The powertrain is at the heart of vehicle design; the engine
- whether it is a conventional, hybrid or electric design
- provides the motive power, which is then managed and
controlled through the transmission and final drive components. The
overall powertrain system therefore defines the dynamic performance
and character of the vehicle.

The design of the powertrain has conventionally been tackled by
analyzing each of the subsystems individually and the individual
components, for example, engine, transmission and driveline have
received considerable attention in textbooks over the past decades.
The key theme of this book is to take a systems approach - to
look at the integration of the components so that the whole
powertrain system meets the demands of overall energy efficiency
and good drivability.

Vehicle Powertrain Systems provides a thorough
description and analysis of all the powertrain components and then
treats them together so that the overall performance of the vehicle
can be understood and calculated. The text is well supported by
practical problems and worked examples. Extensive use is made of
the MATLAB¯(R) software and many example programmes
for vehicle calculations are provided in the text.

Key features:

* Structured approach to explaining the fundamentals of
powertrain engineering

* Integration of powertrain components into overall vehicle
design

* Emphasis on practical vehicle design issues

* Extensive use of practical problems and worked examples

* Provision of MATLAB¯(R) programmes for the reader to
use in vehicle performance calculations

This comprehensive and integrated analysis of vehicle powertrain
engineering provides an invaluable resource for undergraduate and
postgraduate automotive engineering students and is a useful
reference for practicing engineers in the vehicle industry
