Domain based centralized EE architecture
Overview of the Domain Controller Market
In 2018, based on the domain controller technology provided by Delphi, the zFAS controller developed by Austrian
TTTech company was first applied in the Audi A8. Weishitong Company has launched the SmartCore domain controller,
which integrates functions such as information entertainment, dashboard, information display, HUD, ADAS, etc. These products have
pioneered commercial functional domain controller products, and major Tier 1 suppliers around the world have followed suit,
gradually developing the entire domain controller market.
In the domestic market, companies such as Huawei, Desay SV, Hangsheng Electronics, and Neusoft have also launched DCU
solutions, which have been adopted by domestic car companies. For example, the intelligent coupe P7 launched by Xiaopeng Motors
in 2020 adopted the autonomous driving domain controller product IPU03 developed by Desay SV based on NVIDIA Xavier.
Currently, the entire industry has very optimistic expectations for the DCU market. According to Zuo Si Industry Research”s prediction,
the global shipment of DCUs (cockpit+autonomous driving) for automobiles will exceed 14 million sets by 2025, with an average annual growth rate of 50.7% from 2019 to 2025.
