Abstract
The energy management control system employs sensors for monitoring of energy consumption by various vehicle systems and provides energy consumption prediction for range calculation based on standard or memorized driving data. A navigation system in cooperation with the energy management system allows route planning based on energy consumption considerations and provides alternative routes for energy deficient conditions. A controller in the system with an associated display provides information to a vehicle driver concerning system status and controls various vehicle systems for increased energy efficiency.
