Network topology for chassis – potential of ethernet-based systems

Abstract

The increasing number of functions in modern vehicles like automobiles induces an increasing number of information to be interchanged between the diverse electronic control units (ECU) in the vehicle. Modern systems, like advanced driver assistance systems or infotainment systems, demand broadband communication channels. Beside the traditional bus systems, like CAN, MOST or FlexRay, Ethernet becomes more and more important for the in-vehicle data interchange, too.
