Domain Controller Research: Exploration of Five Business Models, Tier1, Tier0.5, Tier1.5 or ODM?

Automakers accelerate the mass production of new E/E architecture platforms, and the penetration rate of domain controllers surges.

In addition to emerging carmakers that adopt new domain controller architectures from the start, conventional automakers have also stepped up the pace of using domain controllers in vehicles. Typical architectures include Geely Sustainable Experience Architecture (SEA), GAC Protoss Architecture, Great Wall E/E Platform (GEEP), BYD E3.0 Platform, and Volkswagen E3 Architecture. Through the lens of development planning, having achieved mass production of domain controller centralized architectures during 2021-2022, most OEMs will produce cross-domain fusion architectures in quantities between 2022 and 2023, and are expected to spawn centralized architectures from 2024 to 2025.

As OEMs accelerate mass production of new E/E architectures, domain controllers will be a big beneficiary. Taking autonomous driving domain controllers as an example, our statistics show that in 2021, at least 33 OEMs had over 50 production vehicle models equipped with autonomous driving domain controller products, and the number of such production models will surge in 2022.

According to ResearchInChina, China shipped 539,000 autonomous driving domain controllers for passenger cars in 2021, with a penetration rate of 2.7%, a figure expected to exceed 5% in 2022. It is conceivable that in 2025, the annual shipments will reach 4.523 million sets, and the penetration rate will jumped to 18.7%; the key driver will be the soaring shipments of L2+ driving and parking integrated domain controllers.

At present, more than 18 suppliers have launched over 20 L2+ driving and parking integrated domain controllers. In 2022, NOA is to be mounted on vehicles on large scale. Also the lightweight driving and parking integrated solutions using TI TDA4 and Horizon J3 chips have lowered 30% to 50% costs compared with the NVIDIA Xavier-driven solutions, helping ""NOA+ automated parking"" solutions to fully cover passenger cars priced between RMB100,000 and RMB200,000. The increasing number of passenger cars will support L2+ driving assistance functions such as ramp-to-ramp highway pilot, automated parking and home-AVP.

The L3/L4 high computing power domain controllers with built-in high computing power chips, e.g., NVIDIA ORIN-X, Horizon J5, Huawei Ascend 610, EyeQ6, Qualcomm Ride (8540+9000) and Renesas V3U, support high-precision sensors like LiDAR, 4D radar and multiple 8MP cameras, enabling intelligent driving in all highway, urban and parking scenarios. Currently, they are already in the early phase of small-batch shipments, and largely mounted on over RMB300,000 high-end models.

Explore domain controller business models, Tier1, Tier0.5, Tier1.5 or ODM.

Domain controller, as a core component for intelligent connected vehicle platforms, upwardly supports development of application software, and downwardly links E/E architecture and various system components. Its importance is beyond doubt. The competition in the domain controller market tends to be white-hot as multiple business models coexist.

Automakers are of course pleased to see the current competitive landscape. Their partnerships and collaborations with multiple suppliers help them build full-stack self-development capabilities. For automakers, this is also a process of trial and error so as to create a business development model that ultimately suits them.

In short, there are now mainly five domain controller design and production modes:

Model 1: OEMs outsource domain controllers. This model is firstly introduced by Tesla, and then adopted by emerging carmakers like NIO and Xpeng Motors. Tesla designs domain controllers, and entrusts the production to Quanta Computer and Pegatron. NIO seeks support from Wistron and Flex. As well as the most basic hardware manufacture, ODMs/OEMs already begin to set foot in software engineering covering domain controller underlying basic software, and BSP driver.

Model 2: Tier 1 suppliers provide domain controller production for OEMs. It is the most common model of cooperation in current stage. Tier 1 suppliers adopt the white box or gray box model; OEMs have the authority to develop the application layer for autonomous driving or intelligent cockpit. Chip vendors, Tier 1 suppliers, and OEMs often form close partnerships. Chip vendors provide chips and develop software stacks and prototype design packages; Tier 1 suppliers provide domain controller hardware production, intermediate layers, and chip solution integration. Typical cooperation cases of this model include Desay SV + NVIDIA + Xpeng Motors/Li Auto/IM Motors, and ZEEKR + Mobileye + iMotion.

Model 3: Tier 1.5 suppliers born in the trend towards software and hardware separation concentrate their efforts on domain controller basic software platforms. Upwardly, they prop up OEMs to hold the independent development authority of systems, and downwardly integrate Tier 2 suppliers’ resources such as chips and sensors. As the originator of this mode, TTTech is currently valued at more than USD1 billion, and introduces key shareholders like Audi, Samsung Electronics, Infineon and Aptiv.

TTTech provides the MotionWise software platform that includes tools and middleware. Technomous co-funded by TTTech and DIAS Automotive Electronic Systems (a company under SAIC) is SAIC’s major supplier of autonomous driving domain controllers. In China, Neusoft Reach, EnjoyMove Technology, ArcherMind Technology, Megatronix Technology, ThunderSoft and the like all tend to enter the domain controller supply chain from software.

Meanwhile, Tier 1 suppliers are also playing the role of the Tier 1.5. For instance, in the field of cockpit domain controllers, Bosch which specializes in underlying cockpit software systems outsources hardware production and ecosystem construction to its partner, AutoLink. For Tier 1 suppliers, they are best able to follow the market development trend by providing a range of solutions such as software, hardware, and software and hardware integrated solutions.

