Today, Hyundai Motor held its first developer conference offline, while the keynote was streamed live online. Personally, I watched the keynote online and gathered impressions from YouTube and news articles. I’d like to briefly share my thoughts by comparing it with other automotive OEMs.
Overall, the conference felt centered around 42dot. Hyundai collaborated with partners such as Samsung Electronics, Naver, Unity, Google, and Uber, presenting together.
Pleos
Pleos is a combination of the Latin word "Pleo," meaning "more," and "OS," short for "Operating System." It reflects Hyundai Motor Group's vision of enhancing technology and achieving better mobility by adding user-centric value to the movement of people and objects.
It is an overall architecture diagram with a highly abstract view. It includes the OS for ECUs across the entire vehicle and strongly emphasizes AI. It also appears that APIs will be provided to give developers access to a significant amount of data.
CODA E/E Architecture
Hyundai Motor and many other OEMs are moving toward a Zonal architecture. The system uses a 48V power supply, with Zonal controllers supporting ASIL-B/D. The High-Performance Vehicle Computer (HPVC) supports ASIL-B and handles IVI, ADAS, and more.
With this architectural shift, the number of ECUs has been reduced by 66%, and cable usage has been significantly minimized, achieving both cost and weight reductions. However, as always mentioned, this leads to a major challenge: concentrating software in a single unit (HPVC), which makes managing complexity and dependencies incredibly difficult.
Even now, integrating digital cockpits and infotainment systems causes many dependency issues during development. It’s hard to imagine the challenges that will arise when ADAS is also integrated.
I watched an Android Automotive-based demo on the MOCA (KOREAN Youtube) channel (https://www.youtube.com/watch?v=6f7ecnebcyY), and the UI seemed to run quite smoothly and naturally. The specific SoC used has not been disclosed yet. Of course, since this is just a PoC demo, there’s still a long way to go before mass production.
This summer, when I visit Korea, I plan to stop by 42dot in Pangyo. It would be great to have discussions about these developments.
Pleos Connect
Pleos Connect is a next-generation infotainment system based on AAOS (Android Automotive OS). It is designed to enhance connectivity between mobile devices and vehicles, allowing users to seamlessly access their familiar apps and content within the car.
It features a large central display similar to Tesla, running AAOS. In addition to software updates, it provides an interface that allows hardware to be added like accessories. It feels somewhat reminiscent of the LG G5 Friends concept.
Pleos Partnership
Samsung Electronics announced plans to integrate Hyundai Motor Group's SDV vehicles with SmartThings, creating a unified ecosystem that connects smart homes, mobile devices, and vehicles. This initiative aims to extend AI Home-based personalized experiences to cars.
With Google, Hyundai presented various technical scenarios to enhance in-vehicle user experiences by linking AAOS-based SDV vehicles with Google services. Additionally, Google stated that it would expand its collaboration with Hyundai Motor Group on AI-powered next-generation navigation and infotainment technologies.
Naver introduced optimization strategies for AI, search, maps, and content services in the SDV environment. The company plans to apply AI in vehicles to understand users better and seamlessly connect mobile and in-car experiences through personalized services such as voice search, AI briefings, and destination recommendations.
Socar proposed ways to enhance the convenience of car-sharing services by integrating Hyundai Motor Group’s SDV open platform with vehicle data. Socar plans to offer ultra-personalized features via APIs, including remote door unlocking, climate control settings, safety diagnostics, and automatic seat adjustments. Additionally, by syncing cloud services with vehicle user profiles, Socar aims to deliver purpose-driven, tailored experiences.
Unity highlighted the potential of expanding in-vehicle gaming and content experiences in the SDV environment and explored the application of real-time 3D engines. The company introduced a collaboration model between the Pleos open ecosystem and the Unity platform, aiming to simplify the creation and distribution of in-car games and content. Through seamless hardware integration, Unity seeks to provide customized in-car entertainment and real-time 3D-based infotainment experiences.
Pleos Connect Platform Milestone
The SDV Pace Car will be used for validation, with a full-stack SDV expected to be demonstrated in 2028. Before that, Pleos Connect, an AAOS-based infotainment system, is set to be released next year and integrated into vehicles.
Summary
I’m part of several group chats related to the automotive industry, and many participants mentioned that the venue felt too small for the overall scale of the event. Given the nature of group chats, rather than overwhelmingly positive reactions, there were quite a few critical opinions—such as concerns about the gap between demos and mass production and whether 42dot can truly deliver.
In terms of direction, Hyundai appears to be aligning with other automotive OEMs and using this developer event to present its vision. Personally, I believe Hyundai has the strength and capability to make this work. The name "Pleos" still feels unfamiliar and doesn’t roll off the tongue easily, but it seems to serve as the overarching brand for Hyundai's OS—similar to MB.OS—while the actual implementations will vary across different controllers, such as infotainment, ADAS, and more.
This summer, when I visit Korea, I plan to meet with various industry professionals to exchange insights while maintaining confidentiality. I’ve already had a light conversation with someone connected to LG Electronics' SDV division, and I plan to dive into deeper discussions later.
