1. New Working Groups Established

On 10 April 2026, China Automotive Technology and Research Center (CATARC) convened a kick-off meeting for two new standardization working groups: Automotive Software Working Group and Automotive Data Working Group. Each group will specialize in formulating standards within their respective domains.

1. Internal Technical Review of 3 Automotive Product Carbon Footprint Standards

On 10 April 2026, SAC/TC114/SC27(Electric Vehicles) and SAC/TC548(Carbon Management) jointly convened an review meeting for 3 national standards on carbon footprint quantification for electric vehicle. All 3 standards passed the review and are now awaiting submission of formal draft for approval by the relevant national authorities:

1. 20243770-T-339 Greenhouse gases — Quantification methods and requirements for carbon footprint of products — Electric vehicles

2. 20243775-T-339 Greenhouse Gases — Quantification methods and requirements for carbon footprint of products — Traction batteries used in electric vehicles

3. 20243773-T-339 Greenhouse Gases – Quantification methods and requirements for carbon footprint of products – Driving motors used in electric vehicles

These standards establish the methodological basis for calculating product carbon footprints across the full life cycle, covering quantification purposes, scope, inventory analysis, impact assessment, result interpretation, and reporting for electric vehicles, power batteries, and drive motors.

• Internal Technical Review of Electric Vehicles Standards

From 8 to 9 April 2026, the 2026 Second Standards Review Meeting of the SAC/TC114/SC27(Electric Vehicles) was held, attended by over 70 experts from the subcommittee members, observers, and standard drafting units.

The meeting approved 15 project proposals in the fields of electric vehicles, power batteries, fuel cells, and charging and swapping, as well as the review proposals for 5 standards.

It also reviewed and passed the following:

1. 20250835-T-339Solid-state battery for electric vehicle—Part 1: Terms and classification and other 7 voluntary national standards,
2. 2025-0545T-QCTechnical Requirements for Interchangeability of Pure Electric Commercial Vehicle Chassis-Based Onboard Battery Swapping Systems (sector standard)

3. 20256717-Z-339 Technical specifications for solid electrolyte for solid-state battery for electric vehicle,

4. and the foreign language version of GB 18384-2025 Electric vehicles safety requirements (mandatory)

1. SAC/TC114 2026 Standardization Work Items

In March 2026, 2 voluntary ICV automotive standards were were published

1. GB/T 47351-2026 Intelligent and connected vehicles—Technical requirements and test methods of vehicle-control operating system (Effective date: 2026-07-01)

2. GB/T 47341-2026 Intelligent and connected vehicles—Technical requirements and test methods of vehicle-info operating system (Effective date: 2026-07-01)

In addition, 3 mandatory standards projects were launched:

1. 20261955-Q-339 Post crash safety requirement for electric vehicle

2. 20261956-Q-339 Intelligent and connected vehicle — Safety requirements for parking combined driving assistance system

3. 20261957-Q-339 Requirements for vehicle data security

1. Autonomous Driving (SAC/TC114/SC34)

From 30 March to 3 April 2026, SAC/TC114/SC34 (Intelligent and Connected Vehicle) held the 17^th working meeting, bringing together over 130 experts to discuss 13 standards at various stages of development.

Among them, there are 3 mandatory standards:

1. 20256778-Q-339 Intelligent and connected vehicle – Safety requirements for automated driving system (Call for Comment)
2. 20253094-Q-339Technical requirements and testing methods for advanced emergency braking system of heavy-duty vehicles (Call for Comment)
3. Intelligent and connected vehicles– Safety requirements for automated parking system (Waiting for official adoption of the standards project)

5 voluntary standards and 1 national standardization technical guiding document:

4. GB/T 41798-2022Intelligent and connected vehicle—Simulation test methods and requirements for automated driving function
5. GB/T 44719-2024Intelligent and connected vehicle—Methods and requirements of road test for automated driving functions
6. 20260284-T-339 Road vehicles — Controller area network (CAN) — Part 1: Data link layer and physical coding sublayer (Call for Comment)
7. 20250898-T-339Technical requirements and test methods for on-board positioning system—Part 2: Inertial navigation (Call for Comment)
8. Technical requirements and testing methods for lane keeping assist system of light-duty vehicles (GB/T project waiting for official adoption)
9. 20262002-Z-339Intelligent and connected vehicle — Simulation engineering for driving automation system — Part 3: Credibility assessment method for simulation testing (technical document, GB/Z)

Notably, 5 standards with no public information on their status were discussed, suggesting they may be in the internal project proposal phase:

10. Road vehicles– Test scenarios for automated driving systems – Classification for application scenarios
11. Road vehicles– Test scenarios for automated driving systems – Scene evaluation and test case generation
12. Intelligent and connected vehicle — Simulation engineering for driving automation system — Part 4: Requirements and methods for implementation of simulation tests
13. Vehicle software identification code
14. Intelligent and connected vehicles – Simulation engineering of driving automation systems
