Xiaomi SU7 Boosts AEB, Fixes Steering Detection
💡SU7's AEB object expansion + torque detection key for automotive CV/ADAS builders.
⚡ 30-Second TL;DR
What Changed
AEB now detects vehicles, pedestrians, two-wheelers, barriers, barrels, boxes, stones, tires at 20-135km/h forward
Why It Matters
Enhances edge-case safety but exposes ADAS hardware trade-offs, influencing EV design choices.
What To Do Next
Test torque and expanded object detection in your ADAS computer vision pipelines.

🔑 Enhanced Key Takeaways
- •The AEB update is part of Xiaomi's broader 'Xiaomi Pilot' software push, which leverages the NVIDIA Orin-X platform to process increased sensor fusion data for non-standard obstacle recognition.
- •The steering wheel detection issue stems from the physical material properties of the optional carbon fiber trim, which interferes with the capacitive touch sensors standard in the base model's leather-wrapped steering wheel.
- •Xiaomi has implemented a 'driver monitoring system' (DMS) camera-based fallback to verify driver attentiveness when the steering wheel torque sensor provides ambiguous data, reducing the frequency of false-positive warnings.
📊 Competitor Analysis▸ Show
| Feature | Xiaomi SU7 (Updated) | Tesla Model 3 (HW4) | XPeng P7i |
|---|---|---|---|
| AEB Obstacle Range | High (incl. debris) | High (Vision-only) | High (LiDAR-assisted) |
| Steering Detection | Torque/Capacitive Hybrid | Vision/Torque Hybrid | Capacitive |
| Pricing (CNY) | 215,900+ | 231,900+ | 223,900+ |
🛠️ Technical Deep Dive
- AEB System Architecture: Utilizes a multi-sensor fusion approach combining 128-line LiDAR, millimeter-wave radar, and 8MP high-definition cameras.
- Obstacle Recognition Logic: Employs a deep learning-based 'General Obstacle Detection' (GOD) network capable of identifying irregular shapes (e.g., traffic cones, fallen tires) not present in standard training datasets.
- Steering Detection Mechanism: The system utilizes a dual-input validation method: a capacitive sensor layer (in standard wheels) and a steering column torque sensor (for all wheels) to detect micro-adjustments in steering input.
🔮 Future ImplicationsAI analysis grounded in cited sources
Xiaomi will transition to vision-only AEB for future models.
The integration of advanced GOD networks suggests a strategic shift toward reducing reliance on expensive LiDAR for standard safety features.
Carbon fiber steering wheel options will be phased out or redesigned.
The inherent difficulty in integrating capacitive sensors into carbon fiber materials creates a persistent user experience gap compared to standard trims.
