A Multi-Domain Software Architecture for Safe and Secure Autonomous Driving

Abstract

This work aims at making Apollo, a popular autonomous driving framework, safer and more secure by designing a multi-domain architecture, where its components are split between a feature-rich domain running Linux and a critical domain running a real-time operating system (RTOS). The two domains are isolated by a hypervisor. We implemented a prototype where the control component has been ported from Linux to the Erika automotive-grade RTOS, and we discuss a number of challenges that have been faced in moving the component to Erika. The proposed solution has been experimentally evaluated by measuring the latencies involving processing paths passing through the control component.
