The Ministry of Industry and Information Technology (MIIT) has released the draft of a mandatory national standard titled “Safety Requirements for Combined Driving Assistance Systems in Intelligent Connected Vehicles.” Public opinions are now being solicited.
This standard aims to fill the current gap in baseline safety requirements for combined driving assistance systems, providing key technical references for:
- Industry access
- Quality supervision
- Post-event traceability
Alignment with Global Standards
The MIIT, following the principle of “urgent use first,” tasked the National Automotive Standardization Technical Committee to develop the new standard.
- The framework aligns with UN Regulation No. 171 (“Uniform Provisions Concerning the Approval of Driver Assistance Systems for Vehicles”).
- It also takes into account China’s complex road conditions, product diversity, and multiple technological approaches.
Categories of Combined Driving Assistance Systems
The standard defines four categories of systems:
- Basic Single-Lane Systems
- Basic Multi-Lane Systems
- Pilot-Assisted Systems
- Parking Systems
These fall under a triple-layered safety framework focusing on:
- Enhancing product performance
- Strengthening safety guarantees
- Standardizing system usage
Key Safety Requirements
The standard imposes strict rules on Operational Design Conditions (ODC), ensuring systems only operate within defined boundaries.
For different functionalities (single-lane, multi-lane, pilot assistance), the standard specifies requirements covering:
- Human-machine interaction
- Functional safety and expected functional safety
- Cybersecurity
- Data recording
A multi-layered validation plan is also introduced, including:
- Site testing
- Road testing
- Documentation review
Lifecycle Safety Assurance
The standard proposes a comprehensive lifecycle safety assurance methodology to address risks across all phases:
- Development phase: Reinforced safety-related risk design
- Production phase: Stronger manufacturing robustness and traceability
- Usage phase: Ongoing system validation and monitoring
Both hardware and software security measures are mandated at every stage of the lifecycle.
