Adaptive Headlight Glare Avoidance Based on Target Path Prediction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional matrix headlights face challenges in effectively controlling light to avoid glare for vehicles and pedestrians, leading to potential safety issues due to improper light control strategies, especially when dealing with varying vehicle sizes and speeds, and changing road conditions.
Innovation Solution
A vehicle control method that detects target objects in front of the vehicle, determines their position on the traveling path, and performs light control for avoidance based on specific strategies, including selective light control for vehicles with overall dimensions less than or equal to a set dimension, and light extinguishing control based on preset reference values, optimized by scenario modes and slope modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If light control for avoidance is performed for large vehicles, then safety of large vehicles is improved, but the present vehicle may not be able to observe the large vehicle properly
Solution Approach 1:
The patent applies local quality by implementing differentiated light control for large vehicles based on their position relative to the present vehicle. When large vehicles are in specific positions (e.g., adjacent lanes or specific angular ranges), the system selectively extinguishes only certain LED regions rather than all lights, preserving observation capability while still providing avoidance for the large vehicle.
Solution Approach 2:
The system dynamically adjusts light control strategies for large vehicles based on real-time conditions including relative position, speed, and distance. The avoidance strategy is not fixed but changes dynamically according to the operational context, allowing the system to balance observation needs with avoidance requirements.
2Ease of operation
If conventional light control strategies are used, then implementation is simple, but safety and walking experience of pedestrians are affected
Solution Approach 1:
The patent applies local quality by implementing specialized light control strategies for vulnerable road users such as pedestrians, cyclists, and animals. The system identifies these targets and applies differentiated avoidance strategies that prioritize their safety and comfort, such as extinguishing lights in directions toward the vulnerable user while maintaining illumination for other areas.
Solution Approach 2:
The system introduces an intermediary classification layer that categorizes detected objects into different types (vehicle, pedestrian, animal, etc.) and assigns appropriate avoidance strategies. This intermediary classification mechanism enables complex differentiated control while maintaining relatively simple implementation through modular strategy selection.

AI summary
The invention relates to the field of vehicle technologies, and aims to solve a technical problem that when light control for avoidance of a vehicle is improper, traveling safety of the present vehicle, traveling safety of vehicles ahead for which light is controlled for avoidance, and/or safety, walking experience, etc. of the pedestrians for whom light is controlled for avoidance are/is affected to some degree. To solve the technical problem, embodiments of the invention provide a vehicle control method and apparatus, a control apparatus, a vehicle-mounted device, a vehicle, and a computer-readable storage medium. The control method includes: detecting target objects in front of a vehicle; determining whether the target objects are on a traveling path of the vehicle; and performing light control for avoidance for the target objects based on a determination result in a predetermined manner. With this setting, a strategy of light control for avoidance for a target object can be made by learning a traveling path of the target object, such that impact on traveling safety of the present vehicle, traveling safety of vehicles ahead for which light is controlled for avoidance, and/or safety, walking experience, etc. of the pedestrians for whom light is controlled for avoidance are/is kept as little as possible.
