In-Vehicle Lighting Synchronization via Network Controller
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing in-vehicle lighting systems require aftermarket installations and external power sources to synchronize audio or video sources with ambient lighting, which can be bulky and unattractive, and do not seamlessly integrate with factory-installed systems.
Innovation Solution
An in-vehicle network-controlled lighting system that utilizes the body control module, ambient lighting module, and infotainment center to synchronize audio or video sources with factory-installed ambient lighting through established communication protocols like LIN, CAN, or Ethernet, allowing for synchronized light shows without additional aftermarket lighting or modifications to the existing system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If aftermarket lighting systems are installed to synchronize audio/video with ambient lighting, then lighting synchronization capability is improved, but device complexity and aesthetic appearance deteriorate due to bulky external power sources and additional components
Solution Approach 1:
The patent combines the lighting control functionality with existing vehicle modules (body control module, ambient lighting module, or infotainment center). The in-vehicle network controller integrates multiple functions including media source reception, instruction code generation, and communication with light elements, eliminating the need for separate aftermarket control systems and power sources.
Solution Approach 2:
The invention makes existing vehicle modules multi-functional by enabling them to handle both their original functions and new lighting synchronization tasks. The body control module, ambient lighting module, or infotainment center can now also serve as the in-vehicle network controller for media-synchronized lighting, reducing the need for additional dedicated components.
2Adaptability or versatility
If aftermarket lighting systems are installed to synchronize audio/video with ambient lighting, then lighting synchronization capability is improved, but ease of operation deteriorates due to installation requirements and external power sources
Solution Approach 1:
The system utilizes the vehicle's existing infrastructure (power sources, communication networks, control modules) to provide lighting synchronization functionality. The factory-installed lighting system serves itself by integrating with the vehicle's native control architecture, eliminating the need for owners to install and manage separate power sources and control systems.
3Adaptability or versatility
If factory-installed lighting systems are modified to add synchronization capability, then lighting synchronization capability is improved, but reliability deteriorates due to potential system instability
Solution Approach 1:
The patent incorporates error handling and override capabilities in the instruction code communication protocol before potential problems occur. The system is designed with predetermined protocols for handling communication errors, signal conflicts, and system overrides, ensuring stable operation without requiring reactive modifications or repairs.
Data Source
AI summary
In one embodiment, the in-vehicle network controller sends instructions, via a communication signal, to the lighting network wherein the lighting network is synchronized with a media source by using a communication protocol which controls features of the lighting network such as timing, fading, color, intensity, and enable/disable.
