Product Description:

 
Auto headlamp control unit 
OE number: 31335777
Applicable vehicle type: For Volvo
 
 
 
The headlight module is equivalent to the 'intelligent brain' of the vehicle's lighting system. It is an integrated ECU that receives multiple signals such as body height, vehicle speed, steering wheel angle, and light intensity. After processing by the MCU, it drives motors, LED driver chips, or lasers to achieve precise control over the lighting functions including on/off status, brightness, illumination angle, and light distribution pattern.
 
 
Core Functions

• Automatic Activation/Deactivation: Utilises light sensors to detect tunnels, dusk, and adverse weather conditions, achieving 0.2-second response times upon entry/exit, eliminating manual operation.
• Adaptive Front Lighting System (AFS): Adjusts illumination in real-time based on vehicle speed and steering angle, with horizontal ±15° and vertical ±5° adjustment, reducing blind spots in bends by approximately 30%.
• Adaptive High Beam (ADB): Matrix/laser headlights with 50-100 independent LEDs selectively deactivate sections for oncoming/leading vehicles to prevent glare, while maintaining full high-beam coverage in open areas with up to 400m illumination range.
• Load-Level Adjustment: Utilises front/rear body height sensors to automatically lower the light beam angle when the boot is fully loaded or additional passengers are present, preventing glare for oncoming drivers.
• Energy Saving & Extended Lifespan: Automatically reduces LED current by 30% when the vehicle is stationary, balancing energy consumption and heat dissipation; supports cold start soft-start functionality, extending bulb lifespan by 20%.
