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. This is to model all artifacts that have influence on systems performance, reliability, and cost, but to avoid wasting efforts on the small things that can be handled later in the supplier detail development.

The presentation also looks at the requirements for the tools to support such a system approach with aspects like data model, variant handling, multi-user, etc. It will show the pragmatic solution building blocks available.

Furthermore, it will look at how OEMs can benefit from the implementation of the E/E Architecture approach in terms of quality, cost savings, and efficiency increase.
