1. A method for determining an expected consumption value of a motor vehicle for a predetermined driving situation, comprising the steps of:
a) acquiring and storing respective actual consumption values at each occurrence of the predetermined driving situation, wherein the predetermined driving situation is characterized with reference to at least one of a speed, a driven road category, an incline of a driven roadway and a traffic condition, b) checking based on the stored consumption values whether a statistically significant database for estimating a consumption exists for the predetermined driving situation, said statistically significant database defined by a median consumption and a mean interquartile range for each speed class, b1) if yes, determining the expected median consumption and determining therefrom a driving range for the motor vehicle, b2) if no, determining an estimated value for the expected consumption for the predetermined driving situation based on stored consumption values of the motor vehicle for another driving situation at a second speed belonging to a different non-overlapping second speed class having a median consumption that is comparable to the median consumption for the first speed class, wherein the interquartile ranges for the first and second speed class overlap, substituting the expected consumption value of the motor vehicle traveling with the first speed of the first speed class with the median consumption of the second speed class, and determining, from a remaining quantity of energy of the motor vehicle and the expected consumption value of the motor vehicle, the driving range of the motor vehicle. |
