On April 15, 2025, Li Auto officially published the 'Li Auto NovaRing OS Technology White Paper', comprehensively detailing the definition and future trajectory of automotive operating systems. The document delves into the technical architecture and core components of Li Auto NovaRing OS, an advanced automotive operating system tailored for the age of artificial intelligence. Comprising four fundamental pillars—intelligent vehicle control, autonomous driving, communication middleware, and cybersecurity systems—NovaRing OS represents a significant leap forward in automotive technology. Additionally, the white paper revealed an ambitious open source plan, whereby Li Auto intends to gradually release the system's code starting from late April. This initiative invites developers from around the globe to collaborate and contribute to the ongoing development of NovaRing OS. The objective behind both the system's release and the open source plan is to foster innovation and accelerate the evolution of automotive operating systems.
