The pace of development has inspired four revisions of this book in roughly ten years to avoid obsolescence. Rarely in history have technical developments moved at such a pace. Electronics have recently been incorporated on new automotive subsystems and have become standard implementation on many others. Such features as antilock braking systems and airbags could only be achieved practically through the use of electronics. These features are rapidly becoming standard features owing to strong pressures in the highly competitive North American automotive market. The first edition of this book was devoted primarily to electronic engine control because this was the chief application at that time. A number of automotive systems which were discussed in the chapter on the future of automotive electronics in the second, third, and fourth editions are now in production. These systems are presented in the appropriate chapters of this fifth edition. This latest edition covers most of the automotive subsystems incorporating electronics except for entertainment systems. These systems have been omitted partly due to space limitations and because automotive entertainment systems are closely related to home entertainment systems, which are discussed in many excellent publications. In its revised form, this book explains automotive electronics as of the late 1990s. It should prepare the reader for an understanding of present as well as future developments in this field into at least the early part of the next century. William B.
