Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle light control systems require significant effort and resources to implement and modify multiple light distribution arrangements, particularly due to the need for extensive data storage and processing power, which complicates smooth beam adjustments and reconfigurations.
Innovation Solution
A procedure that allows for the generation of multiple light distribution arrangements with reduced computing power and memory usage by interpolating between existing datasets, enabling seamless swiveling of light beams with minimal perceivable optical changes, using a light control system that actuates LEDs in a vehicle's headlamps to adjust light outputs and beam alignments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple light distribution arrangements are implemented with separate datasets, then comprehensive light control functionality is achieved, but computing power requirements and memory capacity increase significantly
Solution Approach 1:
The patent combines multiple light distribution datasets into a single reference dataset representing a basic light distribution arrangement. Instead of storing separate datasets for each light distribution arrangement (low beam, high beam, highway, urban), the system stores one reference dataset and generates all other arrangements by applying specific transformations (scaling, shifting, masking) to this single reference, thereby merging multiple data storage requirements into one
Solution Approach 2:
The single reference dataset serves multiple functions by being transformed into various light distribution arrangements. The reference dataset acts as a universal base that can generate low beam, high beam, highway, and urban light distributions through different processing operations, making one dataset perform the work of multiple separate datasets
2Manufacturing precision
If extensive datasets are stored for each light distribution arrangement, then precise light control is achieved, but memory capacity requirements increase
Solution Approach 1:
Instead of storing original separate datasets for each light distribution arrangement, the system creates transformed copies of a single reference dataset. Each light distribution arrangement (low beam, high beam, etc.) is generated as a processed copy of the reference dataset through scaling, shifting, or masking operations, eliminating the need to store multiple full-sized original datasets
3Adaptability or versatility
If multiple separate datasets are used for different light distributions, then comprehensive coverage is achieved, but processing time and computational effort increase
Solution Approach 1:
The system performs preliminary action by establishing a single reference dataset that already contains the fundamental light distribution pattern. All other light distribution arrangements are generated on-demand through rapid transformations of this pre-prepared reference, eliminating the need to process or retrieve multiple separate pre-stored datasets during operation
4Adaptability or versatility
If the light control system is configured with multiple light distribution datasets, then functionality is comprehensive, but reconfiguration and modification become more difficult
Solution Approach 1:
The patent segments the light distribution control into two independent parts: a reference dataset that defines the basic light distribution pattern, and transformation parameters that define specific arrangements (scaling factors, shift amounts, mask patterns). This segmentation allows modifications to be made by changing only the transformation parameters without affecting the core reference dataset, simplifying reconfiguration

Data Source
AI summary
A procedure is provided for actuating at least one light module of the light unit of a vehicle with a plurality of light sources and a light control system automatically actuating the light module. At least two first light distribution arrangements are generated and first data sets corresponding to the first light distribution arrangements are stored in a memory of the light control system. In order to implement a plurality of light distribution arrangements with less effort, at least one second light distribution arrangement is allocated to at least one pairing of two of the at least two first light distribution arrangements, and actuation of the light module for generating this at least one second light distribution arrangement is performed depending on the first datasets of the assigned pairing from the first light distribution arrangements.
