Systems and methods for estimating time of arrival for vehicle navigation are described. One embodiment of a method includes determining a route for a vehicle to reach a destination from a current location determining, by the computing device, an estimated time for reaching the destination from the current location. Embodiments of the method additionally include determining, by the computing device, a current range of the vehicle, based on current fuel level and vehicle fuel efficiency and determining, by the computing device and based on the current range, whether the vehicle can reach the destination without refueling. Some embodiments include revising, by the computing device, the estimated time for reaching the destination to include a waypoint to refuel in response to determining that the vehicle cannot reach the destination without refueling and providing, by the computing device, the estimated time for reaching the destination for display to a user. |

1. A method for estimating time of arrival for vehicle navigation comprising:
determining, by a computing device, a route for a vehicle to reach a destination from a current location; determining, by the computing device, an estimated time for reaching the destination from the current location; determining, by the computing device, a current range of the vehicle, based on a current fuel level and a vehicle fuel efficiency; determining, by the computing device, based on the current range, and after the vehicle has traveled a portion of the planned route, whether the vehicle can reach the destination without refueling; in response to determining that the vehicle cannot reach the destination without refueling, revising, by the computing device, the estimated time for reaching the destination to include a waypoint to refuel, wherein revising the estimated time includes calculating a time that the vehicle will be stopped at the waypoint; and providing, by the computing device, the estimated time for reaching the destination for display to a user. |
