The future of E/E architectures

The increasing feature sets of vehicles combined with high volumes of data have manifested in increases in the number of ECUs and sophistication of the communication bus networks needed to accommodate these rapidly changing requirements.

New ways of accommodating increasingly sophisticated feature sets are thus needed. This report benchmarks current electrical/electronics (E/E) architecture and explores expected new and novel arrangements for future in-vehicle networks in terms of signal and electrical power distribution over the next 15 years. The research study highlights evolution of vehicle's EE architecture and throws light on the transition from flat, distributed architecture to centralized zonal architecture.

The report includes dedicated sections on vehicle networking protocols, electrification strategies for ICE and BEVs, domain controllers, and gateway modules. It also includes case studies on the evolutionary migration to new architectures with domain controllers.
