Today, the electrical and electronic system in vehicles is one of the core systems - with big influence on functionality and quality. And it is - besides the engine - the most expensive part of the vehicle. The ongoing pressure on saving cost (and weight) is also a major challenge to the developers of the E/E system. Every cent saved on a car creates substantial savings, since most systems are applied to platforms with several million cars per year. A cost saving target of $20 per car (without negative influence on the functionality and quality) sounds impossible for most insiders. This presentation identifies some areas where the potential for savings is not (fully) exhausted. For each area there are examples out of the global automotive industry where substantial savings with $10 or more have been achieved. Furthermore, the presentation will propose approaches for “Value engineering” and “Redesign2Cost”.

The electrical and electronic system in vehicles with all its components has become more and more complex. Many different stakeholders are involved and more and more parts of the development process have been shifted to the suppliers. This outsourcing results in substantial savings on the OEM side, but brings additional challenges to manage the overall system and keep the core IP within the OEM. This presentation shows an approach that was adopted recently by several OEMs. It is called the “E/E-Architecture” process and applies the principles of system engineering according ISO/IEC15288. It shows the starting point by managing the requirements and how to use functions as the source of the truth over the entire design process. During the E/E Architecture phase, it is important to concentrate on the strategic design aspects.
