Solution Overview

Problem

Existing adjustable lighting systems for carrier vehicles are inadequate in providing suitable lighting performance, particularly in distant lighting scenarios and often dazzle the drivers of target vehicles, as they primarily rely on azimuth adjustments of dipped beam headlights and lack effective control over high beam modules.

Innovation Solution

The method involves controlling low beam lighting and high beam light source modules to operate simultaneously, with selective adjustments to avoid dazzling detected target vehicles, using separate modules with a blanking device, presence detection, and ambient luminosity measurement to dynamically adjust lighting based on the relative positioning of vehicles and ambient conditions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Length of moving object

If high beam modules are used to improve distant lighting performance, then illumination range is extended, but target vehicle drivers are dazzled

Engineering Contradiction:
Improveillumination rangeVSAvoiddazzling of target vehicle drivers
Core Design Contradiction:
Length of moving objectVSObject-affected harmful factors

Solution Approach 1:

The lighting system is divided into separate low beam and high beam modules, with each high beam module independently controllable. This segmentation allows selective activation and adjustment of high beam segments to illuminate specific zones while avoiding areas where target vehicles are present, thus extending illumination range without causing dazzling.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The high beam illumination is selectively adjusted to provide different lighting qualities in different spatial zones. The system determines presence zones of target vehicles and adjusts high beam modules to illuminate areas outside these zones, creating local variations in illumination quality that maximize visibility while minimizing dazzle to target vehicle drivers.

Inventive Principle:
Principle #3Local quality

2Adaptability or versatility

If azimuth adjustment of dipped beam headlights is used, then lighting direction is adaptable, but lighting performance for distant illumination is insufficient

Engineering Contradiction:
Improvelighting direction adaptabilityVSAvoiddistant lighting range
Core Design Contradiction:
Adaptability or versatilityVSLength of moving object

Solution Approach 1:

The system merges the functions of dipped beam headlights and main beam headlights into a coordinated lighting system. Both low beam and high beam modules operate simultaneously with complementary functions, where low beam provides adaptable directional lighting and high beam modules extend distant illumination, achieving both adaptability and long-range performance.

Inventive Principle:
Principle #5Merging (Combining)

3Illumination intensity

If high beam intensity is increased to improve visibility, then illumination intensity is enhanced, but target vehicle drivers are dazzled

Engineering Contradiction:
Improvebeam intensityVSAvoiddazzling of target vehicle drivers
Core Design Contradiction:
Illumination intensityVSObject-affected harmful factors

Solution Approach 1:

The system applies different illumination intensities to different spatial zones. High beam modules are selectively adjusted to provide high intensity illumination in areas where no target vehicles are present, while reducing or eliminating illumination in presence zones of target vehicles, thus enhancing visibility without causing dazzle.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The system uses detection of target vehicles to provide feedback for dynamic adjustment of high beam intensity and direction. When target vehicles are detected, the system adjusts high beam modules to avoid illuminating their presence zones, creating a feedback loop that maintains high illumination intensity where needed while preventing dazzle to other road users.

Inventive Principle:
Principle #23Feedback

AI summary

Method for controlling an adjustable illuminating system, for a carrier vehicle (10), which method comprises setting the illumination outside of the at least one zone (30S) of presence of a target vehicle (30) detected as moving in front of the carrier vehicle. When the illuminating system must illuminate in front of the carrier vehicle (10) under low light conditions, a low beam (LB) illumination is requested to function and left and right high beam light source modules are, on the one hand, requested to function simultaneously to the low beam illumination, and on the other hand, are selectively regulated to the left and right in order to provide selective high beam (SB) illumination outside of said at least one zone (30S) of presence of a target vehicle when at least one such target vehicle (30) is detected. Illuminating system implementing said method and vehicle equipped with such an illuminating system.
