  Abstract

This paper proposes a scheme to enhance the reliability and safety of an Ethernet-based braking system in vehicles, in the context of increasing in-vehicle Ethernet usage. A multi-queue mechanism with different priorities is applied to ensure the latency of brake signals, even in environments where various types of packets are transmitted over the Ethernet link. Additionally, to minimize data loss and recovery time in the event of a link failure, an improved method that addresses the limitations of conventional Ethernet redundancy techniques is proposed. Experimental results show that even under a high link utilization of 80%, packets meet the required latency constraints, and the recovery time after a link failure is reduced to 7.9 msec. The proposed approach demonstrates that a safe and highly reliable Ethernet-based brake system can be realized for ADAS and autonomous vehicles.
