1. A method for determining an optimal route for a vehicle having a control unit having logic, an electrical drive system with an energy storage device, and a converter to charge the energy storage device, and which is operated via a fuel, the control unit being configured to perform the method comprising:
- providing a destination for the vehicle;
determining one or more possible routes from a current position of the vehicle to the destination, wherein the one or more routes is/are determined in dependence upon a geographical position of refueling stations for the fuel and electric charging stations in the region between the current position and the destination;
setting an optimal route via selecting from the determined one or more possible routes; and
implementing the optimal route via expediently operating the converter to charge the energy storage device when driving along the optimal route,wherein if the optimal route is a route that is optimized for use of a refueling station, the optimal route is implemented in such a manner that a level of intensity of use of the converter is maximized so that a fill level of fuel is as low as possible when reaching the refueling station.

17. A vehicle, comprising:
-
an electrical drive system having an energy storage device; a converter to charge the energy storage device, and which is operated via a fuel; and a control unit having logic, at least partially comprising hardware configured to; provide a destination for the vehicle; determine one or more possible routes from a current position of the vehicle to the destination, wherein the one or more routes is/are determined in dependence upon a geographical position of refueling stations for the fuel and electric charging stations in the region between the current position and the destination; set an optimal route via selecting from the determined one or more possible routes; and implement the optimal route via expediently operating the converter so as to charge the energy storage device when driving along the optimal route, wherein; if the optimal route is a route that is optimized for use of a refueling station, the optimal route is implemented in such a manner that a level of intensity of use of the converter is maximized so that a fill level of fuel is as low as possible when reaching the refueling station, and if the optimal route is a route that is optimized for use of electric charging station, the optimal route is implemented in such a manner that a level of intensity of use of an electrical drive system of the vehicle is maximized so that a state of charge of the energy storage device is as low as possible when reaching an electric charging station.

18. A method for operating a vehicle having a control unit having logic, the control unit being configured to perform the method comprising:
-
providing a destination for the vehicle; determining, from a current position of the vehicle to the destination, one or more possible routes in dependence upon a geographical position of refueling stations for fuel for the vehicle and electric charging stations for the vehicle in the region between the current position and the destination; setting an optimal route via selecting from the determined one or more possible routes; and implementing the optimal route by expediently operating a converter to charge an energy storage device of an electrical drive system of the vehicle when driving along the optimal route, wherein if the optimal route is a route that is optimized for use of an electric charging station, the optimal route is implemented in such a manner that a level of intensity of use of the electrical drive system is maximized so that a state of charge of the energy storage device is as low as possible when reaching an electric charging station.
