Vehicle Lighting Control for Pedestrian Recognition Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Autonomous vehicles lack effective means of communicating with pedestrians and objects in their environment, particularly in real-time, to ensure safe navigation and awareness.
Innovation Solution
A lighting device for moving bodies that senses objects and controls lighting to convey information through light emission, including object count, density, features, and safety priorities, using sensors and a controller to direct light output.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If autonomous vehicle processes data in real-time to recognize driving environments, then the vehicle can inform drivers and perform emergency functions, but pedestrians cannot confirm whether the vehicle recognizes them
Solution Approach 1:
The patent introduces light emission as an intermediary communication channel between the autonomous vehicle and pedestrians. The controller directs lamps to emit light along detected object movement paths, creating a visible signal that conveys recognition information to pedestrians without compromising the vehicle's internal data processing capabilities
Solution Approach 2:
The system implements feedback by projecting light signals back toward detected objects based on their movement paths. This creates a closed-loop communication where the vehicle not only detects objects but also provides visual confirmation to objects that they have been detected, enhancing mutual awareness
2Loss of information
If the lighting device displays detailed object information such as object count, density, features, and safety priorities, then communication with surrounding objects is enhanced, but the device complexity increases
Solution Approach 1:
The patent makes the lighting device multi-functional by enabling it to convey multiple types of information through a single component system. The same lamps used for basic illumination are controlled to display object count, density, features, and safety priorities through variations in light emission patterns, eliminating the need for separate communication devices
Solution Approach 2:
The system encodes multiple information parameters by varying the light emission characteristics. The controller modulates light intensity, duration, and spatial distribution to represent different object attributes such as count, density, and safety priority, allowing rich information communication through a simple light output mechanism
