摘要： A method provides for adapting shifts to be carried out in a transmission of a motor vehicle. The shifts are triggered by a transmission control unit and are is controlled and/or governed by the transmission control unit. An actual value corresponding to an acceleration of the motor vehicle is recorded by measuring instruments and is compared to a corresponding target value. On the basis of a deviation between the actual value and the target value, the carrying out of the subsequent shifts of the transmission control unit is adapted. The actual value corresponding to an acceleration of the motor vehicle is individually recorded for several consecutive shift stages of each shift, whereas the actual value in the individual shift stages is compared to the target value in the individual shift stages of the transmission control unit. On the basis of a deviation in the individual shift stages between the actual value and the target value, the carrying out of the subsequent shifts of the transmission control unit is individually adapted for each shift stage.

摘要： The invention concerns a method for actuating a differential lock of a differential in a motor vehicle drive-train, such that when a locking command has been issued the differential lock is engaged as soon as there is essentially no rotational speed difference at the differential lock (S8). To carry out a comfort-orientated actuation of the differential lock, when the locking command has been issued but before the differential lock is engaged, it is first checked whether there is a rotational speed difference at the differential lock (S6). If there is a rotational speed difference, this is automatically reduced before the differential lock is engaged (S7).

摘要： A method of operating a dual-clutch transmission of a vehicle having partial transmissions with respective transmission input shafts. Two friction clutches can couple a corresponding input shaft of the partial transmissions to a drive shaft. Both partial transmissions drive a common output shaft. In a process for starting the motor vehicle, a gear in each of the two partial transmissions is engaged and, if the starting speed of the vehicle in a primary direction is lower than a limit value, the gears in the two partial transmissions are kept engaged. If, however, the starting speed is higher than the limit value, the gear for the travel in an opposite direction in the partial transmission, not involved in the starting process, is disengaged and a follow-up gear, for the gear in the partial transmission involved in the starting process, is engaged.

摘要： A method for operating a dual-clutch transmission of a vehicle having partial transmissions with respective transmission input shafts. Two friction clutches can couple a corresponding input shaft of the partial transmissions to a drive shaft. Both partial transmissions drive a common output shaft. During a rocking free operation for rocking the vehicle free, a gear in each respective partial transmission is engaged for driving in opposed primary and secondary directions as specified by the driver. The clutches are alternately engaged and disengaged. For rocking the vehicle free, the clutch of the partial transmission having the gear for driving in the primary direction when engaged, is engaged based on accelerator pedal actuation, and in contrast the clutch of the partial transmission having the gear for driving in the secondary direction when engaged, is automatically engaged if neither of the accelerator or brake pedals has been actuated.

摘要： A method of releasing a stuck vehicle, in which a stuck situation is recognized and a rocking-free process is initiated and continued until the rocking-free process is suppressed. The rocking-free process is suppressed either after the activation of a parking brake of the vehicle, which was inactive at the beginning of and during the rocking-free process, for a predetermined time interval, or after the registration of a limit value of a deflection of a drive pedal of the vehicle and after the limit value of the deflection of the drive pedal is maintained or exceeded for a predetermined time interval, or after a vehicle speed falls to almost zero km/h, a minimum actuation of a drive pedal of the vehicle is registered, the vehicle speed is maintained for a predetermined time interval and the minimum actuation is maintained for the predetermined time interval.

摘要： A method of controlling an automatic transmission of a vehicle in which a hold gear function is activated by a driver request and deactivated depending on a return condition. The method comprises the step of (a) determining the return condition by a change in operating state, and (b) deactivating the hold gear function if a temporary operating state, for which the hold function is requested, ends and a change takes place between one of uphill driving and downhill driving and between driving one of up and down a hill and driving on a same plane.

摘要： A method, a control unit and a computer program product for coupling an auxiliary power take-off of a motor vehicle transmission, in which, after a command to couple the auxiliary power take-off, conditions required for the coupling of the auxiliary power take-off are checked and, if the conditions are satisfied, an actuator system for coupling the auxiliary power take-off is activated. If, after the command to couple the auxiliary power take-off, the conditions for coupling the auxiliary power take-off are not fulfilled, then a control unit acts upon drive-train components in order to produce the conditions required for the coupling of the auxiliary power take-off.

摘要： A method of operating a drive-train with an automated transmission and a drive aggregate and the automated transmission provides at least two starting gears for the forward driving direction, and with a transmission-internal or transmission-external starting clutch. The method of operating the drive-train, during crawling at a crawling speed in the forward driving direction, such that for crawling in a starting gear engaged in the transmission for forward driving and with the starting clutch engaged without slip, the drive aggregate is operated in a rotational speed regulated manner so that a crawling speed is obtained, which depends on the rotational speed of the drive aggregate and the gear ratio of the starting gear engaged in the transmission. Based on actuation of an operating element of a speed regulating unit, at least one appropriate starting gear for crawling is determined and automatically engaged in the transmission.

摘要： A motor vehicle having a braking device and drive engine which can be used independently of one another for decelerating the vehicle. A method of controlling the vehicle during a thrust operation includes steps of detecting a requirement to change a currently engaged first gear in a transmission that transfers the braking force from the engine; determining a first deceleration brought about by the engine in the first gear; determining a second deceleration brought about by the engine in a second gear to be engaged; and changing the gear by disengaging a clutch that couples the engine to the transmission, the first gear is disengaged, the second gear is engaged, and the clutch is again engaged. In this case, the braking device is controlled, during the gear change, in such manner that any jerk experienced by the vehicle is below a predetermined value.
