Abstract

A warning system automatically alerts a vehicle operator to the fact that the next available exit should be taken for a desired or necessary service such as refueling. The system includes a source of information providing the current vehicle location as well as a source of information identifying the location of available selected service locations closest to each of the next two exits of a limited access highway. The system in a preferred embodiment includes a source of information indicating the available range of the vehicle (distance to empty or D.T.E.) and a microprocessor for calculating when the driver should take the next available exit to reach the desired service. The system further includes a suitable alarm which may be an audible alarm, a visual alarm or both to alert the vehicle operator that the next available exit should be taken.
