Abstract: The prioritization method according to the present invention permits the selection of information providers independently of the selection and functioning manner of the requesting systems, for flexibilization. In a linear prioritization method according to the present invention, a list sorted by rising priority having information providers is sequentially polled, and the first information provider having a request command is selected, this request command is routed on, and the polling is ended. In an additional prioritization method according to the present invention, from a list that is not sorted, having information providers, the information provider having the maximum (minimum) request command is selected or the average request command of the requesters is ascertained. Preferably, the prioritization method according to the present invention is able to be executed using a computer system having a modular system construction.

Then, at least one counter value is changed in counter means in dependence upon the called up values. Finally, the transmission ratio is set at least in dependence upon the outputted values.

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 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.
