Hybrid Electric Vehicle (HEV) research has an innovative and productive history. Though the concept appeared decades earlier, research toward hybrid electric vehicle production did not begin in the U.S. until 1993. The Department of Energy in collaboration with Ford, Chrysler, and General Motors, launched a five-year study that culminated in each auto company unveiling a hybrid prototype. In the years that followed, many automakers, both foreign and domestic, have presented hybrid concepts, prototypes, and production models. Today, the Honda Insight, Toyota Prius, Honda Civic (Hybrid) are market ready examples of hybrid technology. There are three different vehicle configurations of Hybrid systems: -Series Hybrid: In this configuration, the Engine operates the generator to provide electricity to the electric motor and to re charge the battery; -Parallel Hybrid: Both the engine and the electric motor are mechanically connected to the wheels and can directly provide power to the wheels; -Series-Parallel Combined System: This powertrain configuration consists of two power sources that are connected to the driveline: 1) a combination of engine and generator subsystems using a planetary gear set to connect to each other, and 2) the electric drive system (motor, generator, and battery sub systems). The battery subsystem is an energy storage system for the generator and the motor. In this paper, a fuzzy battery power controller is described for a powersplit-HEV. Using the Driver demand power, the battery state of charge, and the vehicle acceleration, a set of rules has been developed, in a fuzzy controller, to minimize fuel consumption and emissions. When the engine is 'on', the fuzzy controller main function is to determine the battery power charge or discharge levels in a way to optimize the engine operating efficiency and the total powertrain system efficiency. Matlab Simulation models and vehicle test data have been used to evaluate the performance of the controller. Comparison between the existing controller and the addition of this fuzzy controller to the existing controller reveals that the proposed fuzzy controller is effective over the entire operating range of the vehicle in terms of performance and fuel economy and emissions.