Model 4: Tier 0.5 suppliers are born of OEMs’ needs for full-stack self-development capabilities. Tier 0.5 suppliers tightly bound with OEMs will partake in the whole process of OEMs from R&D, production and manufacture to even later data management and operation. There are three types of Tier 0.5 suppliers:

(1) Some OEMs spin off their parts and components division for independent operation. Examples include DIAS Automotive Electronic Systems under SAIC, Nobo Automotive Technology and Haomo AI under Great Wall Motor, and ECARX under Geely;

(2) Some OEMs seek partnerships with Tier 1 suppliers to establish joint ventures, for example, Anhui Domain Compute co-founded by Hongjing Drive and JAC, and FulScience Automotive Electronics, a joint venture of Desay SV, FAWER Automotive Parts and FAW.

(3) Chip vendors transform into Tier 0.5 suppliers. In the context of chip shortage, chip vendors have a bigger say, and even OEMs have to bypass Tier 1 suppliers to purchase directly from them. Chip vendors no longer feel fulfilled in the role as Tier 2 suppliers, and are trying to develop a strong bond with OEMs. Chip vendors participate in OEMs’ vehicle model development at the very beginning. For example, Mobileye and Geely built strategic cooperation; after acquiring Veoneer, Qualcomm will work harder to roll out autonomous driving and cockpit cross-domain fusion computing platforms; NVIDIA DRIVE Hyperion 8.1 platform is compatible with both autonomous driving and cockpit, and the chip vendor even attempts to join hands with OEMs on an autonomous driving business profit sharing model.

Model 5: system integrators outsource domain controllers to ODMs/OEMs, especially providers of autonomous driving system solutions and intelligent cockpit software platforms. For instance, Baidu’s ACU is produced by Flex, and Haomo AI also cooperates with Flex. Even many autonomous driving start-ups may adopt this model, that is, with ODMs/OEMs providing the automotive OEM hardware production capacity supplement, they supply complete ""domain controller + ADAS integrated development"" solutions to OEMs, aiming to be better able to compete with conventional Tier 1 suppliers.

In the age of software-defined vehicles, full-stack software system solutions will be the key to gaining competitive edges for domain controller providers.

In general, we believe that against a background of software and hardware separation, the full-stack software system development capabilities will play a key part in the future contest. For domain controller providers, the key to gaining competitive edges is the continuous efforts to enrich and build underlying platforms (software-defined hardware, data services, information security, operating systems, etc.), middle-layer platforms (middleware, AutoSAR, chip adaptation, etc.), and application-layer platforms (human-machine interaction (HMI), algorithms, software stack, etc.).

In terms of intelligent cockpit, in PATEO CONNECT+’s case, the company has five core technology platforms: Operating System, Intelligent Voice, Hardware, Map, and Cloud Platform. Based on SOA and software-defined vehicles, PATEO CONNECT+ provides software application development and operation for users in intelligent cockpit, intelligent driving, and body control domain.

The in-depth cooperation with large automakers such as FAW, Dongfeng Motor, BAIC, Geely and SAIC-GM-Wuling allows PATEO to rapidly expand its intelligent cockpit division based on its telematics business. Its solutions from domain controllers and operating systems to hardware, software and cloud three-end intelligent cockpit integrated solutions help automakers create personalized driving experience for users.

At the hardware end, PATEO’s intelligent cockpit domain controller hardware platforms cover Qualcomm 8295/8155, NXP i.MX8QM, MTK8666, and homemade X9H, among others. Its products are led by:

In April 2020, PATEO's i.MX8QM-based intelligent cockpit product was first mounted on production model BEIJING X7. The use of hardware isolation technology supports operation of Linux + Android dual operating systems on the same hardware.

In April 2022, PATEO Qinggan 8155 platform fitted on Voyah Dreamer was launched on market. This platform with QNX Hypervisor technology allows operation of QNX + Android dual operating systems on the same hardware. In June, the platform became available to NETA U, NETA Auto’s new flagship model. It enables the perfect integration of dashboard and entertainment system, and thus cuts much of the hardware and software cost of intelligent cockpit domain controllers.

PATEO CONNECT+ is designing and developing the next-generation Qualcomm 8295-based intelligent cockpit platform with higher levels of domain controller integration. The 8295 chip that supports three-domain fusion will favor a sharp reduction in the cost of the cockpit. Compared with the conventional modes of multiple domain controllers and multiple wire harnesses, the three-domain hardware integration based on the 8295 automotive chip platform takes on integrated control over multiple units such as streaming rearview mirror, central display, air conditioner, and lamps. This mode will save the cost of quite a few domain controllers and intelligent component control units. With this mode, PATEO will derive diverse lower-cost solutions from Qinggan 8295-based cockpit when cooperating with different partners, assisting automakers in slashing their cost. PATEO will expand cooperation and develop solutions in such fields as vehicle intelligence, intelligent vehicle connectivity, SOA, cockpit integration, and central controller-based multi-domain fusion. This new cockpit platform is expected to be rolled out on market with related vehicle models in 2023, providing leading immersive intelligent driving experience for automotive industry.

At the software end, with long-term efforts to develop intelligent cockpit domain controllers from cloud platform to terminal platform, PATEO has built end-to-end design and development capabilities. The cloud end involves technical solution platforms such as CP access, account management, data management, and FOTA. The terminal design and development range from cockpit operating systems to HMI.
