Solution Overview
Problem
Existing methods for controlling vehicle headlights do not adequately address the impact of street lighting and trees on illumination, leading to potential safety hazards and energy inefficiency in urban environments.
Innovation Solution
A method that adjusts headlight brightness based on the presence of street lighting systems and trees using vehicle sensors, setting different brightness levels to enhance visibility and reduce energy consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the brightness of the headlights is increased to compensate for trees blocking street lighting, then the illumination of the road is improved, but the energy consumption increases and other road users may be dazzled
Solution Approach 1:
The patent applies local quality by adjusting headlight brightness specifically in areas where trees block street lighting, rather than uniformly increasing brightness across all directions. The control unit identifies specific zones with insufficient illumination and directs additional light only to those areas, maintaining energy efficiency while ensuring adequate road illumination where needed.
Solution Approach 2:
The patent implements dynamics by making the headlight brightness adaptive and variable based on real-time detection of street lighting conditions and tree obstructions. The control unit continuously monitors the environment and dynamically adjusts the headlight output, transitioning between different brightness levels as the vehicle moves through areas with varying illumination needs.
2Reliability
If the brightness of the headlights is increased to improve visibility, then road safety is improved, but the risk of dazzling other road users increases
Solution Approach 1:
The patent applies local quality by directing enhanced illumination only toward the road surface and specific areas where trees block street lighting, while controlling the light distribution to minimize glare in directions where other road users may be present. The system optimizes the angular distribution of light to illuminate the road without overwhelming other participants in traffic.
Solution Approach 2:
The patent implements feedback by using sensors to detect the presence of trees and the effectiveness of street lighting, then using this information to adjust headlight brightness accordingly. The control unit receives feedback about environmental conditions and continuously optimizes the headlight output to maintain safety while avoiding excessive glare.
3Use of energy by moving object
If the brightness of the headlights is reduced to save energy, then energy consumption is reduced, but the visibility and illumination of the road deteriorate
Solution Approach 1:
The patent implements dynamics by making the headlight brightness adaptive and variable based on real-time detection of street lighting conditions and tree obstructions. The control unit continuously monitors the environment and dynamically adjusts the headlight output, transitioning between different brightness levels as the vehicle moves through areas with varying illumination needs.
Solution Approach 2:
The patent applies parameter changes by adjusting the brightness parameter of the headlights based on detected environmental conditions. The control unit modifies the light output parameter in response to variations in street lighting availability and tree obstruction, optimizing the balance between energy consumption and road illumination.
Data Source
AI summary
A method for controlling headlights of a motor vehicle, including capturing of environment data of a surroundings of the motor vehicle using sensors of the motor vehicle, wherein the surroundings comprise a road on which the motor vehicle is traveling, detection using the environment data to determine whether street lighting system independent of the motor vehicle is present, detection using the environment data to determine whether there are trees next to the road, and setting of a brightness of the headlights using the results of the detections.
