Abstract

A technique is described for determining an energy-saving route between two geographic positions on the basis of predefined cartographic data, the cartographic data describing a real traffic route network in the form of route segments and route nodes. A method aspect comprises the steps of subdividing the route segments provided for a route calculation into route segment portions that each have a predefined speed profile, providing an energy consumption value to be expected for each of the route segment portions, on the basis of the respectively assigned speed profile, and calculating weights for the respective route segments on the basis of the energy consumption values provided for the route segment portions, wherein the weights can be used to determine the energy-saving route in the context of the route calculation.
