In recent years, more and more cars are built upon mechanical platforms and, thus, enable to reduce development time and cost due to increased reuse of already developed mechanical components like combustion engines or suspensions. But, to support a seamless platform-based development of the whole car, also the Electric/Electronic (E/E) architecture and the included vehicle electronics have to be build based on E/E architecture component platforms. There, component manifestations like different hardware versions of an Electronic Control Unit (ECU) should be reused whenever possible and beneficial. To enable this, the work at hand proposes to use a multi-variant Design Space Exploration that enables an automatic multi-objective optimization of the E/E architecture component platform as well as the individual variants’ E/E architectures at once. This allows to enhance the E/E architecture design …
