Led Matrix Control Unit, Basic Function - GF82.10-P-9891A

Vehicles with adaptive LED illumination 

Overview 

This document contains information on:

• General 
• Function 

General 

The LED matrix control units are located on the outer side of the respective front lamp unit.

The LED matrix control units are screwed to the housing of the respective front lamp unit. The LED matrix control units are connected to the vehicle-side wiring harness via the front lamp units.

Function 

The LED headlamps are equipped with "multibeam technology". The light sources for implementing the high beam function are each equipped with several LEDs that can be actuated independently of one other. Depending on which LEDs are actuated, the shape and, depending on the version of the LED headlamps, the intensity of the light cone can be influenced.

The LED matrix control units are connected to the vehicle's network architecture.

The LED matrix control units actuate the following functions:

• Low beam
• High beam
• Thermal management (temperature monitoring and fan control)

To implement the exterior lighting functions, the LED matrix control units process, among others, the following information:

• Circuit status
• Temperatures in the front lamp units
• Switch on low beams request
• "Switch on high beams" request
• Object information for automatic high beam
• Request "Switch on fan motor"
• Status of intelligent headlamp control (variable light distribution)
• Light distribution request, intelligent headlamp control (variable light distribution)

The LED matrix control units process these input factors and send, among others, the following information:

• Low beams status
• High beam status
• Light distribution status
• "Show display messages" request
