Adaptive Vehicle Interior Lighting for Passenger Posture Changes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle interior lighting systems are inflexible and often fail to adjust light distribution based on passenger position, posture, or seat configuration, leading to inadequate lighting and passenger inconvenience in autonomous driving scenarios.
Innovation Solution
An interior lighting system with adjustable light sources and a controller that collects passenger information to dynamically adjust brightness, color temperature, and radiation area based on seat position, reclining angle, and swiveling, ensuring optimal lighting for each passenger.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the light distribution angle of interior lights is increased to radiate light to all positions of a seat, then light coverage area is improved, but light is unnecessarily radiated to other passengers causing waste
Solution Approach 1:
The patent applies local quality by providing different lighting conditions to different spatial zones. Multiple interior lights are positioned to illuminate specific seat areas individually, allowing each light to target a localized region rather than using a single wide-angle light source. This enables precise control over where light is directed, ensuring that light is radiated only to the intended passenger area and not to other passengers, thus solving the contradiction between coverage area and energy waste.
2Ease of manufacture
If interior lights are installed at fixed positions above front and back seats, then installation simplicity is improved, but lighting adaptability to changing seat positions is worsened
Solution Approach 1:
The patent implements dynamics by making the lighting system adaptive to changing seat configurations. While lights remain installed at fixed positions for simplicity, the system dynamically adjusts which lights are activated based on real-time seat position detection. When seats are repositioned (e.g., in autonomous driving modes where seats can face each other or arrange in circles), the control system identifies the new passenger locations and activates the appropriate lights to maintain proper illumination, thus achieving adaptability without compromising installation simplicity.
3Adaptability or versatility
If seat positions are made configurable to allow various seating arrangements, then passenger comfort and versatility are improved, but lighting coverage accuracy is worsened due to fixed light positions
Solution Approach 1:
The patent employs feedback by implementing a control system that continuously monitors seat position information and uses this data to adjust lighting activation. Sensors or detection devices track the positions of configurable seats, and this information is fed back to the control unit, which then determines which interior lights should be activated. This closed-loop feedback mechanism ensures that lighting coverage remains accurate and appropriately targeted regardless of how seats are arranged, resolving the contradiction between seating flexibility and lighting precision.

AI summary
A vehicle lighting system in the interior of a vehicle adjusts the radiation area, the brightness, and the color temperature of light depending on the behavior, state, and posture of the passenger, so as to improve passenger convenience and upgrade interior lighting.
