Patent ID: 8892359

Claim:
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.
