Great Wall Motors Integrates Ambarella CV25AQ AI Vision SoC in New WEY Mocha SUV

At the Shanghai Auto Show, Ambarella announced that Great Wall Motors’ new WEY Mocha flagship SUV incorporates a camera‑based in‑cabin sensing system built around the Ambarella CV25AQ CVflow AI vision processor.

The system is integral to GWM’s Coffee Intelligence platform, first launched in 2020, which advances automotive technology through intelligent cockpit, drive, and electrical architecture solutions.

Senya Pertsel, senior director of automotive marketing at Ambarella, told embedded.com that the in‑cabin data from CV25AQ feeds into Coffee Intelligence to support autonomous driving.

The CV25AQ‑based system supports multiple simultaneous multi‑camera channel combinations for recording and in‑cabin sensing, meeting Euro NCAP 2025 standards. It delivers reliable visual processing in complex lighting and is a key component of GWM’s intelligent drive chain.

Fermi Wang, CEO of Ambarella, said, “Ambarella and GWM have a long history of successful collaboration, with several generations of vision systems already in production across many models. Together we have refined this new CVflow‑based multi‑channel AI vision system.”

The AEC‑Q100 qualified CV25AQ SoC integrates image processing, 6MP30 video encoding/decoding, and CVflow computer‑vision processing in a single low‑power package. Built on advanced 10 nm technology, it delivers low power consumption and high performance for both human‑vision and computer‑vision tasks, making it ideal for multi‑channel DVRs, electronic mirrors with recording, and driver/in‑cabin monitoring.

CVflow enables 6 MP resolution computer‑vision at long ranges with high accuracy, supports AVC and HEVC encoding at low bit‑rates, and its ISP provides excellent low‑light imaging and HDR detail extraction.

Security features include secure boot with TrustZone, secure memory, TRNG, OTP, DRAM scrambling, virtualization, and per‑interface secure levels. Ambarella’s SDK offers a full set of tools for customers to port their own neural networks onto the SoC.

The automotive market remains a key target for Ambarella’s CV SoC lineup. In its latest earnings report, CEO Fermi Wang noted that by the end of April 2021, the company had shipped 300 000 CV SoCs to automotive customers and expects cumulative shipments of 2 million, with automotive revenue accounting for 15–20 % of total FY 2021 revenue. He added that automotive revenue should rise at least 20 % in Q1 2022.

GWM’s Coffee Intelligence platform runs on Qualcomm’s Snapdragon Ride, supporting multiple high‑resolution cameras and offering L2+ and L3 intelligent‑driving capabilities with heterogeneous sensors. Paired with upgraded computing platforms, the system delivers over 700 TOPS, providing redundancy and the horsepower required for L4/L5 and full‑scenario autonomous driving.
