AI Technical Summary

Technical Problem

Traditional high beam systems cannot intelligently adjust to complex and changing driving environments, which can easily cause glare interference when meeting oncoming traffic, affecting the safety and comfort of nighttime driving.

Method used

By acquiring the target vehicle's driving environment, vehicle characteristics, and driver status, a multi-layered lighting scheme is generated. Taking into account factors such as ambient light intensity, weather conditions, road type, vehicle distance, and driver physiological indicators, the high beam's illumination angle and intensity are dynamically adjusted to generate a personalized lighting scheme.

Benefits of technology

It has improved the intelligence and adaptability of high beam control, ensuring the safety and comfort of driving at night.
