Introduction

Motor vehicles are now inconceivable without electronic control units and their associated sensors and actuators. Such components have revolutionised the automotive world. All essential vehicle functions are electronically controlled by systems and components that occupy only a tiny space. There are systems that control the function of engine and gearbox, the safety and security systems and a large number of comfort and convenience systems, and the number of ?intelligent? vehicle systems is growing at a rapid pace. Nor is there any foreseeable end to this trend.

Electronic control systems open the door to a vast array of possibilities. They improve vehicle safety and ride comfort. At the same time, they make vehicles more economical and kinder to the environment.

The triumphant advance of electronics has created a vocabulary of terms with which we are bombarded every day. It is becoming more and more difficult to understand what precisely those terms refer to. This publication in the Bosch Yellow Jacket ?Technical Instruction? series explains the specialist terminology of microelectronics in detail.

It starts with a short introduction followed by an explanation of the principles of semiconductor technology and how microelectronic components interact. A practical example of a circuit helps to consolidate the theoretical concepts described. This is then followed by a description of the development and production of control units.

Finally, the glossary provides a quick guide to the most important microelectronics terms.

The functions of the individual electronic systems (e.g.MED, EDC, ESP) are described in detail in separate publications in the Yellow Jacket ?Technical Instruction? series.
