Abstract

A system and method to provide navigational maintenance assistance for a vehicle includes a first step of estimating when the vehicle will require maintenance. A next step includes establishing a location and direction of travel of the vehicle. A next step includes searching a database for any service stations within a range of the vehicle and ahead of the location of the vehicle in the direction of travel of the vehicle before the vehicle becomes disabled. This step can be provided by a remote service provider. A next step includes presenting the found service stations from the searching step to a driver of the vehicle via a user interface.

Claims

1. A system to provide navigational refueling assistance for a vehicle, the system comprising:

a fuel sensor in the vehicle;

a positioning device that can determine a location and direction of travel of the vehicle;

a database of refueling stations;

a processor coupled to the fuel sensor and in communication with the positioning device and database, the processor operable to estimate a remaining-fuel range of the vehicle, establish a location and direction of travel of the vehicle, and find from the database any refueling stations within a fuel range of the vehicle and ahead of the location of the vehicle in the direction of travel of the vehicle; and

a user interface coupled to the processor, the user interface accepts information on the found refueling stations from the processor and presents the information to a driver of the vehicle.

2. The system of claim 1, wherein the processor is operable to estimate the remaining-fuel range of the vehicle using an amount of remaining fuel as indicated by the fuel sensor and a mileage rate of the vehicle.

3. The system of claim 2, wherein the processor is operable to estimate a time of fuel remaining using a speed of the vehicle.

4. The system of claim 1, wherein the user interface is operable to enter refueling preferences of the driver, and the processor is operable to filter the found refueling stations with the refueling preferences.

5. The system of claim 4, wherein the refueling preferences include a user configurable search area.

6. The system of claim 1, wherein the processor can include input on traffic conditions ahead of the vehicle on the route being traveled to estimate the remaining-fuel range of the vehicle.

7. The system of claim 1, wherein if the processor estimates that there is no remaining fuel, the processor will find those refueling stations nearest to the location of the vehicle.
