We first briefly review the history of electricity in the automobile, from its early beginnings to the electrical/electronic system in a modern, high-end car. The electrical system of a modern car will be described, with particular attention to the influence government mandates have had on its growth.
We next consider the electrical challenges facing automakers in the future as electrical loads increase. We identify the functions, old and new, which are expected to be electronically controlled by the year 2005. Included among these are steer-by-wire, brake-by-wire, active suspension, and electromechanical valve lifters.
Alternatives to the conventional 12 V architecture include both higher voltage dc and ac systems and multiplexed control. We consider the pros and cons of a few of these proposals, focusing on issues of cost, manufacturability, weight and efficiency.
We conclude with the demonstration of a tool developed for Mercedes-Benz to help make the complex trade-offs required in future electrical distribution system design.
