Design Requirements for Automotive Reliability
1960: Vision
source: R. Bosch GmbH, Dr. Callsen, „The Importance of Semiconductors for the Electrical Vehicle Equipment“. FISITA congress, 1960.
“The development of semiconductors is just at the beginning… Using semiconductors, ideas like electronic gasoline injection as well as control systems that allow steering, accelerating and braking through a small control stick, or steering systems that guide the car automatically on the road, or radar units that show obstacles even in dense fog, as well as some others, can become reality… Electronics is starting to change and to improve the electric vehicle system and is thus adding increased safety to the car.” Automotive Electronics

Challenges for Automotive Electronics Î
Convergence of Systems - new functions often require networking of different systems - systems accessible from outside (wireless) - need to integrate subsystems of different suppliers
Î
How to keep vehicles – despite their increasing electronics content – affordable for the consumer ?
Î
How to assure extended lifetime reliability and availability of the vehicles despite the underlying very complex electronic systems ?
