Abstract
The present invention integrates an on-board navigation system to provide energy management for an electric vehicle (EV) and a hybrid electric vehicle (HEV). The HEV control strategy of the present invention accommodates the goals of fuel economy while always meeting driver demand for power and maintaining the functionality of the traction motor battery system using battery parameter controllers. In the preferred embodiment of the present strategy, a vehicle system controller tightly integrates the navigation system information with energy management while en route to a known destination. Present vehicle location is continuously monitored, expectations of driver demand are determined, and vehicle accommodations are made. The system can be configured to includes as part of its present vehicle location data on road patterns, geography with date and time, altitude changes, speed limits, driving patterns of a vehicle driver, and weather. The vehicle accommodations can be configured to use discrete control laws, fuzzy logic, or neural networks.
