Abstract
In this paper, simulation and test results of a low floor Series Hybrid Electric Vehicle running in BUSAN city driving mode are presented. Hyundai Heavy Industries Company and Daewoo Bus Corporation have jointly developed a prototype Series Hybrid Electric Bus (SHEB) to evaluate vehicle performance together with fuel economy as a part of feasibility study on hybrid bus operation. It is found that the fuel efficiency of SHEB is 22% higher than that of a conventional internal combustion engine bus and our GENSET control method is quite effective in maintaining that battery’s State of Charge (SOC) during bus driving.
