METHOD FOR ADJUSTING A PREDEFINED TARGET CHARGE STATE OF AN ELECTRICAL ENERGY STORAGE DEVICE OF A VEHICLE

The method involves determining whether uphill or downhill driving exists according to a pre-determined decision logic. A determination is made, whether an initial-charging condition of an energy storage lies within a pre-determined charging condition range. A reference-charging condition is adjusted according to a pre-determined adjustment logic, when the up-hill driving or down hill driving exists and the initial-charging condition of the energy storage lies within a pre-determined charging condition range. An inclination of a vehicle in relation to a horizontal line is evaluated.
