Xiaomi recalls 110,000 SU7 vehicles via OTA, and the strictest intelligent driving regulations are about to be released.

On the morning of September 19th, Xiaomi Automobile filed a record with the State Administration for Market Regulation and announced the recall of 110,000 standard - version SU7 models. The safety hazards in the L2 high - speed pilot assisted driving function will be resolved through OTA upgrades.

The recall notice mentioned that in some vehicles within the scope of this recall, under certain circumstances when the L2 high - speed pilot assisted driving function is enabled, the recognition, early warning, or handling of extremely special scenarios may be insufficient. If the driver does not intervene in time, it may increase the risk of collision, posing a safety hazard.

Xiaomi's recall this time follows the "Notice on Further Strengthening the Management of Product Access, Recall, and Software Online Upgrades of Intelligent Connected Vehicles" issued by the Ministry of Industry and Information Technology and the State Administration for Market Regulation on February 25th, 2025. The notice clearly requires that when automobile enterprises eliminate product defects through OTA upgrades, they should implement them in accordance with the "Measures for the Implementation of the Regulations on the Recall of Defective Automobile Products".

Similar record - based recall methods have been used by automobile enterprises such as Tesla and BYD before.

The core of the major autumn OTA update for the SU7 launched by Xiaomi this time lies in enhancing the safety and user experience of assisted driving. The main updates include:

Optimize large - vehicle avoidance and detouring: Identify large vehicles crossing the lane line earlier, complete the in - lane deviation in advance to reduce the sense of oppression; detour more flexibly and safely.

Add "Dynamic vehicle speed": Automatically adjust the target speed of the assisted driving system in complex environments (such as rainy days and at night), which is enabled by default.

Optimize the speed control strategy: Dynamically adjust the target speed in combination with the road and traffic environment.

Add "Mistaken acceleration suppression assistance (MAI)": Reduce the risk of accidentally stepping on the accelerator.

Optimize DMS driver monitoring: Cancel the repeated pop - up prompts during the "DMS" journey.

It can be seen that this update is directly aimed at improving safety, and some functions are also in line with the mandatory national standard "Safety Requirements for Combined Driving Assistance Systems of Intelligent Connected Vehicles" which is currently seeking public comments.

From January to July 2025, the sales volume of new domestic vehicles equipped with combined driving assistance systems reached 7.7599 million, a year - on - year increase of 21.31%. The penetration rate rose to 62.58%, an increase of 6.5 percentage points compared with last year. Now, more than 60% of new vehicles are equipped with driving assistance functions.

In the current highly competitive market, automobile enterprises are attracting consumers with promotional slogans such as "High - level intelligent driving", "Zero takeover", and "Drive anywhere there is a road". However, consumers often have difficulty distinguishing the boundary between driving assistance and autonomous driving, and tend to downplay the limitations of the system, leading to dangerous behaviors such as the driver taking hands off the steering wheel and being distracted, which may cause accidents.

Although China has issued a number of standards for intelligent connected vehicles before, there is still a gap in the mandatory safety specifications for driving assistance systems, resulting in the lack of a unified technical basis for product access, quality supervision, and post - event traceability and accountability.

The "Safety Requirements for Combined Driving Assistance Systems of Intelligent Connected Vehicles" for which the Ministry of Industry and Information Technology is seeking public comments recently is expected to fill this gap.

The entire draft for public comments is very detailed. It clearly stipulates the safety requirements for different types of assisted driving systems, the methods of on - site and road tests, and the methods of user notification. Dongchehui has extracted some content that you may be interested in.

Multi - level evaluation system

Classify the systems into three categories: basic single - lane (high - speed LCC, ACC, lane keeping), basic multi - lane (automatic lane change with turn signal on at high speed), and pilot combined driving (NOA, parking space to parking space), and set safety requirements for each category respectively.

The tests cover on - site, road, and document inspections, with a total of 46 scenarios, and fault injection and interference tests are introduced.

If the vehicle supports night - time assisted driving, a night - time road test is required.

Mandatory installation of "black box"

Vehicles must be installed with a combined driving assistance data recording system to record collision events, driver operations, sensor status, etc.

Storage capacity requirements: Type I ≥ 2500 events, Type II ≥ 8 hours of continuous data.

The data must support judicial evidence collection, taking into account privacy and network security.

Strengthen driver monitoring

Prompt when the hands are off the steering wheel for 5 seconds, and upgrade the prompt after 10 seconds.

Prompt when the line of sight is off for 5 seconds, upgrade after 3 seconds, and require mandatory takeover within 5 seconds after the upgrade.

If the driver is off the required state multiple times, the system should be disabled for at least 30 minutes.

Currently, the industry generally believes that the requirements of the new standard are very strict. The simulation models that automobile enterprises highly recommended in the past are required to clarify the correlation between simulation and the real entity. After safety verification, simulation, and on - site tests, the development cycle is expected to be extended by nearly half a year.

The mandatory data recording system makes it possible to trace the responsibility for accidents, and it is difficult for automobile enterprises to easily exempt themselves from liability by claiming user misoperation.

In the short term, the introduction of this new regulation will inevitably lead to a round of integration and reshuffle among automobile enterprises and assisted driving suppliers. After the development cycle is extended, the software of the assisted driving system may become more expensive in the short term, and the launch of new functions will also slow down.

But in the long run, a safer and more reliable assisted driving system is beneficial to the entire travel industry.
