) partially overlapping.
