Publication number: 20180299897Abstract: A route-planning system includes a digital-map and a controller. The digital-map is used to define a travel-route of a host-vehicle traveling to a destination. The digital-map identifies a plurality of fueling-stations along the travel-route. The controller is in communication with the digital-map. The controller determines a fuel-range of the host-vehicle. When an operator of the host-vehicle causes the host-vehicle to deviate from the travel-route and the fuel-range is less than a fuel-range-threshold, the controller notifies the operator of the host-vehicle of a fueling-station available to refuel the host-vehicle. The available fueling-station is based on the fuel-range and a distance to the fueling-station when the distance is less than a route-deviation-threshold. The controller then drives the host-vehicle to the fueling-station when the operator selects the fueling-station.Type: ApplicationFiled: April 18, 2017Publication date: October 18, 2018Inventors: Robert J.
