Performance Analysis and System Modelling of Ethernet-based In­ Vehicle Communication

University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

Abstract: While vehicle technology is rapidly advanced, advanced driver assistance system (ADAS) stays in focus. However, all of these growing automotive applications are driving up the bandwidth requirements, therefore vehicle networks require higher bandwidth and more deterministic real-time guarantees than before.Switched Ethernet is widely used for all kinds of applications, and it gradually moves into the automotive domain. The new specification of the IEEE 802.1 Audio/Video Bridging (AVB) standard provides the QoS features needed for ADAS data streaming.In this work, we study and analyse Ethernet-based invehicle communication of both legacy Ethernet and AVB Ethernet through a simulation approach to verify the automotive network performance. Furthermore, a system engineering approach is used to achieve a more model-based design of simulation and developing prototypes in the future.
