Vehicle Exterior Light Signaling for Marshaling Status Diagnosis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In vehicle marshaling environments, issues arise in the connection between vehicles and infrastructure, making it difficult to diagnose problems timely, which can lead to traffic congestion.
Innovation Solution
A method and system for wirelessly communicating vehicle status information via exterior lights, using autonomous vehicle marshaling algorithms to perform diagnostic processes and output visual cues through vehicle lights to indicate connectivity, provisioning, and onboarding statuses, and halt navigation if faults are detected.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wireless communication between vehicles and infrastructure is established for monitoring, then vehicle status can be tracked, but connection issues arise that are difficult to diagnose timely
Solution Approach 1:
The patent uses exterior vehicle lights to display different colors or blinking patterns that correspond to specific marshaling statuses, wireless connection states, and diagnostic information. This visual feedback mechanism allows operators to quickly identify connection issues and vehicle status without complex diagnostic tools, directly addressing the difficulty of timely detection while maintaining reliable monitoring.
2Loss of information
If exterior lights are used to indicate vehicle status, then real-time visual feedback is provided, but energy consumption increases
Solution Approach 1:
The system uses periodic or intermittent lighting patterns rather than continuous illumination to convey status information. The exterior lights activate only when status changes occur or at scheduled intervals, providing necessary visual feedback while significantly reducing energy consumption compared to continuous operation.
3Measurement precision
If autonomous vehicle marshaling algorithms perform comprehensive diagnostic processes, then diagnostic accuracy improves, but system complexity increases
Solution Approach 1:
The marshaling system is divided into independent functional modules including wireless communication modules, diagnostic modules, and exterior light control modules. Each module operates autonomously and communicates through standardized interfaces, allowing comprehensive diagnostics to be performed through coordinated module interactions without requiring a monolithic complex system architecture.

AI summary
A method of wirelessly communicating status information of one or more vehicles with one or more infrastructures including the receipt of an onboarding process trigger based on a current status associated with a pre-onboarding process of the one or more vehicles, the determination of a current status associated with an onboarding process of the one or more vehicles based on the onboarding process trigger and an autonomous vehicle marshaling algorithm, and the output of an indication corresponding to the current status associated with the onboarding process of the one or more vehicles via exterior lights of the one or more vehicles to the one or more infrastructures or one or more human operators.
