Algorithm and Control Strategies for Hybrid Electric Vehicle

In this paper, an approach to the problems regarding control of the electricity generation of hybrid electric vehicles (HEVs) is presented and an algorithm with the goal of minimization of fuel consumption is proposed. As increasing number of cars environmental pollution due to emissions from internal combustion engines (ICE), fuel consumption is increased. Currently, a number of researches are focused on the possibility of using fuel cells for producing energy from hydrogen. Electric Vehicles with fuel cells becomes a competitive alternative to the standard ICE which is used in today-s cars. Electric vehicles are zero emission vehicles, called ZEV type vehicles (Zero-Emissions Vehicles. The hybrid electric vehicles are very complex dynamic systems and have an important number of interconnected electrical systems to achieve the required operating performances. As the time control of a hybrid electric vehicle is complex, it is necessary to integrate all the elements in a high speed communication network to assure the distributed control of all the resources. In this study, overview of HEVs with a focus on hybrid configurations, energy management strategies and electronic control units are presented. The latest trends and technological challenges in the near future for HEVs are discussed.
