Developments in advanced driver assistance systems (ADAS) are creating a new approach to in-vehicle network (IVN) architecture design. With current vehicles containing at least a hundred ECUs, the current distributed network architecture has reached the limits of its capabilities. The automotive industry is now focusing on a zonal or domain controller architecture to simplify network design, reduce weight and cost, and maximize performance.
A domain controller can replace the functions of many ECUs to enable high-speed communications, sensor fusion, and decision making, as well as support high-speed interfaces for cameras, radar, and LiDAR sensors. This poster graphically depicts the development of IVNs from the past to the present and future and then provides guidance on how to test them.
