1. A navigation unit for a vehicle, comprising:
- a navigation unit processor configured to;
receive or determine a current location of the vehicle and vehicle energy data indicating at least one of remaining fuel or electrical energy for the vehicle,determine a distance-to-empty value based on the vehicle energy data, anddetermine range marker data based on the distance-to-empty value, the range marker data indicating a boundary on a navigation map where the vehicle can travel to from the current location of the vehicle using the remaining fuel or electrical energy;
a memory communicatively coupled to the navigation unit processor, the memory configured to retrieve a location of an energy station within the boundary on the navigation map; and
a display communicatively coupled to the navigation unit processor, and configured to;
display the boundary on the navigation map and the energy station, anditeratively update the display of the boundary on the navigation map based on an updated current location of the vehicle and an updated distance-to-empty value.

Abstract
Devices, methods and systems are disclosed herein to describe a range marker for a navigation system. The range marker may delineate a bounded area within a navigation map that a vehicle may travel based on the amount of fuel remaining. As the fuel continues to decrease during operation of the vehicle, the range marker may become smaller and smaller indicating a shrinking range since the fuel remaining decreases, thereby allowing the driver to easily identify which gas stations may be within a range of the vehicle (based on a current vehicle fuel level) and which gas stations might not be within the range of the vehicle.

10. A navigation system for a vehicle, the navigation system comprising:
-
a vehicle electronic control unit configured to; receive or determine vehicle energy data indicating at least one of remaining fuel or electrical energy for the vehicle, and determine a distance-to-empty value based on the vehicle energy data; and a navigation unit communicatively coupled to the vehicle electronic control unit and having a display, the navigation unit configured to; receive or determine a current location of the vehicle, receive the distance-to-empty value from the vehicle electronic control unit, generate range marker data based on the distance-to-empty value, the range marker data indicating a boundary on a navigation map where the vehicle can travel to from the current location using the remaining fuel or electrical energy, determine a location of an energy station within the boundary on the navigation map, display the boundary on the navigation map and the energy station, and iteratively update the display of the boundary on the navigation map based on an updated current location of the vehicle and an updated distance-to-empty value. - View Dependent Claims (11, 12, 13, 14)

15. A computer-based method of displaying a boundary on a navigation map and one or more energy stations within the boundary on the navigation map, the method comprising:
-
receiving or determining, using a navigation unit processor, a current location of the vehicle and vehicle energy data indicating at least one of remaining fuel or electrical energy for the vehicle; determining, using the navigation unit processor, a distance-to-empty value based on the vehicle energy data; determining, using the navigation unit processor, range marker data based on the distance-to-empty value, the range marker data indicating the boundary on the navigation map where the vehicle can travel from the current location using the remaining fuel or electrical energy; retrieving, from a memory communicatively coupled to the navigation unit processor, a location of an energy station within the boundary on the navigation map; displaying, using a display communicatively coupled to the navigation unit processor, the boundary on the navigation map and the energy station; and iteratively updating, using the navigation unit processor, the display of the boundary on the navigation map and the energy station based on an updated current location of the vehicle and an updated distance-to-empty value. - View Dependent Claims (16, 17, 18, 19, 20)
