Vehicle Signaling Apparatus for Detection Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication systems for vehicles do not effectively interact with their surroundings to prevent dangerous situations, particularly for autonomous vehicles that lack a human driver to detect and acknowledge pedestrians or other traffic participants, leading to potential accidents.
Innovation Solution
A communication device and method that includes a recording apparatus and a signaling apparatus, which sends a recording signal to the surroundings based on detected objects, using optical, acoustic, or radio signals to indicate detection and classification of traffic participants, enabling nonverbal communication and improving vehicle guidance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If autonomous vehicles use recording apparatus to detect surroundings, then vehicle guidance reliability is improved, but traffic participants cannot verify they have been detected leading to safety issues
Solution Approach 1:
The patent implements a feedback mechanism where the vehicle's recording apparatus detects traffic participants and sends detection information back to them via signaling apparatus. This allows traffic participants to verify they have been detected, creating a closed-loop communication system that resolves the information asymmetry between vehicle and surroundings.
Solution Approach 2:
The patent introduces signaling apparatus as an intermediary component that translates the vehicle's detection data into communicable signals for traffic participants. This intermediary enables the transfer of detection verification information from the vehicle's internal recording system to the external environment, solving the problem of information loss.
2Reliability
If vehicles send detection information to surroundings, then traffic safety is improved, but device complexity increases due to additional signaling apparatus
Solution Approach 1:
The patent integrates the signaling apparatus with the existing recording apparatus and vehicle control systems, allowing the same hardware components to serve multiple functions. The recording apparatus both detects surroundings and provides data for signaling, while the signaling apparatus communicates with both vehicle control systems and external traffic participants, reducing overall system complexity despite added communication capabilities.
