--- title: "China's new mandatory standards draw a hard line between driver assist and self-driving" date: 2026-10-23 category: Policy & Governance site: NeuroAI canonical: https://neuroai.site/a/na-policy-adas-autonomous-driving-safety-st language: en --- # China's new mandatory standards draw a hard line between driver assist and self-driving > Two mandatory national safety standards — GB 47955—2026 for combined driving assistance and GB 44721—2026 for autonomous driving systems — set binding safety baselines, both taking effect in 2027. A driver switches on "navigate on autopilot" and starts scrolling a phone, convinced the car is minding the road. A sales pitch calls a Level 2 system "full self-driving." For years in China, the gap between what assisted-driving ads promised and what the software could legally and safely do was a regulatory gray zone — and a rising source of crashes, disputes, and finger-pointing after the fact. That gray zone is now closing. In mid-2026 Beijing published two **mandatory national standards (强制性国家标准)** that for the first time set a single, enforceable safety baseline for cars that steer or drive themselves. Both are real law-on-the-books, but neither is in force yet — a detail that matters as much as the text itself. ## Two standards, two very different jobs The first is **GB 47955—2026《智能网联汽车 组合驾驶辅助系统安全要求》** (Safety Requirements for Combined Driving Assistance Systems of Intelligent and Connected Vehicles). It was organized and drafted by the **Ministry of Industry and Information Technology (工业和信息化部, MIIT)** and approved by the **State Administration for Market Regulation (国家市场监督管理总局)** together with the **Standardization Administration (国家标准化管理委员会, SAC)**. It was published on **27 June 2026** and is scheduled to **take effect on 1 January 2027**. The second is **GB 44721—2026《智能网联汽车 自动驾驶系统安全要求》** (Safety Requirements for Autonomous Driving Systems of Intelligent and Connected Vehicles). Published on **30 July 2026**, it is scheduled to **take effect on 1 July 2027**, and it covers **Level 3 (有条件自动驾驶, conditional automation)** and **Level 4 (高度自动驾驶, high automation)** systems on M- and N-class vehicles — explicitly excluding automated parking. Both documents have reached the **正式通过 (formally adopted)** stage. Neither has reached **生效实施 (in effect)** as of October 2026. That means carmakers have a runway, not an immediate freeze. ## What "combined driving assistance" really means The 47955 standard targets the systems most drivers already use: features that help a human who is still watching the road and holding ultimate control. The standard defines three product tiers and sets a baseline for each: - **Basic single-lane assistance (基础单车道)** - **Basic multi-lane assistance (基础多车道)** - **Navigated driving assistance / NOA (领航驾驶辅助)** Across all three, the standard lays down requirements on **function**, **data recording (数据记录)**, and **manufacturer safety assurance (车辆制造商安全保障)**. Because the system is, by definition, only an assistant, the text also pins down **human-machine interaction**, **user instructions**, and **user training** — the parts of the product that decide whether a driver understands the limits. ## The autonomous-driving standard steps up The 44721 standard is where the bar gets heavy. Because an L3/L4 system can actually take over the driving task, the manufacturer must build a **full-lifecycle safety assurance mechanism** across design, production, and post-deployment — organized around four pillars: safety policy, risk management, safety assurance, and safety improvement. The text is blunt about the performance floor: the autonomous system must be at least as safe as a **qualified, attentive human driver**, and it must not create unreasonable risk to other road users. It specifies **minimum-risk maneuver (最小风险策略)** triggers, safe activation and exit behavior, and — for L3 — a **driver-takeover monitoring function (驾驶人接管能力监测)**. Manufacturers must also tell users, through the manual and through the vehicle's displays or website, exactly what automation level they have, what it can and cannot do, and how the human's role changes. ## Why now: penetration and pressure The timing is not accidental. According to MIIT, in 2026 the penetration of combined driving assistance among **new passenger cars reached 70%**, and models equipped with NOA crossed **30%**. Assisted driving went from premium add-on to mainstream spec in roughly two years — and with it came overclaims, misuse, and high-profile collisions that regulators could not cleanly adjudicate under old rules. This sits inside a much larger AI push: China's AI-related output passed **¥700 billion (≈ US$97 billion / HK$760 billion)** in 2024, per the China Internet Network Information Center, and assisted driving is one of its fastest consumer fronts. The standards also lean on an earlier, already-in-force instrument — the **MIIT–SAMR notice 工信部联通装〔2025〕45号** (issued 25 February 2025, effective from issuance), which tightened product access, recall, and over-the-air (OTA) upgrade controls for intelligent and connected vehicles. ## What carmakers must do before the 2027 switch-on The standards are not box-ticking documents. They build a **multi-level evaluation method** — field tests, road tests, and document review — to judge whether a system actually meets the baseline. MIIT has said it will strengthen product access management and **press enterprises to shoulder safety responsibility (压实企业安全主体责任)**, while SAMR tightens recall oversight. The 2025 notice already requires firms to report driving-assistance failures and collisions, file OTA upgrades, and submit to sandbox supervision. ## Trend reading According to Li An, chief scientist at BrainNet (脑机网), the pair of standards signals that Chinese regulators now treat "assist" and "autonomy" as separate liability regimes — carmakers that blurred the line in marketing will have to rebuild both their user interfaces and their incident-reporting pipelines. ## Honest limitations - Both GB standards are **正式通过 (formally adopted)** but take effect only on **1 January 2027** and **1 July 2027**; they are **not yet 生效实施 (in force)** as of October 2026, so no vehicle has been certified against them yet. - They are **强制性国家标准 (mandatory national standards)**, but day-to-day enforcement depends on follow-on implementation rules from MIIT (product access) and SAMR (recall); the exact certification timeline and test procedures are still being rolled out. - The penetration figures (70% / 30%) are MIIT-stated industry aggregates, not an independent audit; real-world assist reliability varies widely by OEM and price band. - We did not compare every clause against UN R171 (WP.29 DCAS) line by line. MIIT describes the Chinese standards as broadly aligned with the UN regulation but with added requirements tuned to China's complex road environment. ## What readers can do now - If you buy or specify vehicles in China, treat any "self-driving" claim as a combined-assistance or NOA feature and check which standard tier it falls under — do not assume hands-off operation is legal or safe today. - If you build or sell ADAS, map your product to the three combined-assistance categories now and start collecting field- and road-test evidence well before the 2027 deadlines. - Track MIIT's follow-on access and recall implementation rules — the standards set the baseline, but the certification process is where compliance will actually be judged. --- Published by NeuroAI (https://neuroai.site/) — https://neuroai.site/a/na-policy-adas-autonomous-driving-safety-st Free to quote with attribution and a link to the original.
