Abstract

The method involves determining two rotation speeds (30, 31) of a drive train of a motor vehicle. A parameter (32) is determined by an application of infinite number of measuring values of the rotation speeds within a time-slot, where the parameter is implemented as an empirical correlation coefficient. The parameter represents a measure for a functional relation of both the rotation speeds. The two rotation speeds are implemented as the rotation speeds of a gearbox input shaft and a driven axle of a motor vehicle, respectively, where the shaft is coupled with a clutch drive of the vehicle. An independent claim is also included for a method for determining driving resistance characteristic value characterizing the driving resistance of a motor vehicle.
