**In what aspects of assisted driving functions has the "Xiaomi HAD Enhanced Edition" been "enhanced"?**
The "Xiaomi HAD Enhanced Edition" brings significant experience upgrades in assisted driving functions across all Xiaomi EV models. For Xiaomi YU7 series, Xiaomi SU7 Ultra, and Xiaomi SU7 Pro/Max models equipped with Xiaomi HAD, after completing this Xiaomi EV OTA Winter major version update, the overall assisted driving capabilities will be aligned: longitudinal acceleration and deceleration will be smoother, lateral lane changes will be more decisive, and road condition understanding ability will be further improved.
**Firstly, based on the previous 10 million Clips version, the "Xiaomi HAD Enhanced Edition" introduces "Reinforcement Learning" and "World Model," enabling assisted driving to evolve from "knowing how to drive" to "driving well":**
- Through "Reinforcement Learning," the system repeatedly practices within the "World Model," continuously attempting and verifying under a reward mechanism to gradually form more stable, smoother, and reliable driving strategies;
- Optimized "Longitudinal Experience": In scenarios where adjacent vehicles cut in, it can predict deceleration in advance and accelerate to follow the vehicle in time, making the ride more comfortable and safe;
- Optimized "Lateral Experience": Lane changing and merging are smoother and without hesitation;
- Optimized "Road Condition Understanding Ability": At complex large intersections with multiple lanes, it can read navigation information in advance to optimize the ability to take the correct route and choose the right lane;
- Added "Defensive Deceleration in Partial Scenarios" function, including intersections without traffic lights or with malfunctioning traffic lights, and urban roads in dark/rainy environments, enhancing overall peace of mind.
**At the same time, the "Xiaomi HAD Enhanced Edition" also has multiple improvements in parking performance, such as:**
- It optimizes vehicle control capability in parking assistance scenarios, with smoother D/R gear switching and higher parking efficiency;
- Under the "Parking Assistance / Remote Parking Assistance / Spot-finding Parking Assistance" functions, it adds recognition capability for "scenarios where the door of a car next to the target parking space is open," making parking safer. However, "adjacent car door opening" remains a risky scenario; please remain vigilant at all times and control the vehicle when necessary;
- Added "Exit Assistance" function. When the vehicle is inside a parking space, clicking the "Parking Assistance" button will display the exit direction. After selecting the exit direction and confirming, the system can assist the vehicle in completing the exit;
- Added "Exterior Prompt Broadcast" function. If problems occur during remote parking assistance or closing-door parking assistance, prompts can be broadcast via the exterior speakers.

**What are "Reinforcement Learning" and "World Model"?**
"Reinforcement Learning" can be simply understood as a model training method. Previously, end-to-end training adopted "Imitation Learning." Compared to "Imitation Learning," the model can repeatedly explore in the virtual environment constructed by the "World Model" through "Reinforcement Learning" — gaining points for going right and losing points for going wrong. In this way, the model can autonomously explore and master better driving strategies, making assisted driving behavior more aligned with real road condition needs.
Therefore, the key to doing "Reinforcement Learning" well is having a high-quality "World Model." Xiaomi's "World Model" not only reconstructs the real world with high fidelity but also possesses generative expansion capabilities, capable of generating specific scenarios in digital space, supporting environments affecting assisted driving such as sunny days, rainy days, snowy days, and heavy fog, meeting diverse training needs.
**It is worth mentioning that Xiaomi's "World Model" has received full recognition from global academic authorities:**
- Xiaomi's ViSE algorithm won the Champion & Innovation awards at the 2025 ICCV RealADSim Challenge;
- Relevant papers on Xiaomi's generative models have been accepted by NeurIPS;
*ICCV is one of the three top academic conferences in computer vision globally, and NeurIPS is one of the three top academic conferences in artificial intelligence/machine learning globally, with high prestige.*

