There are various hybrid powertrain architectures which are in use. This chapter discusses the principles of a few advanced hybrid electric powertrain architectures. These architectures include the popular GM two‐mode hybrid and its variations, dual‐clutch‐based hybrid, Tsai's hybrid, Zhang's hybrid, Renault hybrid, and Timken hybrid. The chapter presents the steady state operating modes and torque/speed relationships and also discusses the hybrid electric vehicles (HEVs) powertrain dynamics for the Toyota hybrid transmission. It should be noted that most planetary gear‐based HEVs, including the Toyota, Ford, and GM two‐mode hybrids, do not include a separate dedicated starter for the engine. The engine is started by one of the motors/generators at an appropriate condition. In the case of the Toyota and Ford hybrid systems, an additional clutch between the engine and the planetary gear system could help smooth the acceleration. Fuzzy logic, dynamic programming, and wavelet transforms are popular in the power management of complex hybrid vehicles.
