GB 47955—2026, China's first mandatory standard for L2 combined driver-assistance systems, takes effect on January 1, 2027. BYD secures early organizational certification as the industry shifts from feature races to safety compliance.
Mandatory Standard Sets New Safety Baseline
China's first mandatory national standard for Level 2 combined driver-assistance systems — GB 47955—2026 — has been approved and will take effect on January 1, 2027. Officially announced by the Ministry of Industry and Information Technology on July 2, 2026, the standard was drafted with participation from BYD, Xiaomi, Tesla, NIO, XPENG, and Li Auto. The standard establishes compulsory safety requirements for three core scenarios: basic single-lane assistance, basic multi-lane assistance, and navigation-assisted driving. It covers system functions, data recording, driver monitoring, human-machine interaction, user information, and manufacturer safety responsibilities. Key figures:
- Standard code: GB 47955—2026
- Effective date: January 1, 2027
- L2 feature penetration in new passenger vehicles: 70%
- NOA-equipped models penetration: over 30%
BYD Secures Early Organizational Certification
BYD obtained its combined driver-assistance safety-management system certificate on July 28, 2026, becoming one of the first automakers to pass the organizational-level assessment. The certification evaluates processes at the vehicle-manufacturer level, including product development, production controls, and safety validation. Important distinction: this is an organizational certification, not blanket product approval for every God's Eye-equipped vehicle. BYD stated that all models with its intelligent driving system exceed the new minimum requirements, yet individual vehicle configurations and subsequent OTA updates will still require separate approval. Drafting-group participants include:
- BYD — safety management framework
- Xiaomi — human-machine interaction
- Tesla — data recording
- NIO, XPENG, Li Auto — scenario validation and test methods
| Dimension | Core Requirement | International Alignment |
|---|---|---|
| System functions | Single-lane / multi-lane / nav-assisted | Coordinated with UN R171 |
| Data recording | Operational data retention and traceability | Added China-specific scenarios |
| Driver monitoring | Mandatory DMS deployment, attention detection | Exceeds European baseline |
| HMI | Clear distinction between assistance and automation | Strengthened user-obligation rules |
Compliance Pressure and Industry Impact
The new standard imposes rigid constraints on manufacturers' safety-management processes. Automakers have less than six months to complete comprehensive adjustments to product development, production controls, and user-communication systems. Primary implications:
- DMS becomes de-facto mandatory: All vehicles offering advanced assistance must deploy effective driver-monitoring systems
- OTA updates remain regulated: Even with organizational certification, individual function updates require independent approval
- Driver responsibility reinforced: The standard mandates that drivers must continuously monitor traffic and remain ultimately responsible
EX1000.COM notes that China's intelligent-driving market is transitioning from "feature competition" to "safety-compliance competition." For Chinese automakers exporting to Central Asia, Russia, and other markets, the domestic standard upgrade will simultaneously raise the safety baseline of their overseas products — a critical step in building global trust.
Outlook: Global ADAS Regulation Convergence Accelerates
GB 47955—2026's core provisions are coordinated with UN R171 and other international regulations, while adding test scenarios reflecting China's complex traffic conditions. This signals a shift from "following international standards" to "contributing Chinese experience." For overseas buyers, especially in Central Asia and Russia, choosing Chinese-brand vehicles that meet China's latest mandatory safety standards means receiving safety assurance aligned with — or exceeding — international benchmarks.
