Abstract: Disclosed is a method for operating a multi-gear vehicle transmission having a plurality of shifting elements (A, B, C, D, E) for engaging the gears of the vehicle transmission, where, in a neutral gear an input (AN) and an output (AB) of the vehicle transmission are decoupled from one another, and where, in a driving gear the input (AN) and the output (AB) of the vehicle transmission are coupled to one another in order to propel the vehicle, by closing at least one shifting element (B). When the neutral gear is engaged, at least an actuation condition of a vehicle brake (11) and a transmission condition with elevated drag losses are detected, where, when the neutral gear is engaged, the shifting element (B) for the driving gear is vented if it is recognized that the vehicle brake (11) has been released and the transmission condition with elevated drag losses pertains.

Abstract: Disclosed is a method for operating a multi-speed vehicle transmission having a plurality of shift elements (A, B, C, D, E) for engaging the gears of the vehicle transmission. The method includes decoupling between an input (AN) and an output (AB) of the vehicle transmission in a neutral gear, and coupling the input (AN) and the output (AB) of the vehicle transmission in a drive gear for propelling the vehicle by closing at least one shift element (B). At least one transmission state is determined when the neutral gear is engaged, where a shift element (D) for a reverse gear of the vehicle transmission is closed at least partially if the transmission is in a state with increased drag losses when the neutral gear is engaged.

Abstract: A motor vehicle transmission is connected between a drive aggregate and a drive output, and includes a powershiftable main transmission group with a plurality of forward gears and at least one reversing gear. A hydrodynamic starting element is connected between the drive aggregate and the transmission. The main transmission has frictional shifting elements of which, in each gear, a first number are closed and a second number are open. The main transmission has a parking lock that, when engaged, immobilizes an output shaft of the main transmission group. A downstream range group includes at least one interlocking shifting element and can be shifted between a first range and a second range. When the motor vehicle is stationary with the drive aggregate running, to shift the downstream range group the parking lock is first engaged, and then the downstream range group is shifted into neutral from a range to be disengaged.

Abstract: A method of shifting an automatic transmission of a motor vehicle having a hydrodynamic converter (6). The method comprising the steps of detecting a presence of predetermined stopping conditions; determining that a driver of the motor vehicle intends to cause the motor vehicle to change from a driving state to a stopped state, based on the presence of one of the predetermined stopping conditions; and automatically shifting the automatic transmission (8) into a standby mode, before the driving state has concluded. The shifting into the standby mode typically occurs when a rotational speed of the hydrodynamic converter (6) decreases to less than a rotational speed (120) of a motor and the retarder apparatus (10), of the automatic transmission, is disengaged no later than a time by which shifting into the standby mode occurs.

Abstract: A method of influencing an automated transmission of a motor vehicle having a tractional resistance detection unit, the method comprising the steps of reading data, via the tractional resistance detection unit, containing at least information about a torque of a drivetrain, a rotational speed of the drive train, and an acceleration of the vehicle, determining the external tractional resistance of the vehicle based upon the read data, and influencing the shift program by at least one of activation, adaptation and variation of the shift program, on a basis one of an actual and a statistically prepared data about the external tractional resistance of the vehicle.

Abstract: The invention relates to a method for influencing an automated transmission taking into consideration the tractional resistance with which the magnitude of an external tractional resistance can be determined easily and without need of data exchange with devices outside the vehicle, the same as independently of a digitalized road map of the area in which the vehicle drives and with low construction complexity. In particular a topographical information of the area in which the vehicle drives is obtained which allows a tractional resistance detection unit, optionally in combination with additional influencing variables in relation to the external tractional resistance, to act upon the controller of an automated transmission so that by shifting the gear change points or selecting a suitable program, reduces both the fuel consumption and the pollutant and noise emissions.
