Next-gen AI SoCs for fleet dash cams and vehicle gateways

Ambarella, Inc. has announced its latest AI SoCs generation for in-vehicle fleet telematics systems. Ideal for AI dash cams integrating front-facing ADAS and DMS, the new CV75AX provides up to 2x the AI performance over its prior-generation SoC, allowing the latest transformer neural networks for improved accuracy and reduced false positives without having to train for every object. The new device also provides AI horsepower for more complex driver-scoring models. Ideal for next-gen vehicle gateways, the new device supports up to ten cameras and offers up to 6x the AI performance over its predecessor, enabling both vision transformers and multi-modal vision language models (VLMs), which supply instant event alerts and multi-channel video pre-categorisation and natural-language searches for more efficient video analysis – all without the need for training.

"Our current generation of AI SoCs has been widely adopted for in-vehicle systems by leading fleet telematics providers, with our unique ability to enable fanless AI dash cams that don't impede the driver's view," said Senya Pertsel, sr director of automotive marketing at Ambarella. "With our new CV75AX and CV72AX SoCs' increased AI performance, efficiency and features while maintaining that fanless capability, we have already secured designs and are being evaluated by leading telematics providers for next-generation systems to enable transformer-perception, VLM-analysis and driver-scoring models."

These new fleet telematics SoCs feature the company's latest CVflow 3.0 AI engine, 2x the CPU performance, LPDDR5 support with 2x the DRAM bandwidth and a higher-speed USB 3.2 interface for 5G modems compared to the prior generation. They also integrate the latest generation of its industry-leading image signal processor and H.264/5 video encoder, delivering high image quality for human viewing and computer vision and multi-channel recording for evidence collection. Further, these are the latest company SoCs to be manufactured in Samsung Foundry's 5nm FinFET process technology, allowing them to operate over a wide temperature range (-40C to 105C ambient), which is critical for automotive applications and further contributing to their lower power consumption and increased performance compared to the prior generation.

With their increased AI performance, these new SoCs also bring the company's advanced AI-based HDR image processing technology to in-vehicle fleet telematics systems. Known as Vivid HDR, this proprietary technology utilises AI to augment and improve the image quality in scenes with widely contrasting light and dark areas.

The CV75AX's on-chip MCU core has a new ultra-low-power sleep mode where the SoC consumes less than 5mw. This eradicates an external MCU's need to monitor the parked vehicle's sensors without battery depletion, reducing BOM cost and design complexity.

The devices use the same SDK and are supported by Ambarella's Cooper Developer Platform to accelerate the development of in-vehicle fleet telematics applications.
