The registration of mopeds and motorcycle is increasing early. With compare to gasoline and diesel passenger car, mopeds and motorcycle generates more emission gas. So it is important to develop motorcycle with hybrid powertrain. With hybrid electric powertrain, mopeds and motorcycles might have better fuel economy and less emission gas. This paper proposes control strategies of 3Wheel hybrid electric vehicle. For develop the control strategies, two vehicle models are constructed. One is conventional internal combustion engine type vehicle model and another is hybrid electric vehicle model(HEV). HEV model is constructed with electric components like motor and battery. A test vehicle is constructed to develop 3W HEV.

It is important to develop a model that can characterize dynamic features of transmission in shifting phase to evaluate performance of a controller for an automatic transmission system. And it is very essential to develop a technique that realize dynamic features of clutches that construct a transmission to develop that model. Moreover that model needs to be simulated in real time or semi-real time. But other dynamic analytic simulator software like MSC.ADAMS or AMESim can’t satisfy that feature. So in this research we develop a clutch analisys method that determines stick and slip state of clutches included in a transmission based on fixed step solver.
