Dynamic Bending ADB Head Lamp Steering Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ADB head lamps with matrix type functions maintain a fixed high beam pattern despite changes in steering angle, leading to reduced visibility on curved roads, especially as the central region remains brighter than the periphery.
Innovation Solution
A dynamic bending ADB head lamp system that adjusts the central region of the high beam by changing current values to match steering angle changes, utilizing a steering angle sensor and LED array to control individual LEDs, without requiring a separate driving motor, thereby improving visibility and reducing manufacturing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a fixed high beam pattern is maintained in conventional ADB head lamps, then the manufacturing cost is reduced and the structure is simplified, but the driver visibility on curved roads deteriorates as the central region does not follow steering angle changes
Solution Approach 1:
The patent implements dynamic beam pattern adjustment by detecting steering angle changes and dynamically shifting the central LED activation region accordingly. This allows the high beam pattern to adapt to curved road conditions while maintaining a relatively simple structure without complex mechanical components.
Solution Approach 2:
The patent changes the activation parameters of LED arrays based on steering angle detection. By dynamically adjusting which LEDs are activated in the central region versus peripheral regions, the system optimizes visibility on curved roads without requiring physical movement of the entire headlamp assembly.

AI summary
The present disclosure relates to a dynamic bending ADB head lamp system and a method for controlling the same that, in an ADB or a high beam operation of a vehicle equipped with a head lamp of a matrix type having an ADB function, may move a central region of a high beam in a direction of a movement of the vehicle in response to a change in a steering angle of the vehicle to improve visibility of a driver, and move the central region of the high beam by changing only a current value without a separate driving motor to reduce a manufacturing cost.
