Xiaomi Investigates SU7 Ultra Parking Bug
💡A real-world parking failure shows why autonomous-driving teams need stronger corner-case testing and rapid feedback loo
⚡ 30-Second TL;DR
What Changed
The SU7 Ultra’s automated parking failed repeatedly during a real-world underground-garage test.
Why It Matters
The incident highlights the difficulty of validating autonomous-driving systems across rare parking environments and edge cases. For AI and robotics teams, rapid user feedback, reproducibility, and closed-loop issue triage remain essential to improving deployment safety.
What To Do Next
Add underground-garage parking scenarios to your autonomous-driving regression suite, using replayable logs and targeted corner-case simulations.
Key Points
- •The SU7 Ultra’s automated parking failed repeatedly during a real-world underground-garage test.
- •Xiaomi’s automotive product team quickly contacted Wang Teng and began investigating the problem.
- •Wang Teng reproduced the issue and submitted a formal report following Xiaomi’s instructions.
- •Xiaomi characterized the failure as a normal corner-case bug that engineers should resolve quickly.
🧠 Deep Insight
AI-generated analysis for this event.
🔑 Enhanced Key Takeaways
- •The SU7 Ultra utilizes Xiaomi's 'Xiaomi Pilot' autonomous driving system, which relies on a combination of LiDAR, high-definition cameras, and ultrasonic sensors for parking maneuvers.
- •Xiaomi's software development process includes a 'bug feedback mechanism' where executives like Wang Teng act as internal beta testers to identify edge cases before OTA updates.
- •The SU7 Ultra is positioned as a high-performance variant, featuring a tri-motor powertrain that complicates sensor calibration compared to the standard SU7 model.
- •Underground parking failures in the SU7 series have been previously linked to signal attenuation in multi-level concrete structures, a common challenge for vision-based parking algorithms.
- •Xiaomi has committed to a rapid OTA (Over-the-Air) update cycle, typically addressing reported software bugs within 2-4 weeks of internal verification.

🛠️ Technical Deep Dive
- The SU7 Ultra employs a dual-Orin X chip architecture providing 508 TOPS of computing power for autonomous driving tasks.
- Automated parking utilizes a Bird's Eye View (BEV) perception network combined with Transformer-based spatial mapping to navigate tight spaces.
- The system integrates ultrasonic sensor fusion to detect low-profile obstacles that cameras might miss in low-light underground environments.
- Xiaomi's parking algorithm includes a 'memory parking' feature that allows the vehicle to learn specific routes in private garages, which is the likely subsystem affected by the reported bug.
