Exploring the evolution of AI driven vehicle digitization, where intelligent platform development, seamless software-electronics integration, and scalable architectures are accelerating the future of L1–L5 autonomy. Powered by 5G today and evolving toward 6G, alongside emerging NTN (Non-Terrestrial Networks) ISAC (Integrated Sensing and Communication), AI-enabled systems are redefining ADAS, sensor fusion, V2X communication, and real-time vehicle intelligence. Considering the transformation of platform architecture, cloud connectivity, IoT integration, OTA updates, and centralized domain control — enabling smarter, safer, adaptive, and continuously learning software-defined vehicles.
