Intelligent Motorway Flasher Headlight with Segmented Beam Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing headlight flasher function in motor vehicles can blind and distract drivers in adjacent lanes, as it activates high beam distribution across multiple lanes, potentially causing irritation and safety hazards during 'flash-to-pass' scenarios.
Innovation Solution
A control device that receives lane and object information from recognition systems to generate a modified high beam distribution, spatially restricting the illumination to only the vehicle directly ahead, using segmented light distributions and object recognition to adapt the light pattern based on lane conditions and vehicle distance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If high beam distribution is activated across multiple lanes for headlight flasher function, then the signaling function is effective for flash-to-pass, but drivers in adjacent lanes are blinded and distracted
Solution Approach 1:
The patent applies local quality by making different parts of the headlight system perform different functions: the lighting device is divided into multiple light segments that can be independently controlled, allowing the high beam to be directed only at the target vehicle in the same lane while leaving adjacent lanes unilluminated, thus signaling effectively without blinding other drivers
Solution Approach 2:
The headlight is segmented into multiple independently controllable light segments arranged in a matrix pattern. This segmentation allows selective activation of specific segments to create a focused beam pattern that targets only the vehicle ahead in the same lane, resolving the contradiction between effective signaling and avoiding distraction to adjacent lane drivers
2Object-affected harmful factors
If high beam is directed only at the vehicle directly ahead, then adjacent lane drivers are not blinded, but the signaling effectiveness for flash-to-pass is reduced
Solution Approach 1:
The lighting system dynamically adjusts the illumination pattern based on real-time detection of lane markings and target vehicle position. The control device continuously modifies which light segments are activated to maintain optimal signaling effectiveness while avoiding adjacent lanes, adapting the beam pattern to the specific traffic situation
Solution Approach 2:
The system uses feedback from lane recognition devices and object recognition systems to continuously monitor the positions of lane markings and other vehicles. This feedback enables the control device to adjust the light segment activation pattern in real-time, ensuring the high beam remains focused on the target vehicle while avoiding adjacent lanes

AI summary
The invention relates to a lighting device for a motor vehicle (10) which has one or preferably two such lighting devices, said lighting device being designed to generate a flasher signaling function. The lighting device is paired with a controller, and when the flasher signaling function is activated, the controller actuates the lighting device such that a flasher light distribution, in particular in the shape of a high-beam distribution (LHV), is generated by the lighting device, in particular for a defined period of time, in a region in front of the motor vehicle (10). If the motor vehicle is located on a multilane roadway (FB) which can be traversed in only one direction (R) and is following a motor vehicle (20) on the lane (FS1) of the motor vehicle (10), the at least one lighting device is designed to generate a modified flasher light distribution in a manner corresponding to control commands of the controller (7), wherein solely a sub-region (LHV') of the region (LHV) which can be illuminated by the unmodified flasher light distribution is illuminated with the modified flasher light distribution.
