The rapid pace of development in automotive electrics and electronics has had a major impact on the equipment fitted to motor vehicles. This simple fact necessitated a complete revision and amendment of this authoritative technical reference work. The 4th Edition goes into greater detail on electronics and their application in the motor vehicle. The book was amended by adding sections on Microelectronics and Sensors. As a result, the basics and the components used in electronics and microelectronics are now part of this book. It also includes a review of the measured quantities, measuring principles, a presentation of the typical sensors, and finally a description of sensor-signal processing.
