Vehicle Lighting Control for Visibility Without Higher Power Use
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Despite adequate combined light from streetlights and vehicle lights, visibility in traffic environments can be degraded due to inappropriate lighting states, including insufficient light amount, range, color, or flashing states.
Innovation Solution
A lighting management system that includes a judgement unit to assess the lighting state against predefined references and control units to adjust the light amount, range, color, and flashing state of both vehicle and environmental lighting apparatuses to ensure optimal visibility, using a server to determine and enforce these adjustments based on environmental factors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the light amount of streetlights and vehicle lights is increased to improve visibility, then visibility is improved, but power consumption increases
Solution Approach 1:
The system dynamically adjusts lighting parameters (light amount, range, color, flashing state) based on real-time environmental conditions and detection results, optimizing visibility while minimizing power consumption by avoiding unnecessary high-intensity lighting in all conditions
Solution Approach 2:
The system uses detection units to monitor the actual lighting state and provides feedback to the control unit, which then adjusts the lighting apparatus accordingly to maintain optimal visibility without excessive power consumption
2Illumination intensity
If only the light amount is increased to improve visibility, then brightness is improved, but other lighting qualities (range, color, flashing state) remain inadequate
Solution Approach 1:
The control system divides the lighting control into separate dimensions (light amount, range, color, flashing state), with dedicated control parameters for each aspect, allowing independent optimization of each lighting quality parameter
Solution Approach 2:
The system dynamically adjusts multiple lighting parameters simultaneously based on real-time conditions, transitioning from static single-parameter control to dynamic multi-parameter control that adapts to changing environmental requirements
3Reliability
If the lighting state is optimized for visibility, then safety is improved, but the system complexity increases due to multiple control parameters
Solution Approach 1:
The control unit serves multiple functions by managing different lighting parameters (amount, range, color, flashing state) through a single integrated system, reducing overall system complexity despite the multi-dimensional control requirements
Solution Approach 2:
The system automatically adjusts lighting parameters based on environmental detection without requiring manual intervention, with the control unit self-regulating the lighting apparatus to maintain optimal safety conditions

AI summary
The lighting management system includes: a judgement unit configured to judge whether or not a lighting state around a vehicle based on a first lighting apparatus and a second lighting apparatus meets a first reference for a light amount and a second reference for at least one of a lighting range, a lighting color, and a flashing state; a first control unit configured to control the light amount of at least one of the first lighting apparatus and the second lighting apparatus so that the lighting state is brought to meet the first reference; and a second control unit configured to control at least one of the lighting range, the lighting color, and the flashing state of at least one of the first lighting apparatus and the second lighting apparatus so that the lighting state is brought to meet the second reference.
