Method for determining a remaining range
First Claim
1. A method for determining a partial area of a map, which partial area describes a remaining travel range of a motor vehicle, comprising:
- determining, using a computer, the remaining travel range based on energy remaining in an energy storage system for supplying a drive acting on at least one wheel of the motor vehicle, the remaining travel range being determined with an algorithm that expands starting from a current position of the motor vehicle and adds map features while expanding; and
dividing the map into rectangular geometrical structures of equal size, wherein whenever a map feature lying in a geometrical structure is added while expanding, the geometrical structure is added to the partial area.

Abstract
A method determines a partial area of a map which is described by features, the partial area describing the remaining range of a motor vehicle. An energy-storage system supplies a drive system which acts on at least one wheel of the motor vehicle. The remaining range is determined as a function of energy stored in the energy-storage system using an algorithm which expands from a current position of the motor vehicle. The method uses divides the map into geometric, in particular rectangular, structures of equal size. Whenever, in the context of the expansion, a feature lying in a structure or corresponding to a structure is added, the structure is added to the partial area.
