Abstract: A method and device are described for controlling an element of a drive train, which is influenceable by an operating device, in a vehicle having a control unit and a storage device, the element and/or the operating device being implementable in different variants. In this case, at least one identifier is stored in the storage device, the identifier representing the respective variant of the element and/or of the operating element which is contained in the vehicle. The element is controlled by the control unit as a function of the respective identifier in accordance with the respective variant. At the same time, different states of the respective variant of the element are selected, in particular through the operating means, an identifier being assigned for each possible state.

Abstract: The invention is directed to a system for adjusting a transmission ratio in a transmission built into a motor vehicle. The system includes at least two transmission ratio criteria with which first transmission ratios are determined based on at least two different determining modes. The system also includes a first arrangement with the aid of which a second transmission ratio is selected in accordance with a pregiven prioritization from the determined first transmission ratios. The transmission ratio is then adjusted in dependence upon the selected second transmission ratio. In an advantageous configuration of the invention, a second arrangement is provided with which the second transmission ratio is modified in accordance with a pregiven strategy. The transmission ratio is then adjusted in dependence upon the modified second transmission ratio.

Abstract: A system for adjusting a transmission ratio in a transmission built into a motor vehicle has at least two determination elements for determining values based on different determination modes with these values representing individual driving situations of the motor vehicle. An administrator calls up the values from the determination elements and stores the values. The administrator outputs individual ones of the values in response to a command whereupon the transmission ratio is adjusted at least in dependence upon the outputted ones of the values.

Abstract: The invention proceeds from a motor vehicle having a drive train and the elements of the drive train are rotatable. The determination of a quantity, which represents the traction resistance, takes place in such a manner that an acceleration quantity is detected. This acceleration quantity represents the instantaneous acceleration of the vehicle. Furthermore, a reference quantity for the acceleration of the vehicle is detected and the quantity, which represents the traction resistance, is determined in dependence upon a comparison of the detected acceleration quantity with the determined reference quantity. The essence of the invention is that a rotation quantity is determined which represents the rotation torque of at least one element mounted in the drive train. The determination of the reference quantity takes place in accordance with the invention in dependence upon the determined rotation quantity.

Abstract: The invention proceeds from a system for considering differing amounts of components for determining at least one control quantity such as for controlling the operation of a motor vehicle. Such a system is known from the state of the art wherein a value is determined as a control quantity for the adaptive transmission control. This value characterizes the type of driver or the driving style. At least two different supply objects (for example, start-up evaluation, gradient evaluation) are provided with the aid of which, for each case, a component for determining the control quantity is determined. The determined components are then supplied to at least one collector which forms the evaluation quantity, for example, by maximum formation, weighted and/or moving-window sum formation of the individually determined components. The essence of the invention is that means are provided with which the supply of the components of the supply objects is controlled to the collector.

Abstract: The invention is directed to a method and an arrangement for controlling an output torque of a drive train of a motor vehicle. A desired value for the output torque is made available by the adjustment of a transmission and by the control of the engine. The desired value is determined on the basis of a driver command signal as well as on the basis of a minimum and/or maximum output torque dependent upon operating variables.

Abstract: The invention is based on an adaptive transmission control wherein changes in the gear ratio of the automatic transmission are determined in dependence upon the detected position of the accelerator pedal actuated by the driver or variables associated therewith and in dependence upon the vehicle straight-line speed and/or the output rpm of the transmission and/or the motor rpm or variables associated therewith. Also, an adaptive variable is determined which adapts the changes of the transmission gear ratio at least to the driving situation then present. The essence of the invention is that the path data of a navigation system is used to determine the above-mentioned adaptation variable. The navigation system is a known map-supported navigation system. In this way, it is advantageously possible to precisely detect the present as well as future driving and environmental situations to which the vehicle is just then subjected or will be subjected in the near future.
