Black Sesame Smart Unveils FAD Tianyan L3 Autonomous Driving System Based on FAD 2.0 Platform

On April 24, 2026, Black Sesame Technologies officially unveiled its FAD Tianyan L3 autonomous driving platform at the 2026 Beijing Auto Show. Built upon the FAD 2.0 open platform launched earlier this year, this new platform marks the concrete implementation of the FAD 2.0 framework and accelerates the large-scale adoption of the Huashan A2000 family of chips. The FAD 2.0 open platform integrates the high-performance computing platform based on the Huashan A2000 chip family, a comprehensive software SDK, the ShanhAI AI toolchain, end-to-end/VLA reference models, and third-party algorithm models. Positioned as a near-production-ready, full-scenario general-purpose intelligent driving open platform, it aims to support broad industry deployment. The FAD Tianyan platform features a dual-chip design using the Huashan A2000U, with each A2000U delivering 700 TOPS of equivalent computing power. Powered by Black Sesame’s proprietary Jiushao NPU architecture, it supports hardware-accelerated Transformer inference and mixed-precision computation. The two chips are interconnected via high-speed links to enable low-latency, high-bandwidth data collaboration and mutual redundancy, allowing a single-domain controller to meet ASIL-D functional safety requirements. In terms of software architecture, the platform implements a multi-layered isolation and safety framework. When isolation is enabled, the MCU achieves physical-level separation from the SoC in both power supply and internal bus, enabling it to operate as an independent external MCU—thereby reducing the risk of hardware common-cause failures. The cybersecurity subsystem complies with ISO/SAE 21434 standards and incorporates China’s national cryptographic algorithms, secure boot mechanisms, and root certificate management. The functional safety subsystem is Black Sesame’s self-developed ASIL-D-grade system, equipped with a dedicated chip safety library for the A2000 family that enables hardware and software fault detection and recovery. Meanwhile, the SoC subsystem runs an ASIL-B-compliant Linux OS, balancing robust safety assurance with ecosystem compatibility. The platform is pre-engineered to align with China’s upcoming mandatory national standard “Safety Requirements for Automated Driving Systems in Intelligent Connected Vehicles,” scheduled to take effect on July 1, 2027. It employs heterogeneous algorithms and dual-redundancy mechanisms: perception, planning, and control modules all deploy either dual-redundant or heterogeneous algorithms, with real-time cross-verification to enhance decision-making robustness. The overall architecture further includes redundant power supplies, multiple sets of sensor redundancy, a strongly isolated MCU, and layered software isolation mechanisms—forming a hybrid safety foundation that combines ASIL-D firmware with an ASIL-B Linux system. Chip-to-chip interconnectivity also enables scalable computing power to support a high-performance L3 autonomous driving experience. With the launch of the FAD Tianyan platform, Black Sesame Technologies will further empower industry partners to accelerate the mass production and deployment of L3 autonomous driving systems, driving intelligent transformation across the entire automotive value chain.
