The vehicle takes some time to enter sleep mode after being locked, and the LiDAR continues to work before sleep mode, which is a normal phenomenon.

✓ Long-term Episode 49 · Question 2 2024-07-22

The LiDAR on the Xiaomi SU7 Max seems to still be working after the car is locked. Why is that?

Official answer

After the entire vehicle is locked, it will enter sleep mode after a period of time. The LiDAR will only stop running after the vehicle officially enters sleep mode. Before this, the vehicle controllers are still working, so the LiDAR is also working. This phenomenon is a normal situation, so please do not worry.

Supplementary note

Additional context for the official answer

Vehicle Sleep Mode Definition

Term explained

Sleep mode refers to the low-power state where controllers gradually shut down after locking, not an immediate power-off. LiDAR shutdown timing depends on the system power-down strategy; this is normal logic and does not indicate sensor malfunction or abnormal power consumption.
