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