The evolution of complexity in automotive electric/electronic systems for forthcoming autonomous driven vehicles shows the need of re-thinking architectures, specially focused on modularity and scalability for cost-efficient vehicle implementations. In order to build actually safe and secure autonomous driven vehicles, three main aspects need to be considered: firstly, there is a clear demand for enhanced computational capabilities and communications in order to support the real-time execution of more and more sophisticated control algorithms. Secondly, a communication between the autonomous driving cars to the environment like pedestrians and other non-autonomous driving cars is needed. Finally, reliable and ultra-efficient power supply innovations fulfilling the demand of highly available and fail-safe E/E systems should be developed. In this paper, we examine the different trends for future E/E systems and analyze the advantages and disadvantages of each. Also, a possible timing / roadmap is explored.

Lear is one of four suppliers with global capability in providing complete automotive electrical distribution systems for traditional electrical architectures as well as emerging high-power and hybrid systems. We expect electrical content growth in vehicles to be above the rate of industry growth by approximately 5% per year for the foreseeable future reflecting macro industry trends. This content growth will require far more complex vehicle electrical architectures. To succeed in this segment, companies must be able to design and manufacture highly integrated and standardized architectures that optimize size, performance and quality. Software capability will remain a key differentiator due to the increasing complexity resulting from feature content growth and architecture sophistication.