**What upgrades does Xiaomi HyperOS 1.11.0 bring to safety assistance functions?**
In terms of safety assistance functions, this update adds "Low-Speed Collision Avoidance Assist" (LAEB/RAEB) and "Emergency Steering Assist" (AES), further improving the vehicle's response capability in special scenarios.
- All Xiaomi EV models add "Low-Speed Collision Avoidance Assist" (LAEB/RAEB): When the vehicle is moving forward at low speed (1-10km/h) or reversing (1-30km/h), it can identify obstacles such as pedestrians, vehicles, and two-wheeled vehicles on the driving path. When a collision risk is judged and the driver fails to control the vehicle in time, the system will issue a warning and apply braking to avoid or mitigate collision risks.
- For models equipped with Xiaomi HAD Enhanced Edition, "Emergency Steering Assist" (AES) is newly added, enhancing Xiaomi EV's response capability in extremely complex scenarios. When encountering obstacles such as vehicles ahead, pedestrians, or two-wheeled vehicles at speeds between 80-135km/h, if the system judges that even full braking cannot reduce the degree of collision, AES emergency steering assist will perform lateral avoidance to avoid or mitigate collision risks, provided there is sufficient avoidance space and lane conditions on the side.

**What functional optimizations does this Xiaomi HyperOS 1.11.0 bring to the assisted driving functions of the Xiaomi SU7 Standard Edition?**
Xiaomi SU7 Standard Edition models equipped with Xiaomi Pilot Pro will also receive updates for parking and safety assistance functions after completing this Xiaomi EV OTA Winter major version update.
In terms of safety assistance functions, "Low-Speed Collision Avoidance Assist" (LAEB/RAEB) is newly added: When moving forward at low speed (1-10km/h) and reversing (1-30km/h), it can identify obstacles such as vehicles, pedestrians, and two-wheeled vehicles on the driving path. When a collision risk appears, the system will issue a warning and apply braking.
Parking assistance also has multiple improvements, such as:
- It optimizes vehicle control capability in parking assistance scenarios, with smoother D/R gear switching and higher parking efficiency;
- Under the "Parking Assistance / Remote Parking Assistance / Spot-finding Parking Assistance" functions, it adds recognition capability for "scenarios where the door of a car next to the target parking space is open," making parking safer. However, "adjacent car door opening" remains a risky scenario; please remain vigilant at all times and control the vehicle when necessary;
- Added "Exit Assistance" function. When the vehicle is inside a parking space, clicking the "Parking Assistance" button will display the exit direction. After selecting the exit direction and confirming, the system can assist the vehicle in completing the exit;
- Added "Exterior Prompt Broadcast" function. If problems occur during remote parking assistance or closing-door parking assistance, prompts can be broadcast via the exterior speakers.

**Does Xiaomi EV's AES "Emergency Steering Assist" function work in manual driving or assisted driving mode?**
Xiaomi EV's AES "Emergency Steering Assist" function works normally in both manual driving mode and assisted driving mode. After this Xiaomi EV OTA Winter major version Xiaomi Hyper 1.11.0, models equipped with "Xiaomi HAD Enhanced Edition" have newly added AES "Emergency Steering Assist" function, enhancing Xiaomi EV's response capability in extremely complex scenarios. Here, we kindly remind you:
- After OTA upgrading to Xiaomi HyperOS 1.11.0, the AES "Emergency Steering Assist" function is turned off by default. You need to manually enable this function in the vehicle machine. During subsequent use, this function will maintain its working state (on or off) according to memory until you manually change the function status next time, requiring no repeated operations.
- When using assisted driving functions, if such high-risk scenarios requiring emergency avoidance occur, the system will actively exit assisted driving once AES works normally and takes effect. Because such extreme scenarios far exceed the scope of assisted driving capabilities, they belong to necessary driver manual control scenarios.
We need to remind you that AES "Emergency Steering Assist" function is an advanced safety assistance function for extreme scenarios. Xiaomi EV has conducted very strict design and verification for its trigger conditions and action strategies. Xiaomi EV adheres to the principle of "Brake rather than swerve, stability first" in its safety philosophy:
- When the system believes there is a possibility of fully decelerating and mitigating the degree of collision through forward collision avoidance assist, it will still adopt the emergency braking strategy;
- Only when severe collision will still occur despite full braking will the system employ emergency evasion strategies under permissible conditions.
Therefore, we seriously remind all owners and prospective owners that assisted driving functions are not omnipotent, and driving still requires maintaining focus and paying attention to road condition information at all times. *c*
