Desay SV Brings Single-Chip Cockpit-Driving Integration to Chery Fengyun T7

Zoss Automotive Research forecasts China's cockpit-driving integration market will grow at a 36 percent compound annual rate from 2026 to 2030, with 3.6 times more growth space by 2030, the report said. As cockpit and ADAS systems share one chip, limited compute has increasingly tilted toward ADAS, causing lagging infotainment, dropped SR frames, and delayed cockpit responses in some solutions. The challenge is to preserve ADAS safety and capability while giving the cockpit enough resources.

The report described two routes. One uses multiple suppliers for sensors, chips, domain controllers, cockpit software, and ADAS algorithms. With different underlying logic, assembled solutions can overdevelop ADAS under limited compute, raising risks of lag, SR frame drops, and ADAS downgrades. Interfaces, software versions, algorithms, and base systems must be aligned continuously; failures often cross modules and are hard for one supplier to solve, increasing joint debugging costs. The other route is full-stack integration, where one supplier combines hardware, base software, cockpit, and ADAS in one system, allowing it to manage chip and vehicle computing resources, locate problems faster, and control delivery.

Desay SV, described as a leading full-stack integrator, defines its product as 'one chip, dual intelligence; cockpit and driving both optimized.' It says common development of underlying algorithms and upper-layer applications has opened a single-chip memory architecture. The company requires cockpit performance not to fall below the mainstream experience of Qualcomm's SA8155P, a 7-nanometer cockpit SoC that performs 8 trillion operations per second and supports up to six cameras. Desay SV's third-generation cockpit used the SA8155P and has been deployed in Li Auto and Chery vehicles. It then allocates remaining compute to ADAS, reserving resources for perception, decision-making, and safety redundancy.

In October 2024, Desay SV launched the ICP S01E native cockpit-driving integration architecture. In August, Chery's Fengyun T7 began pre-sales with the solution, marking volume production. The SA8775P-based system brings cockpit-driving integration to the 100,000 yuan market, where hardware costs must be compressed without weakening ADAS or cockpit experience. In complex intersections, congestion, or parking, ADAS loads rise, but the cockpit's designated resource boundaries are not invaded, the report said. The key is designing cockpit and ADAS as one whole. Desay SV's common-origin, synchronized approach keeps algorithms and applications consistent, so ADAS data is presented in the cockpit through the same data link. The ICP S01E architecture reorganizes data flows from the bottom according to single-chip logic. Through compute-storage integration and memory sharing, it cuts latency by more than 90 percent and enables microsecond-level inter-core communication. In one example, when a highway-pilot vehicle merges from a ramp and a truck cuts in, the cockpit renders rear vehicle conditions while ADAS decides whether to accelerate or yield, making the decision closer to an experienced driver.

Desay SV is one of few full-stack suppliers covering sensors, domain controllers, ADAS algorithms, and cockpit software, with self-developed algorithm toolchains and cross-platform adaptation. The ICP S01E architecture can combine with 4D millimeter-wave radar, bringing front-end perception, domain computing, and ADAS algorithms into one development system. This reduces cross-vendor interface adaptation and joint debugging for different models and markets. Public information shows the related solution has won overseas project nominations.

For automakers, the report said the single-chip solution cuts costs, improves efficiency, and supports overseas expansion. Reuse of single-chip compute and a simplified physical architecture reduce domain controller and wiring harness costs, bringing 300,000 yuan-class cockpit and ADAS coordination to the 100,000-150,000 yuan mainstream market. Industry data cited in the report shows a single chip for cockpit-driving fusion can cut hardware costs by 1,500 to 4,000 yuan per vehicle and shorten R&D and delivery cycles by 56 percent. It also cited data showing about 165 all-new models launched in China in the first half of 2026, one every 26 hours. Desay SV says the ICP S01E platform includes European regulatory adaptation and export compliance standards. It has won new global project nominations from multiple foreign brands, with some overseas automaker projects moving toward mass production.

For users, the report cited Taibo Think Tank data showing the core demand is consistency of system interaction. Drivers care whether cockpit functions remain smooth after ADAS is activated, whether multiple systems run stably, and whether problems are reported and resolved promptly. Desay SV includes a one-click feedback function. If automatic parking is blocked and a door cannot open, a user can click the button; the system obtains a time-aligned panoramic snapshot and packages exterior camera images, ADAS decision routes, and cockpit operation logs to a cloud-based brain for algorithm optimization. Under the integrated architecture, ADAS and cockpit logs can be aligned by a unified timestamp and analyzed on the same timeline.

The report said cockpit-driving integration is shifting automotive intelligence competition from stacked features to system efficiency. As chip platforms standardize, differentiation in single modules narrows, and suppliers must take responsibility for larger system boundaries. Future suppliers must handle hardware, software, data, and compute, and be accountable for system stability and iteration efficiency. Desay SV's bet on full-stack integration is described as preparation for that change. In the next Tier 1 competition, stronger components will no longer be decisive; the ability to absorb more system complexity will determine who gains entry.

Editor's Summary

Leiphone reported that Desay SV's SA8775P-based cockpit-driving integration solution has entered volume deployment with Chery Fengyun T7, targeting the 100,000 yuan segment. The report presents full-stack integration as a way to balance cockpit and ADAS resources while cutting hardware costs, shortening delivery cycles, and supporting overseas compliance. It also notes competition from multi-vendor approaches and the challenge of managing greater system complexity.
