Patent ID: 8825443

Claim:
A method for calculating a remaining range and/or a consumption of a motor vehicle with an energy storage system for a drive which acts on at least one wheel of the motor vehicle, comprising: calculating, using a calculation device, the remaining range and/or the consumption by using a first algorithm; calculating, using the calculation device, the remaining range and/or the consumption by using a second algorithm, the calculation by the calculation device of the remaining range and/or the consumption using the second algorithm requiring a higher computing load on the calculation device than the calculation by the calculation device of the remaining range and/or the consumption using the first algorithm, switching over between using the first algorithm and using the second algorithm as a function of energy stored in the energy storage system, wherein the first algorithm is an algorithm which is based on area segments with respectively assigned energy costs, and the second algorithm is a Dijkstra algorithm, which is based on road segments, or an algorithm which is derived from the Dijkstra algorithm, the second algorithm having energy values as a cost function.
