Within the last two decades, the development of electric / electronic (E/E) systems in the automotive domain was subject to a significant change: Starting with increasing E/E content in “stand-alone features” like engine control or brake system (e.g. E-Gas or ABS) realized in one single Electronic Control Unit (ECU) with directly connected sensors, networks (like the CAN-Bus) were introduced to connect the different subsystems. Later on, distributed features were developed in which the algorithms of the realized feature are spread over several ECU’s.
