Abstract

In a motor vehicle with an adjustable coupling (intermediate device) between the (crank)shaft and floor contact elements (wheels), wherein the coupling is set in trailing throttle mode in such a way that the rotational speed of the shaft is reduced, in particular is adjusted to a predefined value, in order to reduce the internal losses of the drive, in particular an internal combustion engine.
