Vehicle Interior Lighting Control With Visual Color-Zone Profiles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for controlling vehicle interior lighting lack intuitive and clear methods for selecting and assigning colors to different zones, leading to complexity in creating desired ambiances and interactions between colors.
Innovation Solution
A method and device that allow users to select arrangement profiles and colors for multiple color zones using a touch-sensitive display and operating device, with graphical representations and virtual control elements, enabling improved feedback and simplification of color assignments and interactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple color zones are implemented in vehicle interior lighting, then ambiance creation capability is improved, but control complexity increases
Solution Approach 1:
The interior lighting system is segmented into multiple independently controllable color zones (e.g., driver zone, passenger zones, footwell zones). Each zone can be controlled separately through individual control elements, allowing complex ambiance creation while maintaining manageable control structure through modular organization of control interfaces.
Solution Approach 2:
The control interface displays a two-dimensional graphical representation of the vehicle interior where users can visually select and control lighting parameters for different spatial zones. This graphical dimension provides intuitive feedback about which zones are active and their current settings, reducing the cognitive load of controlling multiple color zones.
2Adaptability or versatility
If detailed control options are provided for each color zone, then lighting customization is improved, but ease of operation deteriorates
Solution Approach 1:
The system provides automatic zone detection and activation based on vehicle state (e.g., which doors are open, which seats are occupied). When a door is opened, the corresponding footwell zone is automatically activated, reducing the number of manual control actions required while still allowing detailed customization when desired.
Solution Approach 2:
The graphical display provides real-time visual feedback showing which zones are currently active and their lighting parameters. This immediate feedback helps users understand the effect of their control actions and makes it easier to achieve desired lighting configurations without trial and error.
3Loss of information
If real-time visual feedback of lighting effects is displayed, then user understanding of color assignments is improved, but information processing load increases
Solution Approach 1:
The system creates a simplified graphical copy or representation of the physical vehicle interior lighting system. This virtual model displays the current state of each lighting zone and allows users to preview color assignments before they are applied, providing clear visual feedback without requiring complex real-time rendering of actual light effects.

AI summary
The invention relates to a method for controlling the interior lighting (5) of a vehicle (50). Multiple lighting units (4-x) are distributed in the interior of the vehicle (50), and each of the lighting units (4-x) is assigned at least two color zones (A, B). Arrangement profiles (21-x) for arranging the at least two color zones (A, B) in the interior of the vehicle (50) are displayed on a display and operating device (2), and a user selection of one of the arrangement profiles (21-x) is detected. A color selection by the user is detected for each of the at least two color zones (A, B) by means of a respective operating element (23-x) displayed on the display and operating device (2), and a color is set for each lighting unit (4-x) by a controller (3) according to the selected arrangement profile (21-x) and the colors selected for the at least two color zones (A, B). The invention also relates to a device (1) for controlling the interior lighting of a vehicle.
