In various system areas of traditional automobiles, such as steering, power, and in-car entertainment, they are all managed and controlled by various ECUs.
Modern cars may have 70-100 ECUs. As the number of ECUs continues to increase, the complexity of automotive electronic systems is becoming higher and higher, and stability will also face challenges.
Such a separate system may have multiple operating systems, with different codes running on different ECUs. In this case, the cost and resource overhead of control and communication of the overall system will be very high, and the complexity of both hardware and software will be very high.
As the market promotes the development of autonomous driving technology and the transformation of the industry, there is a need to reduce hardware costs and simplify system control in the field of domain controllers. Under this demand, the architecture of traditional automotive control needs to make some changes.
Under the architecture of the domain controller, each functional component becomes an independent domain. Functional components such as ADAS, smart cockpit, and chassis control are processed and controlled by dedicated domain controllers.
At the same time, domains can also be securely isolated from each other. In addition, the use of more integrated hardware and domain controller technology can effectively reduce the hardware cost of the system.
The following is a disassembly and introduction of Huanyu Zhixing's autonomous driving domain controller TITAN 4 product, regarding the system composition and functional units of the multi-domain controller.
First of all, from the perspective of the external hardware interface, in addition to the necessary vehicle-mounted interfaces, many interfaces are reserved for convenient debugging, such as RJ45 Gigabit Ethernet, HDMI, and USB interfaces.
In terms of cameras, there are 8 Fakara code C connectors, supporting up to 8 video inputs for forward perception and surround vision.
With the built-in u box positioning module, the controller can support receiving RTK differential positioning signals, providing smart cars with high-precision positioning functions that are superior to consumer products. The interface for the positioning antenna is also reserved, also using the Fakara code C connector.
It has a built-in 4G chip module and a reserved interface for the 4G signal antenna to provide network access services for smart cars.
Others, such as power supply, CAN, LIN, and UART are integrated into an integrated wiring harness interface; the group supports up to 10 CAN, 2 LIN bus interfaces, 4 UARTs, and 1 Flexray bus interface.

Software Components:
The software running on the multi-domain controller will have different configurations depending on the level of system functions. The more mature L3-level autonomous driving multi-domain controller currently processes a combination of software modules such as vision + millimeter-wave radar + vehicle control.
However, due to the more complex scenarios and working conditions for L4 level autonomous driving, there is currently no relatively mature software system for multi-domain controllers of embedded solutions.
Visual algorithms, lidar point cloud processing algorithms, perception fusion algorithms, and even complex behavior prediction algorithms that meet real-time performance requirements need to be run on the GPU.
The autopilot software running on TITAN 4 has been refactored and gradually adapted to the AutoSAR architecture. Phased progress has been made. The Athena autopilot software previously running on TITAN 4 uses multicast to communicate between network elements.
The architecture is suitable for OEM manufacturers' pre-research projects. As market demand develops, high-level autonomous driving software systems also need to gradually comply with automotive specifications.
