In the last two decades, fuel economy and emission reduction have been the major research subjects in automobile industry. Due to appropriate interaction between engine and electrical motor, hybrid vehicle has become a more efficient tool in the transportation systems. Hence, the operation methods for the incorporation of the two subsystems would play a key role in the relevant research field. In this paper, a fuzzy prediction controller incorporated with a fuel economizer for a series hybrid vehicle will be developed. Simulation results are also given to validate the controller.
