AI Technical Summary

⚠Technical Problem

Existing motor vehicle lighting systems face challenges with high production costs and space constraints due to the need for multiple control units with data reception capabilities on the vehicle's data bus, especially when managing a large number of light sources.

⚗Method used

A control module with a first control unit equipped with data reception means and multiple slave control units lacking data reception capabilities, connected via electronic circuits, where the first unit manages power supply and activation of all units, reducing the need for individual data reception on each unit.

🎯Benefits of technology

This configuration reduces production costs, minimizes component count, and optimizes space usage while ensuring effective control and fault detection across multiple light sources.
