Synthesis and Optimization of Automotive Information & Communication Networks

---

The demand for automotive driver assistance functions to provision improved safety, security and smarter as well as more ecological mobility is growing rapidly. Thereby, both the number and the topological structuring of 3lectronic control unit (ECU) networks have to be taken into account with a particular emphasis on considering high speed interconnect technology (like, e.g., Gigabit Ethernet) and advanced processing architectures (like multi-core processors and FPGA platforms). We will investigate the applicability of synthesis and convex optimization concepts, which are successfully applied to avionic electric supply networks, in the world of automotive ICT (information and communications technology) networks. Thus, complementary skills and expertise of both partners are combined to identify new solutions for demanding challenges: Analytic and heuristic design synthesis and optimization methods of UC Berkeley and the embedded system architecture and accelerator building block skills of TU Munich.

Final report:
First and foremost, we had good reasons to assume that the visiting student from TU München, who attended a guest semester at Prof. Sangiovanni-Vincentelli's group at UC Berkeley and also completed her Master thesis at UC Berkeley on the anticipated subject of joint cooperation, would have continued to stay at UC Berkeley to work on a corresponding PhD subject. This junior researcher would then have been the right and best conceivable candidate to facilitate an in depth dialogue between the two groups, come for a temporary research internship to Munich and act as contact point for doctoral candidates from the Munich team to visit UC Berkeley. However, what we did not anticipate is that for personal reasons (marriage) she left Berkeley to relocate with her husband to another US university.

In the following months and year, we made several attempts to identify members of our scientific staff and graduates to initiate a collaboration on the described or a closely related topic. This process has been complicated by the fact that the TU Muenchen focus in the related ARAMiS BMBF project consolidated on legacy CAN (Controller Area Network) virtualization support (rather than covering automotive network topology optimization as well) due to the demands of participating industry partners. Plus, during the last 9 months, research staff members from TU Muenchen, who would have qualified for an exchange with UC Berkeley, were fully occupied with the demonstrator integration for the final ARAMiS project review at Airbus, Hamburg, on April 29, 2015.

We still meet regularly at international conferences and have the continued desire to cooperate on Cyber Physical design methods, architectures and optimization techniques. We deeply regret to not have used the opportunities enabled by the BaCaTec funding for an exchange of junior researchers. However, love, unfortunate timing, and other project priorities hindered us from executing according to our plan. Sorry for the inconvenience caused and we seriously hope that another team can spend the money instead.
