AI Technical Summary

Technical Problem

Existing steering wheel ambient lighting has limited functionality, poor optical effects, and cannot be integrated with core vehicle functions such as steering and autonomous driving, thus affecting driving safety and experience.

Method used

The lampshade assembly adopts a three-layer structure, including a protective shell, a light guide lampshade, and a diffuser lampshade. Together with a sealed end cap, a lamp base, and a matching frame, it can achieve multi-scene linkage. Through the MCU controller, it interacts with the vehicle computer signal to achieve various lighting display effects.

Benefits of technology

It enables multi-scenario linkage between lights and vehicle steering, ADAS mode, and voice assistant, improving driving safety and experience. The light is uniform and soft, does not affect the driver's vision, and is easy to install with good sealing.
