Asynchronous Time-Sensitive Networking (TSN) Implementation in Automotive Zone-Based Architecture

Abstract

In the realm of modern automotive technology, vehicles now incorporate a range of advanced features, such as Advanced Driver Assistance Systems (ADAS), infotainment systems, and autonomous driving technologies. In response to the complexities of wiring and the imperative for improved network performance, a shift is occurring from conventional domain-based In-Vehicle Network (IVN) architectures to zone-based configurations. Similarly, there's a transition from traditional IVN protocols to Ethernet-based alternatives. Additionally, the adoption of Time-Sensitive Networking (TSN) is increasing, allowing for deterministic data transmission via Ethernet networks. The combination of TSN with zone-based architectures holds the potential for optimizing data transmission and reducing End-to-End (E2E) delay its variation (Jitter), hence ensuring the desired service level agreement (SLA) and enhancing the quality of experience (QoE). Our contribution involves simulating an IVN architecture where diverse Electronic Control Units (ECUs) are segregated into zones and interconnected via Ethernet. Our work includes implementing Asynchronous Traffic Shaping (ATS) standard in TSN for improved experiments with different ATS parameters and analyze their impact on E2E delay and jitter. The results demonstrate the efficiency of TSN, specifically ATS, in the IVN environment.
