    摘要： 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. It is especially provided that the rotation quantities of individual elements, which are mounted in the drive train, are determined separately.

    摘要： 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. With the system of the invention, it is possible in a simple manner to adapt the number of components, which are to be considered for the formation of the evaluation quantity, to the particular situation.

    摘要： The invention proceeds from a control of a transmission which is adjustable continuously with respect to its transmission ratio, for a motor vehicle. The transmission together with a drive unit is mounted in the drive train of the motor vehicle and the drive unit has an adjustable drive torque. The transmission includes a drive end as well as an output end and operative means for establishing a mechanical operative connection between the drive end and the output end. Furthermore, detection means for detecting a slip quantity is provided. The slip quantity represents the slip between the operating means and the drive end and/or output end. Pregivable measures are initiated in response to a pregiven value of the slip quantity. The essence of the invention is that measures as follows are initiated: a drive of a clutch mounted in the drive train; and/or, a change of the transmission ratio; and/or, a change of the output torque of the drive unit. It is especially intended that measures are initiated in the sense of a slip reduction.
