Preface xvii
drives. Their basic structure, operating principles, control and operational
characteristics are described from a traction system point of view.
In Chapter 7, the design methodology of series hybrid electric drive trains
is presented. This chapter focuses on the system-oriented design of the eng-
ine and the energy storage, the traction motor, the transmission, the control
strategy, and the power converters. A design example is also provided. As
an improvement to the first edition, various power converter configurations
have been added.
In Chapter 8, a design methodology of parallel hybrid electric drive trains is
provided. This chapter includes driving patterns and driving mode analysis;
control strategy; design of the major components, for example, the engine, the
energy storage, and the transmission; and vehicle performance simulation. In
addition to the material covered in the first edition, a constrained engine on
and off control strategy, fuzzy logic controlstrategy, and the concept of control
optimization based on dynamic programming have been added.
In Chapter 9, the operating characteristics, design methodology, and control
strategies of a series–parallel hybrid drive train are presented. This is a new
chapter in the second edition.
InChapter10,thedesignandcontrolprinciplesoftheplug-inhybridvehicle
are introduced. This chapter mainly addresses the charge sustaining hybrid
drive train with regard to the drive train control strategy, energy storage
design, and electric motor design. This is also a new chapter.
In Chapter 11, a design methodology of mild hybrid drive trains is
introduced with two major configurations of parallel torque coupling and
series–parallel, torque–speed coupling. This chapter focuses on operational
analysis, control system development, and system simulation.
In Chapter 12, different energy storage technologies are introduced,
including batteries, ultracapacitors, and flywheels. The discussion focuses
on power and energy capacities. The concept of hybrid energy storage is also
introduced in this chapter.
In Chapter 13, the design and control principles of hybrid brake systems
are introduced. Brake safety and recoverable energy are the main concerns.
The available braking energy characteristics, with regard to vehicle speed,
and the braking power in typical driving cycles are investigated. The brake
force distribution on the front and rear wheels is discussed for guaranteeing
the vehicle braking performance for safety. Furthermore, this chapter dis-
cusses the important issue of distributing the total braking force between
the mechanical and the electrical regenerative brakes. Two advanced hybrid
brake systems, including their control strategies, are introduced. This chapter
has been rewritten based on our recent research.
In Chapter 14, different fuel cell systems are described, with a focus on their
operating principles and characteristics, various technologies, and their fuels.
Specifically, vehicle applications of fuel cells are explained.
In Chapter 15, a systematic design of fuel cell hybrid drive trains is intro-
duced. First, the concept of fuel cell hybrid vehicles is established. Then, their
