ABSTRACT:
A system for determining an energy-optimum route for a vehicle to take between an origin and a destination includes a computer onboard the vehicle. A global positioning system (GPS) transceiver is also onboard the vehicle for receiving vehicle position data from the satellite. The computer access a database containing both topographical map information and vehicle energy consumption data, and based thereon the computer determines and displays an energy-optimum route. The computer can also display information regarding nearby refueling stations. Also, the vehicle energy consumption data can be modified as appropriate based on the operation of the vehicle, to account for the particular vehicle's actual fuel consumption characteristics.
