AI Technical Summary

Technical Problem

The steering wheel is prone to vibration during the return-to-center process due to its own inertia, which affects the handling feel.

Method used

The system employs a first photoelectric sensor, a second photoelectric sensor, and a third photoelectric sensor working in concert. A circuit board controls the drive components to drive the second rotating component and the main shaft to rotate, achieving a smooth return of the steering wheel to center. Combined with the planetary gear reduction mechanism and the cooperation of magnetic components and angle Hall sensors, the system precisely controls the return-to-center process of the steering wheel.

Benefits of technology

It improves the vibration during the steering wheel return process, enhances the handling feel, and strengthens the stability and control precision of the steering wheel assembly.
