Traditional in-vehicle networks are statically deployed and configured during the car manufacturing process. However, the growing need for supporting new in-car traffic flows, e.g., to add new camera-based Advanced Driver Assistant Systems (ADAS) or infotainment applications, generates an increasing demand for bandwidth and requires the ability for re-configuring the bandwidth allocation among flows during the vehicle lifecycle. For this reason, this work proposes a partitioning system for Time-Sensitive Networking (TSN) that allows introducing new flows in the in-vehicle network without affecting the already existing ones. Moreover, the letter presents a simulative assessment of the proposed approach in a realistic automotive scenario.

Abstract

Traditional in-vehicle networks are statically deployed and configured during the car manufacturing process. However, the growing need for supporting new in-car traffic flows, e.g., to add new camera-based Advanced Driver Assistant Systems (ADAS) or infotainment applications, generates an increasing demand for bandwidth and requires the ability for re-configuring the bandwidth allocation among flows during the vehicle lifecycle. For this reason, this work proposes a partitioning system for Time-Sensitive Networking (TSN) that allows introducing new flows in the in-vehicle network without affecting the already existing ones. Moreover, the letter presents a simulative assessment of the proposed approach in a realistic automotive scenario.
