Challenges
External Communication
Flexibility
Time to market
Vehicle Lifetime
Communication Bandwidth Differentiation
Driver expect new features and
improvements in a fast pace
Future E/E system needs to allow
swift SW sharing & introduction of
new innovations
Leads to higher data traffic and
significant security risks
OEM wants to focus on
differentiating instead of
non-differentiating features
Inter-domain and cross-domain
communication bandwidth not
sufficient for future data traffic
OEM wants revenue streams during
the whole vehicle lifetime
