EVOLUTION OF IN-VEHICLE NETWORKS
Developments in Advanced Driver-Assistance Systems (ADAS) are creating a new approach to In-Vehicle Network (IVN) architecture design. With today’s vehicles containing at least
a hundred ECUs, the current distributed network architecture has reached the limit of its capabilities. The automotive industry is now focusing on a domain or zonal controller architecture
to simplify network design, reduce weight and cost and maximize performance. A domain controller can replace the functions of many ECUs for enabling high-speed communications,
sensor fusion and decision-making, as well as supporting high speed interfaces for cameras, radar and LiDAR sensors.
