This chapter provides engineers with more practical, up‐to‐date, and comprehensive models of a hybrid electric vehicle (HEV) system. An HEV transmission must be able to handle engine‐only driving, electric‐only driving, and a combination of the two. In addition, it also has to support stop‐start functionality, the use of regenerative braking, and shifts in the internal combustion engine's (ICE's) operational zone. The chapter discusses a generic model of automatic transmission which includes a torque convertor, clutches, a gearbox, and a controller with a complex control strategy. It introduces the lever analogy diagram that is a very useful tool when analyzing a gear train that has more than two connected planetary gear sets. Planetary gear sets are fundamental components of an electronic continuously variable tranmission (ECVT), and it is quite cumbersome to analyze their kinematics by means of the traditional torque and speed calculation method.
