Abstract :
This paper describes the mathematical modeling, analysis, and simulation of a dynamic automatic manual layshaft transmission and dry clutch combination powertrain model, and corresponding coordinated control laws synthesized using a conventional SI ICE powerplant-alternator combination, a dry clutch and manual transmission/differential, variable field alternator, brakes, and complete vehicle longitudinal dynamics with tire-road interface characterization. The conventional power train model is validated using experimental test data confirming accurate emulation of dynamic components of the pre-hybridized vehicle. In addition, the development of dynamic series and parallel hybrid electric vehicle (HEV) powertrain models and corresponding coordinated control laws are described. A discussion of the key issues associated with coordinated control law development is provided. Simulations of the dynamic behavior of two types of series HEVs are shown
