Automotive multi-domain computing research: The first year of cross-domain integration is coming, and major manufacturers are accelerating the launch of new solutions

Zuosi Automobile Research and Development released the "2023 Smart Vehicle Multi-Domain Computing Industry Research Report".

With the development of automobile intelligence, the electronic and electrical architecture has begun to evolve from domain control centralized architecture to multi-domain converged computing and central computing. Under this development trend, OEMs, Tier 1 and chip companies have all ushered in new market opportunities.

In July 2023, SAIC launched VMC vehicle central coordinated motion controller technology, which is based on the central fusion motion control of the entire vehicle, making the vehicle's cross-domain control link shorter and more efficient in human driving or intelligent driving. Control the body and chassis;

In July 2023, BYD's first high-end intelligent driving assistance system  "Eye of the God" adopts a system architecture of a central computing platform and deep collaboration of regional controllers.

Major Tier1 suppliers rely on their own advantages to enter the field of multi-domain computing

Judging from the layout of major Tier1 suppliers, the layout of multi-domain computing is relatively flexible. Suppliers mainly rely on their own areas of advantage to deploy multiple domains such as body domain and chassis domain, body domain and cockpit domain, chassis domain and intelligent driving domain. Fusion.

United Automotive Electronics

United Automotive Electronics has established a specialized cross-domain control business department and signed strategic cooperation agreements with ecological partners such as Horizon, Neusoft Reach, Alabi, Lingmu Technology, and Tyco Electronics.

In December 2022, United Automotive Electronics launched the vehicle computing platform VCP, which uses the NXP S32G new generation SoC chip and integrates power domain and body domain related functions, including vehicle control, BCM, gateway, etc., and some projects integrate assisted driving functions;

In May 2023, United Automotive Electronics launched the vehicle motion domain controller VCU8.5 platform, which carried out systematic analysis and design for the needs of cross-domain integrated control and integrated functions such as EPB, FlexRay and Delay off.

mainland

In April 2023, Continental Group exhibited its cross-domain vehicle control high-performance computing unit for the first time. In addition to integrating the original body control and vehicle gateway functions, it also integrated chassis control applications. At present, Continental has won two local orders in China. The Haopin Hyper GT model of GAC Ion will become the first mass-produced car. It is expected that by 2024, the high-performance computing unit will be installed in more than 30 vehicles of multiple automobile manufacturers. On different models.

PATEO Internet of Vehicles

In June 2023, PATEO Internet of Vehicles successfully developed the first vehicle central computing platform (Central Computering Module, CCM). CCM expands computing power based on the central gateway and integrates smart cockpit functions, advanced assisted autonomous driving , body functions, and vehicle control functions, etc.

Key technical support for multi-domain computing: multi-domain computing SoC, cross-domain convergence software platform

At present, multi-domain integration is mainly considered from two levels: hardware and software. From the perspective of hardware integration, multi-domain integration currently mainly uses multi-SoC chip integration, which merges different domain controls into one box and consists of multiple SoC or It is composed of MCU , and different functions are supported by different chips. Achieving multi-domain integration on a single chip requires one SoC to complete different functions. At present, there are still certain challenges in achieving multi-domain integration on a single SoC chip.

Black Sesame Intelligence

In April 2023, Black Sesame Intelligence launched the C1200, the first product of the Wudang series, which is the first domestic car-grade cross-domain multi-functional integrated computing chip that can meet autonomous driving, smart cockpit, body control and other computing functions.

Wudang C1200 supports lock-step car-grade high-performance CPU core A78AE (performance up to 150KDMIPS) and car-grade high-performance GPU core G78AE. It has built-in mature and high-performance Audio  DSP module and a new generation of automatic processing of 1.5G pixels per second online. Research the NeuralIQ ISP module. In addition, C1200 also has built-in Security modules that support ASIL-D level Safety Island, National Security Level 2 and EVITA full, which can meet the highest reliability requirements of vehicle safety standards.

In addition to chips, the development of cross-domain integration also requires support from vehicle-level OS systems. At present, all functional areas of automobiles have not been fully connected, and there is no smart automobile operating system that can be directly applied for a long time in the world. This is an opportunity for domestic automobile OS manufacturers to overtake in a corner.

Zhida Chengyuan (ArcherMind Technology)

In April 2023, Zhida Chengyuan, a subsidiary of ArcherMind Technology, launched Fusion OS, a cross-domain integrated vehicle software computing platform - Fengsheng operating system. The product focuses on being compatible with operating systems from different domains. FusionOS quickly connects core functional domains such as smart cockpit, central control, and smart driving from the bottom to achieve a high degree of integration of various functional modules.
