Ministry of Industry and Information Technology solicits opinions on relevant standards for intelligent connected vehicle combination driving assistance
Recently, the Ministry of Industry and Information Technology (hereinafter referred to as the "Ministry of Industry and Information Technology") issued a draft for soliciting opinions on the "Technical Requirements and Test Methods of Intelligent Connected Vehicle Combined Driving Assistance System" and solicited opinions from the public. This move marks a step further in the standardization of intelligent connected vehicles in my country, aiming to standardize industry technology development and improve the safety and reliability of driving assistance systems.
With the rapid development of intelligent connected vehicles, Combined Driving Assistance System (CDAS) has become the focus of industry attention. The system combines multiple sensors and algorithms to achieve lane keeping, adaptive cruise, automatic emergency braking and other functions, greatly improving driving safety and comfort. However, due to the lack of unified technical standards, the system performance of various manufacturers is uneven, and it is urgent to promote the healthy development of the industry through standardized means.
1. Main contents of the draft for soliciting opinions
The draft for soliciting opinions issued by the Ministry of Industry and Information Technology mainly revolves around the technical requirements, test methods and evaluation indicators of the intelligent connected vehicle combination driving assistance system, including the following contents:
| project | Technical requirements | Test Methods |
|---|---|---|
| Lane Keeping Assist | The system should maintain the lane center line stably when the vehicle speed is ≥60km/h, with a lateral offset of ≤0.3m | Conduct straight line and curve working conditions tests on standard test roads |
| Adaptive cruise control | The following distance is adjustable, the minimum following distance is ≥1s, acceleration and deceleration smoothness ≤0.3m/s² | Use the target car simulator to test the following performance at different speeds |
| Automatic emergency braking | The identification distance for stationary vehicles is ≥100m, and the braking deceleration is ≥6m/s² | Multi-scene test using standard test dummies and vehicles |
| Human-computer interaction interface | The system status display is clear, and the warning signal response time is ≤0.5s | Evaluate interface friendliness through driver simulation test |
2. Industry response and expert opinions
After the draft for soliciting opinions was released, it attracted widespread attention from the industry. Many car companies said they will actively participate in standard formulation and promote technological upgrades. Industry experts believe that the introduction of unified standards will help solve the following problems existing in the current intelligent driving assistance system:
1. Confused functional naming: Each manufacturer uses different names for similar functions, which can easily lead to misunderstandings from consumers;
2. Large performance differences: some systems perform unstable in complex scenarios and pose safety hazards;
3. Inconsistent testing methods: the lack of comparable test data affects consumer purchasing decisions.
Experts from the China Automobile Engineering Society pointed out: "This standard solicitation of opinions reflects the principle of 'safety first', especially clear requirements for system failure protection and redundant design, which will significantly improve the overall safety level of the industry."
3. Comparison of domestic and foreign standards
my country's intelligent connected vehicle standards are in line with the international level, and some indicators are more stringent. The following table compares the main technical standards at home and abroad:
| Standard items | China's draft for soliciting opinions | EU ECE R157 | SAE J3016, USA |
|---|---|---|---|
| Applicable Level | Level L2 and below | Level 3 or below | L1-L5 full-level |
| Minimum distance to follow the car | ≥1.0s | ≥0.8s | No mandatory requirements |
| Emergency braking test scenario | 12 kinds | 8 kinds | 10 kinds |
| System response delay | ≤100ms | ≤150ms | ≤200ms |
4. Impact on industrial development
This standard solicitation of opinions will have a profound impact on the intelligent connected vehicle industry:
1.Technical threshold increased: Some companies with weak R&D capabilities may face elimination, and the industry concentration will increase;
2.Test and certification demand increases: Third-party testing institutions will usher in development opportunities;
3.Supply chain reshaping: The status of a core component supplier for high-performance sensors, chips and other core components will be further consolidated;
4.Increased consumer confidence: Unified standards help eliminate users’ doubts about the safety of smart driving.
According to industry forecasts, by 2025, the market size of my country's combined driving assistance system is expected to exceed 100 billion yuan, and the promotion of standardization will lay the foundation for the healthy development of this market.
5. Follow-up work arrangements
According to the work deployment of the Ministry of Industry and Information Technology, the standard solicitation of opinions will continue until the end of December 2023. Next, the Ministry of Industry and Information Technology will:
1. Organize industry experts to organize and analyze feedback;
2. Carry out supplementary test verification work;
3. Hold a standard review meeting in a timely manner;
4. It is planned to release formal standards in the first half of 2024.
All sectors of the intelligent connected vehicle industry can submit opinions and suggestions through the official website of the Ministry of Industry and Information Technology to jointly promote the construction of my country's intelligent connected vehicle standard system.
