New E/E Architecture for e-Mobility - automotive computers are growing up
Ludger Fiege

Future mobility is mainly driven by the three megatrends
climate change, urbanization and demographic change. Electric
mobility allows for more efficient drive trains and
facilitates other, specialized vehicle and mobility
concepts. In order to exploit its full potential, however,
electric engines must be complemented with a consolidated
computing and communication architecture (E/E
architecture). Flexibility, determinism, and functional
safety are driven by needs to deploy advanced assistant
functionality (e.g. ADAS) and highly integrated smart
actuators (wheel-hub engines). We present an example of a
computing platform supporting plug and play as well as
safety-critical computing necessary for drive-by-wire
settings. The platform comprises central computing nodes,
operating system, Ethernet and a data-centric middleware. Its
goal is to offer a safe computing environment that liberates
application developers from dealing with systemic redundancy
and low-level communication details. Prototypes are being set
up in the RACE (Robust and Reliant Automotive Computing
Environment for Future eCars) project in two demonstration
vehicles.
