The invention is directed to the automatic determination of a quantity which represents the rpm ratio between the transmission and the wheels. For this purpose, first and second rpm values are first detected which represent the rpm of at least one wheel and the rotational speed of a transmission component. Furthermore, a driving state quantity is formed which represents the instantaneous driving state of the motor vehicle. The essence of the invention is that a pregiven driving state can be determined when the formed driving state quantity indicates an essentially steady state driving state. The determination of the rpm transmission ratio which is sought takes place in dependence upon the detected rpm values when the pregiven operating state is detected. Furthermore, the invention relates to a stepped method which, for example, ensures a rapid determination of the differential transmission ratio after a transmission control apparatus is newly built in.
