Vehicle Light Module Actuation with Distribution Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle light units struggle to adaptively adjust light distribution to varying driving situations while ensuring compliance with legal regulations, which can lead to suboptimal illumination and potential non-compliance with statutory requirements.
Innovation Solution
A procedure that utilizes status and surroundings recognition devices, such as steering-angle sensors and front cameras, to adjust the light distribution of vehicle light modules, ensuring compliance with legal illuminance standards by comparing the current light distribution with stored legal standards and dynamically adjusting the light beam's illuminance and spatial alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the light distribution is adjusted to optimize illumination for the driving situation, then the driver safety and visibility are improved, but the compliance with legal illuminance regulations may be compromised
Solution Approach 1:
The system employs a light distribution recognition device that captures the actual light distribution emitted by the light module and feeds this information back to the light control system. The control system compares the captured distribution with legally prescribed distributions and adjusts the light module actuation accordingly, creating a closed-loop control that ensures both optimization and compliance.
Solution Approach 2:
The patent implements dynamic adjustment of light distribution by continuously monitoring the captured light distribution and modifying the light module actuation in real-time based on the comparison with legal standards. This allows the system to adaptively optimize illumination while maintaining compliance under varying driving conditions.
2Adaptability or versatility
If the light module is actuated to provide enhanced illumination in specific areas, then the visibility and driver safety are improved, but the light distribution may deviate from statutory regulations
Solution Approach 1:
The light distribution recognition device continuously monitors the actual light distribution and provides feedback to the control system. This feedback mechanism enables the system to maintain precise control over light distribution characteristics while adapting to different driving situations, ensuring both adaptability and accuracy.
Solution Approach 2:
The system replaces traditional mechanical adjustment mechanisms with an electronic control system that uses optical sensors and computational algorithms to precisely control light distribution. This substitution enables more accurate and flexible control while maintaining compliance with regulatory standards.
3Reliability
If the light control system continuously monitors and adjusts light distribution, then the compliance with regulations is ensured, but the system complexity increases
Solution Approach 1:
The light distribution recognition device serves multiple functions: it identifies the light distribution characteristics, compares them with legal standards, and provides feedback for adjustment. This multi-functionality reduces the need for separate dedicated components for each function, thereby managing system complexity while ensuring compliance.
Solution Approach 2:
The control system automatically performs the comparison between captured light distribution and legal standards, and autonomously adjusts the light module actuation without requiring external intervention. This self-service capability simplifies the overall system architecture by integrating multiple functions into a single automated control loop.
