Automotive Electronics – What Makes it So Special?
Automotive electronics consists of advanced sensors, control units, and “mechatronic“ actuators forming increasingly complex, networked vehicle systems. The article shows typical requirements for automotive electronic systems and their components. While quantities are typically lower than in mainstream (consumer/telecommunication/computer) electronics applications, requirements regarding safety (flawless design), reliability and durability, operating conditions and temperature cycles, as well as long-term supply capability are much higher. As a consequence, automotive electronics is typically using well-proven technologies derived from mainstream electronics with some time delay regarding their introduction. In addition, automotive specific technologies have been developed for highly integrated control units and “mechatronic” actuators. Some recent examples are given. The paper closes with a vision regarding further developments and trends in Automotive Electronics.
