Abstract
Our goal in this study is to develop the supervisory control strategy for a hybrid bus system, which is able to control the power distribution between an engine and an electric motor more efficiently, because the fuel economy of hybrid system could change depending on the supervisory control of hybrid control unit. In case of the bus transporting system, there is some information that can be used to optimize the fuel economy on a supervisory controller like altitude, vehicle speed and set routes recorded from a GPS receiver. In this paper, we present the supervisory control algorithm for the parallel hybrid bus, which is using the Power Split Ratio (PSR) between two power sources. The PSR line can be derived from the analysis results of Dynamic Programming theory that is one of the optimal control concepts. The fuel economy saving results shows that the parallel hybrid bus can save its fuel consumption about 15∼40% compared with the conventional bus system.
