Architectural design on hypervisor-based guest OSs and SafetyRTOS in automotive platform
Kukhyun Kim · 2023
Automotive platform consists of complex and diverse components, which are Advanced Driver Assistance System (ADAS) and In-Vehicle Infotainment (IVI), developed plenty of operating systems by companies, depended on a variety of technologies, and satisfied different requirements in terms of both security and functional safety. The Automotive Hypervisor solution is multi-domain controller that can run multiple operating systems with a single processor. The instrument cluster operates on host OS such as Linux Container (LXC), QNX, and Xen and the IVI center console and ADAS operates on another OS such as Android, WebOS, and Linux. Automotive platforms should improve the integration of various OSs and operate more efficiently and securely. In this paper, we propose hypervisor-based guest OSs architecture that allows improve efficient performance system for automotive platform with safety. We also concept high level SW design architecture of safety real time operating system (SafetyRTOS) to operate functional safety requirements efficiently.
