There are a large number of possible configurations of engine, electric machine(s)2, clutches, gearing, and transmissions that can result in an HEV. These are grouped in four classes in this paper. Based on an examination of the architectures, these classes are: beltdriven starter/generators on the front of the engine, crank-shaft mounted motor/generators on the rear of the engine, series/parallel hybrids, and combination hybrids with a mixture of the previous configurations. BELT-DRIVEN STARTER/GENERATOR The first architecture is the entry level to hybridization. In this architecture the engine stop-start function is implemented with a starter/generator that is typically belt-driven. The Toyota Crown with the Toyota Hybrid System - Mild (THS-M) architecture shown in figure 1a is exemplary. The traditional alternator has been replaced Some powertrain features such as clutches and differentials are not included in these diagrams in order to keep them from becoming unduly complex. 2 A rotating electric machine can act as both an electric motor and an electric generator. 1 INTRODUCTION Hybrid vehicles have been in saleable production for over five years, with the first sales occurring in Japan. Many automakers have shown hybrid vehicle concepts at automotive shows. It is interesting, however, to examine in more detail which concepts have been chosen for further development and determined to be
