Method for performing journey route planning for a vehicle that comprises an energy store for storing the energy for driving the vehicle, in which a) a destination sequence for the journey route to be planned is transmitted to a computation unit that is coupled to a data memory that stores data pertaining to a route network for the vehicle, b) the computation unit calculates a route sequence that connects the destinations of the destination sequence, c) a forecast remaining amount of energy in the energy store for travelling along the route sequence is calculated, d) the forecast remaining amount of energy in the energy store of the vehicle and the stored route network and a forecast energy consumption when travelling along the route network are taken as a basis, at least for the geographical position of the vehicle given a particular destination from the destinations in the destination sequence, for ascertaining those points on the route network that can still be reached from the particular destination with the forecast remaining amount of energy given this particular destination, and e) a graphical map representation is generated for at least the destination in the destination sequence, which graphical map representation involves the geographical position of this destination and the points on the route network that can still be reached from this destination with the forecast remaining amount of energy of the vehicle given this destination being visualized, wherein the route sequence includes the geographical position of a power supply device as an intermediate destination, characterized in that for each destination in the destination sequence an area on the geographical map representation is denoted that can be reached from this destination with the forecast remaining amount of energy in the energy store of the vehicle, wherein a graphical map representation is generated for the intermediate destination, which graphical map representation involves the geographical position of this intermediate destination and the points on the route network that can still be reached before the energy store is filled at the power supply device being visualized, and further the points on the route network that can be reached after the energy store is filled at the power supply device being visualized. a) a destination sequence for the journey route to be planned is transmitted to a computation unit that is coupled to a data memory that stores data pertaining to a route network for the vehicle, b) the computation unit calculates a route sequence that connects the destinations of the destination sequence, c) a forecast remaining amount of energy in the energy store for travelling along the route sequence is calculated, d) the forecast remaining amount of energy in the energy store of the vehicle and the stored route network and a forecast energy consumption when travelling along the route network are taken as a basis, at least for the geographical position of the vehicle given a particular destination from the destinations in the destination sequence, for ascertaining those points on the route network that can still be reached from the particular destination with the forecast remaining amount of energy given this particular destination, and e) a graphical map representation is generated for at least the destination in the destination sequence, which graphical map representation involves the geographical position of this destination and the points on the route network that can still be reached from this destination with the forecast remaining amount of energy of the vehicle given this destination being visualized, wherein the route sequence includes the geographical position of a power supply device as an intermediate destination,
