Low Fuel Warning
First Claim
Patent Images
1. A method for providing a low fuel notification to an operator of a motor vehicle, the method comprising the steps of:
- determining a current amount of fuel in the vehicle;
calculating an estimated driving range based on the current amount of fuel;
calculating a threshold estimated driving range that is less than the estimated driving range;
obtaining information on refueling stations located between the estimated driving range and the threshold driving range;
determining whether any of the refueling stations are available based on a set of predefined requirements;
generating a list of the available refueling stations; and
generating a low fuel notification and providing the vehicle operator with a list of available refueling stations.

12. A method for providing a low fuel notification to an operator of a motor vehicle, comprising the steps of:
-
calculating a distance to a destination; determining a current amount of fuel in the vehicle; calculating an estimated driving range based on the current amount of fuel; calculating a threshold estimated driving range that is less than the estimated driving range; determining whether the distance to the destination is greater than the estimated driving range; determining whether the distance to the destination is greater than the threshold estimated driving range in response to a determination that the distance to the destination is less than the estimated driving range; obtaining information on refueling stations located between the estimated driving range and the threshold estimated driving range; determining whether any of the refueling stations are available based on a set of predefined requirements; generating a list of the available refueling stations; warning the vehicle operator in response to a determination that the distance to the destination is greater than the estimated driving range; alerting the vehicle operator in response to a determination that the distance to the destination is greater than the threshold estimated driving range; and providing the list of available refueling station in conjunction with both the warning and the alert. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
