The invention relates to a method for predicting a range change as a result of switching a vehicle function (F1 - F5) of a vehicle (2) on or off. In the method according to the invention, a value of an energy amount (Ebat) available in the vehicle is determined. In addition, a value of a first energy amount (E-1) that will presumably be consumed in a basic state for a certain distance and/or travel duration is predicted, wherein a first range value (RW-1) is predicted from the predicted value of the first energy amount (E-1) and the available energy amount (Ebat). Furthermore, a value of a second energy amount (E2) that would be consumed or saved if the vehicle function (F1 - F5) were switched on or off is predicted. An ambient temperature (T) of the vehicle (2) is sensed, wherein the prediction of at least the value of the second energy amount (E2) depends on the ambient temperature (T) of the vehicle (2). In addition, a second range value (RW2) by which the first range value (RW-1) would be increased or decreased if the vehicle function (F1 - F5) were switched on or off is predicted from the values of the available energy amount (Ebat), the first energy amount (E-1), and the second energy amount (E2). The second range value (RW2) is displayed. The invention further relates to a device (1) for predicting a range change as a result of switching a vehicle function (F1 - F5) of a vehicle (2) on or off. |
