  • operating the regulator as a function of a respective operating state of the battery; and

    subjecting the regulator for the engine idle rpm to a regulating signal which depends on a charge state of the battery, whereby a reduced engine idle rpm is maintained at values lower than a maximum engine idle rpm value for as long as said charge state permits in order to reduce fuel consumption by said motor vehicle.
