Vehicle Terminal Lighting Synchronization via Illuminance Mapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Inconsistent lighting between vehicle interior devices and external terminals can lower driver visibility and convenience, as existing systems fail to integrate lighting control effectively.
Innovation Solution
A vehicle-interlocked terminal lighting control system that uses an integrated lighting control interlocking setting unit, a lighting setting initialization unit, and a lighting controller to generate an illuminance mapping table and synchronize lighting between vehicle interior and terminal lighting based on illuminance levels, connection states, and battery charge information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If terminal lighting is controlled independently from vehicle interior lighting, then terminal lighting can be adjusted freely, but lighting inconsistency occurs between terminal and vehicle devices
Solution Approach 1:
The patent merges terminal lighting control with vehicle interior lighting control by establishing an illuminance mapping relationship between the terminal and vehicle illuminance sensor. The lighting controller integrates both lighting systems, using the illuminance mapping table to synchronize terminal lighting brightness with vehicle interior lighting brightness, thereby achieving consistent lighting across all devices while maintaining adjustable terminal lighting through the mapping relationship.
2Illumination intensity
If integrated lighting control is implemented between vehicle and terminal, then lighting consistency is improved, but system complexity increases
Solution Approach 1:
The patent introduces an illuminance mapping table as an intermediary component that simplifies the integrated lighting control system. The mapping table stores predefined relationships between vehicle illuminance levels and terminal illuminance levels, allowing the lighting controller to automatically determine terminal lighting brightness based on vehicle interior lighting conditions without requiring complex real-time calculations or additional sensors.
3Illumination intensity
If illuminance mapping table is generated based on maximum illuminance values, then lighting synchronization is achieved, but eye strain may occur due to excessive brightness
Solution Approach 1:
The patent changes the illuminance mapping parameters by considering battery charge amount as an additional factor. When battery charge is below a threshold, the system generates an illuminance mapping table with reduced terminal illuminance values compared to the maximum possible brightness. This parameter adjustment ensures lighting synchronization is maintained while preventing excessive brightness that would cause driver eye strain during low-battery conditions.
