Vehicle Headlight Alignment via Preliminary Pivoting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing high beam assistance systems in vehicles do not efficiently adjust the headlight illumination to avoid blinding oncoming or preceding vehicles, leading to reduced driving comfort and delayed optimal illumination due to hectic changes in light distribution.
Innovation Solution
A method and device that classify nearby vehicles and determine a target position for the headlight independently of passing vehicles, allowing for early pivoting and optimal light distribution adjustment, reducing blinding and enhancing illumination efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the headlight switches over to optimal light distribution only after another vehicle has passed, then the other vehicle is not blinded, but the driver experiences delayed illumination and reduced driving comfort
Solution Approach 1:
The headlight system performs preliminary action by pivoting the headlight to the target position in advance, before the other vehicle has completely passed. This early positioning ensures that when the light distribution switches occur, the headlights are already oriented correctly, providing optimal illumination without delaying the transition. The system calculates the target position based on the relative motion of the other vehicle and initiates the pivoting action proactively, resolving the contradiction between avoiding blinding and maintaining timely illumination.
2Object-affected harmful factors
If the headlight waits until the other vehicle has passed to switch light distribution, then blinding is avoided, but hectic changes in light distribution occur which bother the driver
Solution Approach 1:
The system applies preliminary action by completing the headlight pivoting to the target position before the light distribution switch occurs. This ensures that when the illumination pattern changes, the headlight is already properly oriented, avoiding hectic changes that would bother the driver. The preliminary positioning smooths the transition and maintains driver comfort while still preventing blinding of other vehicles.
Solution Approach 2:
The system uses feedback from detecting the position and motion of other vehicles to dynamically adjust the headlight target position and timing. By continuously monitoring the surroundings and adjusting the pivoting action accordingly, the system optimizes the light distribution transitions to avoid both blinding other vehicles and creating disruptive changes for the driver, thereby maintaining ease of operation.
3Illumination intensity
If multiple changes in light distribution are made to achieve optimal illumination, then the illuminated area is optimized, but the frequent changes become bothersome to the driver
Solution Approach 1:
The system performs preliminary pivoting of the headlight to the calculated target position before making light distribution changes. This preliminary action ensures that all necessary orientation adjustments are completed in advance, allowing multiple illumination optimizations to occur without requiring corresponding pivoting changes that would bother the driver. The separation of positioning and illumination adjustment reduces perceptible changes for the driver.

AI summary
A method for aligning an illuminated area of a headlight of a vehicle as a function of the surroundings of the vehicle, includes classifying at least one other vehicle in the surroundings of the vehicle as a function of a piece of information concerning a position of the other vehicle in relation to the vehicle, determining a target position of the headlight, with disregard of the other vehicle, when the other vehicle is classified as passing the vehicle or as being passed by the vehicle, and providing a signal for moving the headlight into the target position while the vehicle is being passed by the other vehicle or is passing the other vehicle.
