Energy-based approach to model a hybrid electric vehicle and design its powertrain controller and energy management strategy

Abstract

This paper presents a methodology to develop an energy management strategy that would quasi-optimize the fuel consumption of a parallel Hybrid Electric Vehicle in real-time operations over the entire trip. Hence, the main highlight of this study is the presentation of a coherent energetic modeling technique to simulate a parallel hybrid electric vehicle, by providing an energy-based representation of the powertrain components; presenting a systematic technique to design the vehicle controller structure and designing (through a comprehensive global-optimization approach) a rule-based EMS showing close-to-optimal consumption results over the entire scheduled trip.
