Abstract: An automatic transmission control method in which at least one of a starting clutch, a clutch coupling and transmission elements, for selection as well as engagement and disengagement of a gear step, are determined as a function of respectively existing variables representing the driving situation as well as the driver's wishes can be activated by actuators which are controlled by a control and regulation device. The method comprising the steps of collecting and normalizing the input variable into standard input variables; weighting with weighting factors and summarizing; converting the weighted input variables into intermediate variables; selecting a specific range of values which represents a specific shifting sequence; and implementing the shifting operation.

Abstract: A method of controlling an automatic transmission in a utility vehicle in which a driving strategy is predetermined by a transmission control system. The driving strategy is adjusted as a function of a currently determined load status of the utility vehicle. Furthermore, a transmission control system for an automatic transmission of a utility vehicle, in particular a container vehicle, which comprises a transmission control unit for controlling the transmission in accordance with a predetermined driving strategy. The transmission control unit is coupled to a load recognition module for determining the current load status of the vehicle.

Abstract: A shift control method of a range group transmission with a multi-speed main transmission, which connects with a drive motor, via a clutch (K) and an input shaft. A transmission brake optionally engages the input shaft. At least a two range group is located downstream of the main transmission. A range change shift is accomplished by changing a gear of the main transmission and the range group. The shifting sequence is accelerated by: reducing motor torque and disengaging the clutch (K); disengaging a previous range group gear; synchronizing a new range group gear; disengaging a previous main transmission gear; engaging the new range group gear; synchronizing a new main transmission gear; engaging the new main transmission gear; and engaging the clutch (K) and increasing the motor torque, such that synchronization of the new gear occurs by influencing the input shaft of the main transmission.

Abstract: A method is proposed for controlling a bridging clutch in a hydrodynamic torque transmission device of a vehicle, such that with reference to a predetermined load status of the vehicle the bridging clutch is closed in a predetermined gear (x) of the transmission, and the gear (x, x1, x2) in which the bridging clutch is closed, is selected as a function of the load status of the vehicle at the time.

Abstract: A method of shift control for an automated vehicle transmission which is connected to an engine by an automated clutch. The internal combustion engine includes a controllable fuel injection such that, during a gear shift from a gear under load to a target gear, before the loaded gear is disengaged, the torque of the engine is adjusted to an idling torque by modifying the fuel injection amount and, after the target gear has been engaged, to a load torque by a converse modification of the injection amount. At the beginning of the shift, at least one operating parameter, characterizing the vehicle's current operating condition, and/or a shift parameter, characterizing the desired shift operation, is detected and evaluated to adjust the shift to the operating situation. A fuel injection amount of the engine, associated with the idling torque, is variably adapted to the vehicle's operating condition and/or the shift operation depending on the evaluation.
